Greene County has more wnmined coal than any other county in Pennsylvania and is estimatec to contain one-fourth of the reserves of the Pittsnurgh coal in the State. So far extensive coal sears has been limited to the Monongahela River district where the Pitts- burgh coal OUTCTODS » The impcrtant coels, with the excez tion of the Waynesburg bed, have no outcroys in the county west of Mononge- hela River, and lic at -reat depth. Since the more easily accessible coal . along the river is rapicly being worked out, shaft mining has Started in other parts of the county. Driliing for oil and gas has shown several other coals below the Pittsburcvh bed but their identity is uncertain and it is impossible at present to estimate their tonnage. Their development will be delayed because of their great depth. In 1918 Greene County stood thirteenth among the counties in Pennsylvania producing» Bee coal, with an output of 1,269,425 tons, valued at $3,309, Of this quantity 1,098,505 tons vere loadeé at the mine for eta 1t; 50,265 tons were sold to local trade and used by emplovees; 32 ery tons were usec at the mines for Steam and heat; 108,355 tons valued at $254,630 were made into coke at the mines. The Pittsburgh ¢coal furnished most of this output and also practically all the coke. Greene County has at least eight workable coals The Pittsburgh co2el is the only one that-can be worked over large areas; the others are workeble only locally, because they are for the most part too thin and dirty to be commercially valuable. Thirty beds are known in the county, They range from a few inches to 6 feet thick, but ~ ~ : ; Cott Pica, Nef Mee heen Fo” SN A ; : EAR 1 Ne ae ae “A ‘ tS . a ne bye Ph ; ae Re ve ‘ i nye 08 l 38 .

Greene Sounty forms the southvesterm corner of the State. It is boundeé on the north by Washington County; on the east by Fayette County and on the south and west by West Virginia. Its maximum length is 32 miles, its maximum width 19 miles, and its area is 590.4 square miles. Its 1920 population was 30,804. The river district, from which most of the production comes, has ample transportation facilities. The Monongahela division of the Pennsylvania railroad follows the valley of Monongahela River south from Pittsburgh, and carries coal both north and south. The Mononga- hela with its locks offers another means of transvortation to Pitts- burgh an@ points to the south. The central and western parts of the county are not well served by railroads. The Wheeling coal railroad enters the county from West Virginia at the state line near the northern county line and follows that line a few miles and then enters YJaShington County. The Waynesburg and Washington railroad runs between Washington and Waynesburg. The Morgantown and heeling railroad, which connects with the lonongahela division of the Penn- Sylvania railroad at a point north of Morgantown, West Virginia, onens up &@ small district in the southern part of the county. In the absence of railroads, much coal is hauled over the highwavs for local and domestic use. These highways are mostly dirt roads and are good in summer but nearly impassable in winter. The county is decidecly hilly. It is a thoroughly dissected region with a relief of about 800 feet. The elevations range from 860 to 1600 feet. Narrow ridges and rounded Imobs with steep slopes at their base are characteristic. The streams have entrenched them- selves in narrow valleys with rather steep slopes. Terraces and benches occur along the larger tributaries, particularly in the eastern portion of the county. ? STRUCTURE, Greene County is crossec in a general northeast-southwest direction by a number of anticlines and synclines forming a series of waves Which, from east to west, are as follows: Lambert syncline, Brownsville anticline, Whiteley syncline, Bellevernon anticline, Waynesburg syncline, Amity anticline, Nineveh syncline, and Washing- ton anticline. They reach their highest point, 750 feet above sea, on the Rrownsvilie anticline near Willow Tree and their lovest point on the Nineveh syneline, in which the Pittsburgh coal is only 100 feet above sea level and more than 1,000 feet below the surface. The Dottom of the Pittsburgh coal was used as a datum plane for drawing the structure contours. The Lambert syncline begins at Jillow Tree and extends northeast across Monongahela River. The Pittsburgh coal is 450 feet above tice - 2 = Na ba mi hi Ay i Mis ie ; Vie May Toma en) PON Naat Nye Guan Rae Wi SCR ; Neh ih " ih) of ‘> : i A ui Ay he Ay : Tee Mek a), rere y i AEDS ” Nod AVIRA 9) 8 ge Ma phat ey eee eve spn "4 rt ty ie Aasaps yal Ne yy 4 we A ‘ ail \ iy meh oe wad ‘ Bue \ ips Hal y, UR Dt TAAY ee .

The slopes are gentile on both flanrs of the basin. The rocks rising to the west form an irregular arch, the Browns- ville anticline. This structure is irregular and not well defined in Greene County. The Whiteley Enaiine) lying to the west of the Brownsville anti- C.ine is another minor structure. Its sloves are very gentle and its b°ttom wide and shallow, tending to deepen to the south. The Bellevernon anticline, with its axis running through the tovm of that name, and extending to the southeastern part of Creene County, is a pronounced and an important structural feature. ‘here the anticline crosses the Monongahela at Charleston, the Pittsburgh coal is 1,000 feet above sea level. Both slopes of the anticline are gentile. The Waynesburg syncline is an unimportant structural feature lying west of the Bellevemon anticline. The amity anticline is the next structure to the west. It tails out Soon after entering the covnty and its flanks are not well de- fined. .The elevation of the Pittsburgh coal on the axis varies between 420 and 460 feet above sea. The Nineveh syncline, which lies to the west of the Amity anti- cline, is one of the deepest in the ippalachian coal basin, and has a well Gefinea axis. The southeastexrn slove of the syncline is irregular and the steepest dips are in the vicinity of the town of Nineveh. Further to the south the dips are gentle. On the western flank the rocl:s rise abruptly to the Washington anticline. The Washington anticline crosses the extreme northwest »vart or the county. The divs are steep on the southeastern flank, averaging about 100 feet per mile, with she excevdtion of that part lying be- tween Graysville and Bristoria, where the dip locally increases to 200 feet ver mile. 4 roughivy triansv lar come hes its center near Jacksonvillg. Further north the axig rises again. STRATIGRAPHY. Greene County is geologically the highest voint in the western part of the State because it contains higher beds in the Greene forma- tion than anv other county. The Greene and “ashington formations of Permjsn age awd the Monongahela formation of the Pennsvivanian series of the Carboniferous constitute the outcroppins bedrocks. Deposits of gravels, clays and sand of Ouaternary age occupy the valley bottoms. The Greene formation covers large areas in the county and is chiefly composed of easily weathered sandstones and shales. The upver vart of the formation has been removed by erosion. That which remains is about 800 feet thick. The ‘/Jashington formation which lies beneath it has not undergone much erosion. It is composed chieflv of Sandstones, shales and coals and hes a maximum thickness of 400 feet, Ral ri ad Oa ah anes Ay ‘ ¢ 4 Pee fis . j : wat eh j 7) 4 ye ' “ha My * + y : +) A} | acy . : ine Mi ‘ya i ; * ' ¥ ; shane Re we au i } | ace rai t af | * Py k i ‘ ve $y Lyi ary oa “eye Viv n" tere rate (ee i hana Roe nna tee ett a om : “ r ; j eT hint "4 Ns AMAL i a oe 4) pa. ‘4 ‘ ae Haire! of eyile | RRA PNR OR Ae ‘ ' r 4 : aA an aT : me, ws So ne y ‘ fy ‘ » tidy Oe. ~~ yr bv 9 . \ ‘ ' A ; s We UF . ee “aaa 5 “ Ah Ad dat ig ‘ v\ vo Ry 6 aN ern voy a. te Tih \ ‘ ; hy wT | A SAY Avs » Where 0 ei ia Nf " ; AFTRA wp i Pin ih Yahi de, abe ADS TAR ONG Shaved Waa, ay t Merle \ i ; " , od med) ee , Ah . vy Di ae n ? t ‘ { ‘ i hy is De Mt y Ayre Mg 4 ye ® yd! r eye eat 4 } ey R ; , H Ce ! a. iA arbies | iri i " ; i a 4 : , ah dy Ab Pie ie ad apt | : my f 4) aks Vee fi i J ae.

It con- tains shales and sandstones, over 100 feet of limestone, and five coal beds which are locally workable. The lower formations are known only from drill records and little definite knowledce is to be had concerning their character. COALS. Greene County contains the conls highest in the Carboniferous system in Pemsylvania. Thirteen coals outcrop in the county, of Which eight are locally workable and the others are thin and unim- portant. 1 coal bed that lies between 625 and 720 feet below the Pittsburgh coal and has been encountered in many drill holes, is tentatively correlated with the Upver Freeport coal which, in eastern VYashington County is 600 feet below the Pittsburgh coal, Pittsburgh Coal. The Pittsburgh coal outcrops along the valley of lionengahela River and its tributaries in the eastern part of the county. It outcrops along Ten Mile Creek nearly up to ‘Jaynesburg; up Muddy Creek for four miles and up Whiteley Cree for eight miles from the river. The Pittsburgh coal is probably workable everywhere in Greene County but it doubtless varies in thickness. It has good cokine qualities and during recent years has been bought up by large iron companies as a reserve for the future production of coke. This coal is cheracteristically a double bed, having a roof division separated from.a lower division by a clay parting from + inch to 3 feet thick. In the northern part of the county especially, @ root snale 8 to 12 inches thick comes in over the upper division of the bed. The roof division of the coal varies from 2 inches to 8 feet in thickness and is cut by many clay partings. The coal of the roof division is verv high in ash and sulphur, The lower and mineable division of the bed varies from 3 inches to 9 feet in thick- ness, including three persistent partings. These thin s.rtinss Sevarate the lower division into four distinet benches; the upper or "Breast", the "Bearing-in", the "Rrick", and the "Lower Bottom". The "Breast" coal is generally the best and thickest vart of the bed and in this county is free from any distinct impurities. The "Bearing-in" bench is usually-2 to 4 inches thick with a thin bone binder above and below it, and is so soft that the miners use it to bear in on the other coal to gain a working face. The coal is so Soft that it mines out as slack. The "Brick" coal is so namec because the cleavage planes tend to make it break and mine out in brick-shaped bloeks. As a rule, the "Brick" coal is of excellent quality although locally it is impure and not mineé. The "Lower Bottom" is the lowest bench of the lower division. It is generally very impure and carries numerous shale nartings.* In vnlaces, however, a few inches at the top is good clean coal and iS mined with the Seeack” com. . The roof division of the Pittsburgh bed thickens and the lower division thins to the north: The characteristic binders are every- where present. In Dunkard, Monongahela and Jefferson townships the exposures of the Pittsburgh coal show a‘thin top division and 4a ee ae CAT 2 al $ i yet abs ce sh pa rh ke “pane ’ ti an Ry, iv, GTN ca Sia ea Fag 9 nts iN ry “4 7 uy, Tabet & bea : ‘ ' Baye f [ 4 } ae i, % 4 ) { ty me me, aie site vw ahs a Ny ra "7 th ? ee art 64) tii ane LS NCR ACPA mb 20 SAU GRRE 2 he 808 ah A Daher eee TTI a (Sos 2 RM NR ENT RE 8 a rel ee ML Oe me woe rn diate eae Py enys hen ‘ y \ « We 0 ra » nN | SoC RI BS Sd Ten CPR NDE ALS dail ba z Loh wey fad er he : ai! _ ’ “ Bs oF .

In southern Greene County near the State line this coal measures 7 feet with $+ inch of slate 6 inches above the bottom. On Dunkard Creek the bed is 11 feet thick with a clay parting 8 inches above the bottom. At Greensboro the roof and main clays are each 1 foot thick; the lower division of the coal is 9 feet thick with benches of 6, l and 2 feet. The partings are very thin. The coal appears to be thinnest at the mouth of Cheat River. Redstone Coal. This bed which lies 50 feet above the Pitts- burgh coal is persistent in the county but rarely is mineable, its average thickness being less than 18 inches. Its horizon is often marked by black shale carrying a few inches of coal. Along Mononga- hela River the bed is represented by 13 feet of bituminous shale, While in the districts back from the river the bed is a few inches of clean coal, \ Sewickley Coal. The few outcrops of the Sewickley coal are confined to Si eastern part of the county where it is mined chiefly in the vicinity of Maple town} hence its local name, the Mapletown coal. In this locality the’ coal varies from 4 inches to 5 feet 6 inches in thickness. At Grays Landing the bed is in two 2 foot benches separated by 1 foot of slale. At Hartleys Mills the coal is thicker than at Grays Landing, but is cut by many clay partings. The top and middle benches are fair coal, but the lower bench is dirty and carries much sulphur. Below Clarksville on Ten Mile Creek the coal is 12 to 20 inches thick and carries 1 to 3 partings. The coal makes its best Showing at -Mapletown; where it is divided into three benches of 2 feet 3 inches, 4 inches, and 2 feet 6 inches, parted by clay binders 1 to 2 feet thick. It lies about 120 feet above the Pittsburgh coal. ~Uniontown Coal. This bed, lying from 60 to 90 feet below the Waynesburg coal, is not mined because it rarely exceeds 1 foot in thickness. Its blossom is persistent, but in many places the horizon is marked by bituminous shale, Waynesburg Coal, The most important bed above the Pittsburgh is the Waynesburg coal. It is the main source of domestic fuel in many localities yet the quantity mined is small in comparison with the output of Pittsburgh coel in the county. Its position 400 feet above the Pittsburgh coal makes the outcrop more widespread and accessable, for it extends up South Tork of Tenmile Creek toward iJaynesburg, up Whiteley Creek, and along Dunkard Creek and Meadow Run, In the Fastern part of the county the ‘Jaynesburg coal is 5 to 9 feet thick. In most localities it is a double bed. The upper bench varies from 1 to 3 feet and the lower bench is from 2 feet 6 inches to 4 feet in thickness. The benches are sevarated by a clay and shale parting having a thickness of 3 inches to 2 feet 4 inches. The coal is hard, but contains a large percentage of ash and sulphur. On Tenmile Creek the bed is 4 feet 11 inches thick, of Wiich 1 foot 5 inches is clay. At Jefferson it has a thickness of 7 feet 8 inches, with two clay partings totalling 1 foot 6 inches, 4t Clarksville it is 6 feet 4 inches, with two clay vartings of 5 and 14 inches, On Big Whiteley Creek the beé is 4 feet 11 inches thick and carries two 2 inch clay partings. eh + Digitized by the Internet Archive in 2022 with funding from University of Illinois Urbana-Champaign Alternates httos://archive.org/details/coalbedsingreeneOOsisl_ 0 The Waynesburg "A" and the little Washington coals are thin beds which are represented in most localities by a few feet of bituminous Shale. Washington Coal. This bed is the most persistent of the Dunkard coals and although it has small importance in Greene County where it rarely reaches mineable thickness, it is one of the important coals in \iaashington County. In Greene County it is much swollen by clay and bone pbartings and is irregular in thickness. Over large areas the bed is represented only by bituminovs shale. This coal lies 140 to 180 feet above the ‘Jaynesburg coal. Jollytowm Coal. This bed is minec locally for domestic use in the Dunkard Creek region where it has a maximum thickness of 20 inches. [ts average thickness is less than 1 foot. It outcrops in a number of places along the south fork of Tenmile Creek, on Browns Creek and on Overflowing Run, There are several small coals in the upper part of the Greene formation that nowhere exceed a few inches in thickness and are not mined. They are of geologic interest only and are not described in this brief bulletin. They are, in ascending order, the Tenmile, Dunkard, Nineveh, and Windy Gap coals. UNIVERSITY. OF ILLINOIS-U iN ——
