Willman SUMMARY In 1931 "the Illinois State Geological Survey published Report of Investigations No. 23, on "High-calcium limestone near Morris, Illinois," based on data obtained from surface outcrops and records of water wells. The potential commercial importance of the deposit to- gether with requests for further information and the acquisition of information not known to exist at the time of publication, em- phasized the desirability of coring the deposit. Through the courtesy of the State Highway Division four borings with a dia- mond drill were made for the Geological Survey. Each boring passed through the limestone and entered shale. The results of the borings and the chemical analyses of the cores are shown in Table 1. They indicate that in the tract south of Illinois River the upper few feet, to a maximum thickness of k- or 5 feet, is usually high-calcium stone, most of it brown in color. This confirms the information obtained from outcrops. Below the high-calcium rock the amount of magnesium carbonate generally increases with depth. All samples of core tested had a high or moderately high total carbonate content. BORING UO. 1 Boring No. 1 was located 60 feet east of the Elgin, Joliet and Eastern Railroad and ^0 feet north of a small aban- doned quarry about a quarter of a mile north of the grain eleva- tor at Divine station,' sec. jk, T. ^ N. , R. 8> E. Black soil H- inches thick overlies the limestone. No core was obtained from the upper foot of the stone which was partly disintegrated but otherwise appeared to be similar to that immediately underlying. The two samples of core represent- ing the next 3 feet 9 inches of stone contained respectively 93.1 and 97*0 per cent CaCO? and 1.7 and 2.7 per cent MgCO?. ■ aiCP'I.: ■• -...:.;' ; V < ■'". .

At this location the strata penetrated were 13 inches of soil overlying 2> feet k- inches of limestone below which blue shale was encountered. Analyses of the core indicate the entire thickness of stone to be magnesian. The upper 5 feet 1 inch contained 35*3 P er cent MgCO^ and the lower 3 feet 3 inches contained 15. 7 per cent MgC0 T . '3 DISCUSSION The stone encountered, in boring No. 1, almost 29 feet thick, was somewhat thicker than anticipated, on the basis of previous data. The rock in boring No. 2, 26 feet thick, was somewhat less than was expected on the basis of the reported 32 and kk feet of stone encountered in water wells drilled respec- tively west and east of it. Boring No. 3 with 26 feet of stone gives information in an area where no data were previously avail- able. The g> feet of stone encountered in boring No. k on the north side of the river was much less than anticipated, as a well about a third of a mile northeast of the boring reported 36 feet of stone. The fact that only the upoer part of the deposit is high-calcium limestone restricts its use. The deposit would prob- ably make satisfactory agricultural limestone. The stone below the high-calcium portion may be suitable for concrete aggregate, for road material, for certain types of mineral filler, for rip- rap, rubble, and building stone but further exploration of the deposit on a larger scale and testing of large samples would be necessary to determine its acceptibility for these uses. The commercial feasibility of working the deposit so as to separate the upoer high-calcium rock from the underlying magnesian beds is not known. The cores indicate that most of the high-calcium stone is buff or brown. It could probably be em- ployed for those uses, as listed in Report of Investigations No. 23, which are not critical with regard to the color of the stone or its content of iron compounds. The data afforded by the cores and their analyses in- dicate the variable nature of the deposit and confirm the recom- mendation made in the previous publication that it be thoroughly prospected before development is undertaken. .7- . -.M-:- f ft* -•■: . •v l.„ ■•,., ;> k & ■■.- •••;■.•■'■ -.■"■ : ' ■'■ .'

In order to secure the maximum information re- garding the chemical composition of the rock, it was necessary to divide some of the core at points whose exact depths were not known. In these cases it was assumed that the core was uniformly distributed throughout the interval which it represents and the resulting thick- nesses are given in parentheses. (2) Chemical analyses were made by the Analytical Division, State Geolog- ical Survey. In order to expedite preparation of this report a rapid method of analysis having an accuracy of i 0.5 per cent on the basis of oxides, equivalent to approximately * 1.0 per cent on the basis of carbonates, was employed. Each analysis is the average of duplicate determinations calculated to the first decimal place. The accuracy of the analytical method is comparable to the probable ac- curacy of sampling.
