INCLUDING ROCK TYPE AND SURFACE CONFIGURATION

by Eva B. Kisvarsanyi

ABSTRACT

Data from 545 drillholes in 54 Missouri counties are tabulated to show rock types and configuration of the buried Precambrian surface. Listings also include the drilling date, owner, collar elevation, depth to the top of the Precambrian, total depth, penetration, elevation, type and availability of Precambrian samples and the number of thin sections prepared. An accompanying map shows the configuration of the Precambrian surface at a scale of 7: 7,000,000.

INTRODUCTION

Information relating to the buried Precambrian surface in Missouri is presented in this report. Data from 545 holes drilled to Precambrian basement as of January 1, 1973 are tabulated by counties, in alphabetical order. A map showing the configuration of the Precambrian surface at a scale of 1:1, 000, 000 is also included.

The Precambrian basement had important influence on Paleozoic and younger sedimentation and structures. Discovery of high-grade iron ore deposits i.n buried Precambrian rocks, and of Mississippi Valley-type leadzinc-copper deposits in over lying Upper Cambrian strata in southeast Missouri focused increased attention to the basement complex. The number of drillholes to Precambrian multiplied during the last 15 years, and revision and updating of earlier basement maps (Adams, 1959; Hayes, 1962) became necessary. Within the scope of the

DNR, Geological Survey's Operation Basement program, established in 1968, drillhole data were compiled on a statewide basis, basement maps were prepared, and core samples were collected for petrographic studies (Kisvarsanyi, 1974). The data will be utilized in current and continued studies relating to Precambrian structure, mineralization and geochronology.

The extensive subsurface log file of the DNR, Geological Survey and logs released by the U. s. Forest Service and the Missouri Conservation Commission were the major sources of data. Mining and exploration companies in Missouri provided additional valuable information through release of exploratory drillholes and core material that would otherwise have remained inaccessible. Their cooperation has greatly contributed to make the list of drillholes as comprehensive as possible, and is thankfully acknowledged.


EXPLANATION OF TABLE

Drillholes are listed by counties, in a lphabetical order. Each Missouri county is assigned a county code letter (s), and each drillhole is assigned an Operation Basement Number (0. B. No.) consisting of the appropriate county code letter (s) followed by a munher. Drillholes within each county are listed in numerical order.

It would have been desirable to list drillholes in geographic order in each county to facilitate map reference. This could not be strictly adhered to for the following reasons. The comprehensive program of compilation of drillhole data, collection of Precambrian rock samples, and preparation of petrographic thin sections was begun in 1969. From the beginning it was necessary to use a numbering system that is permanent for each drillhole and that can be used for labeling both corresponding rock samples and thin sections. Holes drilled or data released during the period 1969-73 would necessarily have to be added to the list in chronological order. The Operation Basement numbering system has the advantage that it is expandable, any future drillholes being added to the list without the necessity of renumbering each well and relabeling corresponding samples and thin sections, and that the use of county-code letters gives a geographic reference to the location of drillholes within the state.

The standard format for the description of the location of drillholes

2

has been modified in order to save space for the columnar presentation of data. The order of numbers in the second column is township, range, and section. As all Missouri townships are north of the reference base line, the customary designation has been shortened to the township number only. This is followed by the range number east (E) or west (W) of the Fifth Principal Meridian, then by the section number. Fractional quarter subdivisions of the section are indicated by the letters ~ for NE!, Q for NW!, .£ for SW!, and s_! for SE!, and the order is from largest to smallest, the reverse of the usual order. Therefore, the location of a drillhole customarily given as SE! NE! SW! sec. 24, T. 32 N., R. 3 E., reads 32-3E;24cad in the tabulation.

If a log of the sedimentary section is available, the location is followed by the DNR, Geological Survey log number. This is followed by the owner's name and number; those marked by an asterisk (*) are withheld at the request of the owners. Subsequent columns indicate the year drilling was completed, if known; the elevation of the well datum as ground level determined by surveying or estimated (E) from topographic maps; depth to the top of Precambrian surface; total depth of the well; thickness of Precambrian rock penetrated in the drillhole; and elevation of the Precambrian surface relative to sea level. The last five data are expressed in feet.

The final three columns contain information pertaining to the Precambrian samples, thin sections, and rock type(s) in each drillhole. Under the heading "Spl. " the following code letters are used to indicate the type and availability of Precambrian samples:

CRW - Core of entire Precambrian section stored in the DNR, Geological Survey warehouse.

CRC - Character samples of Precambrian core are on file in Operation Basement core library.

CT - Only churn or rotary drill cuttings, or core chips of comparable size are available for study at the DNR, Geological Survey.

NS - No samples are on file at the DNR, Geological Survey.

D - Driller's log, no samples are available anywhere.

In the column with the heading "TS" the number of thin sections prepared from Precambrian cores or cuttings in each drillhole is indicated. The thin sections are on file in the DNR, Geological Survey Operation Basement Thin Section Repository. Both character samples and corresponding thin sections are labeled with the appropriate Operation Basement number of the respective drillhole, followed by the depth of the sample.

Correct determination of the Precambrian rock type (s) encountered in each drillhole depends to an immeasurable degree on the type of samples

Explanation of Table

available for study. During the past 15 years the majority of basement holes in the list were core-drilled. Because of the excellent cooperation of mining and exploration companies involved, the writer was able to log the Precambrian section of many cores saved by the owners and to obtain character samples for petrographic study. In some cases the entire Precambrian core was donated to the DNR, Geological Survey. Core logging the penetrated section, combined with petrographic description of thin sections, is the most reliable basis for rock-type determination.

The quality of churn and rotarydrill cuttings is variable. Some consist of cuttings chips large enough to be suitable for preparation of thin sections and for the determination of textural relationships of the component minerals. Others are too finely ground to be of much value for petrographic study. Cuttings on file at the DNR, Geological Survey from older deep basement wells were examined under the binocular microscope. Thin sections prepared from these samples by former staff members of the Missouri Geological Survey during the 1930's and 1940's, by Skillman (1948) and by Adams (1959) were examined by the writer. Basement samples from more recent churn and rotary drillholes were also examined under binocular microscope, and thin sections were prepared from samples suitable for this purpose. Petrographic descriptions and classification of Precambrian rock types as indicated in the list are those of the writer; in some cases they disagree with ear lier descriptions by others (Skillman, 1948; Adams, 1959; Denison, 1966).

If no Precambrian core samples were available for study, the rock type

indicated in quotation marks was taken from company and/ or Forest Service logs. Rock types indicated on old driller's logs are also in quotation marks.

In the vicinity of Precambrian outcrops in southeast Missouri, particularly in Iron, Madison, Reynolds, St. Francois, Shannon, and Washington Counties, numerous private water supply wells and closely-spaced, shallowexploration holes were drilled to basement. Rock types indicated for these

drillholes are from the DNR, Geological Survey logs and corresponding samples were not studied by the writer. The term "porphyry" frequently was used on these older logs to distinguish igneous rocks of extrusive origin with a porphyritic aspect from intrusive rocks. A phanitic igneous rocks were usually logged as felsite. Although use of the term "porphyry'' as a rock name is not advocated by the writer, it was retained in order to agree with existing usage on DNR, Geological Survey logs.
