Part 2--Mineral Resources of Chase County

by Howard G. O'Connor, John Mark Jewett, and R. Kenneth Smith


The known mineral resources of Chase County comprise oil in the southeastern part, gas in the central and northwestern part, and deposits of limestone, clay (shale), gravel, sand, and silt. Ground water, also an important mineral resource, is discussed separately in Part 3 of this report. Limestone, gravel, and sand have been exploited for many years but extensive reserves remain. Oil and gas have been produced for several years, but rocks below those of Pennsylvanian age have been inadequately explored for petroleum. Clay resources have been utilized to a very small extent or not at all.

An economic geologic map of Chase County is given in Plate 2. Locations of active and inactive pits and quarries and the names of exploited stratigraphic units and some important test data on limestones and clays (shales) are shown on the map. Locations of all wells that have been drilled for oil or gas for which any information is available also are indicated. The map shows the lowest stratigraphic depth reached and the present status of all wells. Areas of oil and gas fields and locations of roads, railroads, oil and gas pipelines, and pumping stations are indicated.

Economic Geology of Outcropping Rocks

Properties and the sequence of limestones and shales that crop out and surficial deposits of gravel, sand, and silt are discussed in Part I of this report. Their distribution is shown on Plate 1.


Several limestones occurring in the exposed portion of the geologic column are of economic importance because of their thickness and qualities. The more common uses for which these rocks are suitable include concrete and other aggregate, crushed rock for road metal and other uses, agricultural limestone, riprap, and building stone. Some of them, because of chemical composition, may be suited to more specialized uses. Chemical analyses of rock taken from the more important ledges are listed in Table 1. Data on limestone quarries are listed in Table 2.

Agricultural Limestone

Limestone having a calcium carbonate equivalent of 80 percent or more occurring in ledges sufficiently thick to allow economical quarrying is regarded as potential material for agricultural limestone. Physical requirements for agricultural limestone largely are dependent on processing and are not considered here.

Limestones that are potential sources of agricultural limestone include: Herington, Cresswell (locally), Towanda, Fort Riley, Crouse, Cottonwood, a limestone in the lower part of the Eskridge shale (locally), Neva, Glenrock, and Long Creek.

Because of the chert content in the Florence, Shroyer, and Threemile ledges, these rocks are not regarded as sources of agricultural limestone.

Dolomitic limestones, such as the Herington and Long Creek, are of special interest as sources of agricultural limestone because they meet minimum requirements for calcium carbonate equivalent of 80 percent or more and have other desirable properties, namely (1) a slower rate of neutralization and (2) they supply soluble magnesium which is now known to be beneficial to plant growth. The Cottonwood limestone, a limestone in the Eskridge shale, and the Neva limestone have been utilized for agricultural limestone in the county.

Building Stone

Nearly all the thicker and more massive limestone ledges in Chase County have been used as sources of building stone. Although rough dimension blocks can be obtained from all of them, the Fort Riley, Cottonwood, and Americus limestones are especially well adapted for cut stone. Other limestones regarded as possible sources of rock for building stone include parts of the Towanda, Kinney, Funston, Crouse, Neva, and the Glenrock limestones. Factors considered include durability, thickness of ledges and individual beds, spacing of joints, and color on weathering.

The principal uses of the limestones regarded as of minor importance as building stone are for construction of local bridge foundations and abutments, foundations for small buildings, and in construction of farm buildings and other relatively small structures.

Fort Riley limestone.--The Fort Riley limestone has not been quarried extensively in Chase County, but is an important source of material for cut stone in Cowley and Geary counties. Parts of this rock are light and uniform in color, uniform in texture, easily cut, and have bedding and joint planes spaced to allow quarrying of large blocks. The durability of the Fort Riley limestone, taken from elsewhere in Kansas, has been demonstrated in many buildings.

Cottonwood limestone.--The Cottonwood limestone for a long time has been an important source of building stone. Early in the century six or more commercial quarries produced cut stone in Chase County (Prosser and Beede, 1904, p. 5). The rock is massive, nearly white in color, even-textured, durable, and commonly remarkably free from jointing. Blocks of stone 3 feet or more thick and of much greater length and width can be taken from the ledge. The crushing strength is reported as 6,800 pounds per square inch, the weight 161.6 pounds per cubic foot, and the specific gravity 2.59 (Prosser and Beede, 1904, p. 5). One commercial quarry is now operating in the county about 2 miles east of Cottonwood Falls.

Americus limestone.--The lower part, or "main ledge," of the Americus limestone is regarded as a potential source of commercial building stone because of properties that allow quarrying of large blocks uniformly about 1 1/2 feet thick. The rock is gray in color and has no tendency to become slabby after long exposure.

Crushed Rock and Riprap

All the thicker limestone ledges in Chase County are potential sources of rock for crushing and for riprap material. Many have been used for road metal or aggregate material. No recommendations of individual ledges for aggregate material are made because of the many current sets of specifications for aggregate for specialized uses and because no physical tests were made.

Wreford limestone.--The importance of the Wreford limestone as a source of crusher rock has been recognized for many years. According to Prosser and Beede (1904, p. 6): "This rock [Wreford limestone] was extensively quarried for ballast at the Crusher Hill quarry, one mile northwest of Strong." Chert in the Wreford and Florence limestones may cause them to be undesirable for crushing or for some uses.

Other limestones.--Other comparatively thick limestone ledges that are important sources of road metal and crushed stone for other uses include the Herington, Cresswell, Towanda, Fort Riley, Funston, Crouse, Eiss, Morrill, Cottonwood, limestone in the Eskridge shale locally, Neva, Glenrock, Long Creek, Americus, and Five Point limestones. All the limestones mentioned in this section are regarded as potential sources of riprap material for various uses.

Ceramic Materials

Ceramic data from firing tests on several samples of clay from Permian shales and from Pleistocene alluvial deposits were obtained in the Geological Survey Ceramic Laboratory by Norman Plummer. Ceramic data are listed in Tables 3 and 4. The paragraphs below were prepared in part by Plummer.

Clay for Structural Products

Most of the shales have a very short firing and maturing range when being made into brick or other ceramic products because of their high content of lime. The lime content, however, has the property of neutralizing red colors of iron oxides, and buff and greenish colors are produced. Data (Table 3) indicate that brick and tile can be produced from the Florena shale if the firing temperature is controlled to within 30°F of cone 1 (about 2100°F). The Blue Springs shale also is usable for making brick and tile but an even closer control of firing temperature is necessary. Other shales that were tested are unsatisfactory or of doubtful value for structural clay products (Table 3).

A ceramic analysis was run on a composite sample of 18 feet of alluvial clay from the bank of Cottonwood River, NE NE sec. 35, T. 19 S., R. 8 E. (CS-15). It was first tested by mixing with water and extruding from a de-airing brick machine (CS-15). Working properties were excellent, but cracks formed in the bricks in drying. The clay was then mixed with 15 percent river sand for one test (CS-15-5) and was preheated to 600°F before forming into bricks for another test (CS-15-C). In both cases the working characteristics were good and no cracking occurred in drying. Results of the tests are given in Table 4. The color after firing ranged from orange red to brick red and the clay proved satisfactory for use in any type of structural clay product. The firing range of about 120°F is sufficiently long. At the maximum temperature attained in the test (2030°F), there were no symptoms of overfiring. The low saturation coefficient of the fired sample indicates that the brick or tile made from the clay will withstand severe weathering (Table 4).

Shales for Ceramic Concrete Aggregate and Railroad Ballast

Several tests have been made on Permian shale samples to determine their suitability for use in the production of a sintered railroad ballast (ceramic slag) by means of heating to a high temperature in a rotary kiln (Plummer and Hladik, 1948). The same shales were used in these tests as for the regular ceramic tests reported in Table 4. Sample CS-5 which proved to be best for brick and tile was also best for railroad ballast or heavy concrete aggregate manufacture. Samples CS-10, CS-13, and CS-38 also are satisfactory raw materials for the manufacture of these products, but should be ground, mixed, and pelleted before firing in order to eliminate slaking of calcareous portions (Table 5).

Subsequent tests on the same materials in an attempt to produce a lightweight concrete aggregate similar to Haydite indicate that a bloated shale product cannot be manufactured from these Permian shales by the rotary kiln method, but that any one of the various sintering or moving-hearth methods is well adapted to materials like the Florena and the Roca shales (Plummer and Hladik, 1951).

Material for Rock Wool

Although no specific tests have been run with Chase County samples, a number of Permian shales proved satisfactory for the production of rock wool in a series of tests run several years ago (Plummer, 1937). Sample CS-14-B, from the Gage shale included in this report, is sufficiently calcareous to produce a rock wool without additions. The Grant shale as sampled in Cowley County and also in Riley County is a natural wool rock (a wool rock is defined as a rock having a composition such that no additional material need be added to prepare it for processing into rock wool). Rock wool produced from the Cowley County sample was excellent in quality. Parts of the Eskridge and Holmesville shales are sufficiently calcareous to be classed as wool rocks, but in general small additions of limestone would be necessary in order to increase the fusibility. A material suitable for the production of rock wool should have a calcium carbonate plus magnesium carbonate content of 50 to 65 percent. The balance should consist largely of silica, with some alumina and other oxides. Usually a shale having an ignition loss ranging from 22 to 30 percent can be used for the production of rock wool.

Gravel and Sand

Extensive accumulations of chert gravel together with chert and quartz sand occur in the terrace deposits and alluvium in the stream valleys. One washing and screening plant which utilizes terrace deposits of sand and gravel is located north of Bazaar along the Atchison, Topeka, and Santa Fe Railway.

The locations of the Bazaar and other pits, most of which are operated intermittently, and the disposition of gravel deposits of commercial importance are shown on Plate 2; the materials are described in Part 1 of this report. The reserves of gravel and sand in Chase County are large.
