On the Geology of the Western States of North America, 0000, Owen David Dale,

The remarks here submitted will be confined chiefly to that part of the Western States of North America watered by the rivers Ohio, Wabash, Illinois, Rock, Wisconsin, Cumberland and Tennessee, lying between the 35th and 43rd degree of N. latitude and the 81st and 91st of W. longitude. The district includes the states of Illinois, Indiana, Ohio, Kentucky, Tennessee, and the Du Buque and Mineral Point districts of Iowa and Wisconsin. This territory occupies an area of about half a million of square miles, but its geological features are remarkably uniform, belonging, with a few partial exceptions, to the periods of the bituminous coal and carboniferous limestone as found in Europe, and the Silurian rocks as described by Sir R. Murchison; the exceptions are the superficial deposits which occasionally cover up these from view over considerable tracts, and these must either be referred to the age of gigantic mammalia and formations of a much newer date, or belong to a marl and greensand found in the western district of Tennessee, probably a portion of the greensand and other members of the cretaceous group. A general idea of the geological formations of the whole tract may be obtained from the annexed diagram. ... This 250-word extract was created in the absence of an abstract

Breccia and Pennsylvanian cave filling in Mississippian Saint Louis Limestone, Putnam County, Indiana, 1961, Smith Ned Myron, Sunderman Jack Allen, Melhorn Wilton Newton,

A limestone breccia and several bodies of shale and sandstone in Mississippian St. Louis limestone were discovered in a quarry opened during the summer of 1959 in the SE1/4NW1/4 sec. 15, T.15N., R.4W., Putnam County. A small mass of sandy limestone conglomerate overlay part of the breccia. Nearly all these bodies have been removed in quarrying. The breccia and the shale-sandstone masses appear to have originated from 2 separate geologic processes which occurred at 2 different times. The origin of the breccia is in doubt because not enough critical evidence is available to prove conclusively and single origin. The authors believe, however, that the breccia probably is the product of a submarine rock slump during St. Louis time which was triggered by the tectonic activity that initiated early movements along the Mt. Carmel fault. Other possible origins, such as solution of evaporites accompanied by collapse of overlying rock or formation of caves in a karst terrain followed by roof collapse, are not supported by the evidence observed. The shale-sandstone bodies are believed to be rocks of Pennsylvanian age which were deposited in caverns developed during the Mississippian-Pennsylvanian erosion interval. The limestone conglomerate is probably of the same age as the shale-sandstone bodies

Distribution of Indiana cavernicolous crayfishes and their ecto-commensal Ostracods., 1975, Hobbs Iii Horton H.

Six species and subspecies of crayfishes and four species of entocytherid ostracods are known to inhabit the subterranean streams of southern Indiana. Cambarus (E.) Iaevis (troglophile) appears to be the most widely distributed crayfish and occurs in both karst areas within the State. The troglobite, Orconectes inermis (2 subspecies), is restricted to the larger karst area in solution cavities of Mississippian carbonate rocks. The remaining crayfishes, Orconectes immunis, Orconectes propinquus and Orconectes sloanii, are not common inhabitants of cave waters and are probably trogloxenes. All of the crayfishes except O. sloanii were found to host at least one species of ostracod. From data presented, Sagittocythere barri might be expected to be found commonly in association with Orconectes inermis, Donnaldsoncythere donnaldsonensis, Uncinocythere xania and Dactylocythere susanae, however, are more commonly associated with C. (E) laevis, indicating a near host-specific relationship among these taxa. Whether these are host-specific associations or ones imposed by certain ecological parameters will require additional investigations. Although a fair understanding of the distribution of these crustaceans in the larger, Mississippian limestone belt has been obtained, additional field work on the perimeter of the spelean ranges of the several species will probably prove productive. Furthermore, considerable cave exploration and biospeleological surveys are needed in the Silurian-Devonian limestones of southeast Indiana before our knowledge of these crayfishes, entocytherids and other cave-dwelling species approaches that for the Mississippian karst of the State.

Seasonal changes in a population of Pseudanopthalmus tenuis (Coleoptera, Carabidae) in Murray Spring cave, Indiana: a preliminary report., 1975, Keith James H.

A study of a population of Pseudanophthalmus tenuis is being conducted in Murray Spring Cave, Orange County, Indiana as one facet of a larger research project encompassing the entire terrestrial community of that cave. Changes in behaviour and abundance determined by census and mark-recapture methods and physiological changes determined from field-collected beetles indicates that these animals exhibit a seasonal reproductive rhythm probably mediated or controlled by winter and spring flooding of the cave.
