The Karst Of Transvaal (South Africa), J. Martini, I. Kavalieris

International Journal of Speleology

The Transvaal Karst is a world important example of a Karst developed on a very old dolomite. Its unique character is due to the composition of the rock and history of development. The dissolution of the dolomite is interesting and has an important effect on the character of the caves developed. The caves preserved in this area include the longest known in South Africa and are perhaps among the largest dolomite systems known in the world. They are very old and in some cases contain important palaeontological deposits (Australopithecine fauna). The caves to various degrees are in a state of …

Sur Les Bathynella De Roumanie: B. (B.) Boteai Serban, B. (B.) Vaducrisensis N. Sp., B. (B.) Plesai Serban Et B. (B.) Motrensis Serban (Bathynellacea, Bathynellidae), Deuxième Partie, Eugène Serban

International Journal of Speleology

In the second part of the note a discussion is given dealing with the importance of different characters in the systematics of the genus Bathynella Vejdovsky and with species individualisation in the sub-genus Bathynella (Bathynella) Vejdovsky. We emphasize the differentiation of some elements of the VIIIth male pereiopodes, these appendages never having the same morphology in different species. Taking into account the structure of the apical end of the pennian anterior plates, we suggest to group separately boteai with vaducrisensis and plesai with ruffoi. The main conclusions of the recent studies on the European Bathynella are also given.

La Léthargie Chez Les Chiroptères Cavernicoles D'Afrique Centrale, Michel Anciaux De Faveaux

International Journal of Speleology

From his personal research undertaken in the subterranean field (natural and artificial cavities) in Shaba (ex-Katanga, in S.E. Zaire) and Rwanda, the author briefly defines the macroclimate of the prospected regions as well as the microclimate of the subterranean habitat (humidity and temperature). A reversible hypothermia has been noticed in the dry season only (from May till August) in eleven species of troglophile Chiroptera belonging to the following families: Rhinolophidae (7 species of Rhinolophus), Hipposideridae (only Hipposideros ruber) and Vespertilionidae (Miniopterus inflatus rufus, Miniopterus schreibersi arenarius & M.s. natalensis, Myotis tricolor). No sign of lethargy has …

The Effect Of Cave Entrances On The Distribution Of Cave-Inhabiting Terrestrial Arthropods, Stewart B. Peck

International Journal of Speleology

Populations of cave invertebrates are generally considered to be food-limited. The cave entrance is a major source of food input into the community in the form of decaying organic matter. Thus, the densities of scavenging terrestrial cave invertebrates should be related to the distance from the cave entrance because this represents a measure of food abundance. A test showed this expectation to be true in Crossings Cave, Alabama. A population density peak occurred 10 m inside the cave where the dark zone and detritus infall regions meet. The greatest population peak occurred at 100 m where densities of crickets and …

Les Adaptations À La Volvation Du Squelette Externe De La Tête Chez Caecosphaeroma Burgundum Dollfus, Crustacé Isopode Des Eaux Souterraines, C. Marvillet

International Journal of Speleology

The study of the cephalic capsule of Caecosphaeroma burgundum, a subterranean waters Isopod, demonstrates improved adaptations to volvation; these concern in a similar manner the other regions of the body, particularly the pleotelson. From a primitive aquatic Isopod structure, the head of this blind Spheromid has been completely fashioned by many mechanical factors: posterior margin of pleotelson providing support on the head, relation of anterior angles of the second pereionit and, above all, the mandibular palps and antennae which retract into two deep grooves of the face. The comparative study of the head of other volvational Isopods shows the …

Geology, Mineralogy, And Fluid Inclusion Geothermometry Of The El Paso Gold Mine, Cripple Creek, Colorado, Charles Albon Lane

Masters Theses

"The Cripple Creek district consists of a deeply- eroded, breccia-filled volcanic subsidence basin. Subsidence of the basin occurred along fissures formed by fracturing during the Laramide orogeny. The material filling the crater probably developed first as fissure flows. Erosion of the volcanics formed the material now filling the basin. Volcanic activity was accompanied by intrusion of numerous sills, dikes, and stocks of several different rock types into the breccia and surrounding granite, punctuated by occasional explosive activity. The majority of the mines in the district lie within the volcanic center; however, a few important ones, most notably the El Paso …

Hydrologische Und Chemische Untersuchungen An Den Fließgewässern Des Schlitzerlandes. A. Quellen. I. Übersicht, Jörg Brehm

International Journal of Speleology

In a Triassic sandstone woodland (Schlitzerland in Hesse, Western Germany) 17 springs were hydrologically and hydrochemically investigated throughout one year (April 1973 - April 1974). Measurements were carried out on water volume, temperature, electrolytical conductivity, pH, aikalinity, chlorinity, dissolved molecular oxygen, dissolved organic material (COD), ammonia, nitrite, nitrate, and free phosphate. Among the hydrochemical factors investigated the pH-value was closely related especially to the micro-climate in the spring drainage area. In particular the pH rose both with increasing length of the drainage area and — within the same spring with decreasing water supply. On the other hand the pH-value diminished …

Sedimentology Of The Glaciofluvial Deposits Of Woolwich And Pilkington Townships, Ellis Bowes

Theses and Dissertations (Comprehensive)

The Lake Wisconsin glaciofluvial deposits in Woolwich and Pilkington townships are examined for the purpose of environmental reconstruction and the establishment of the paleocurrent patterns. Sediment grain size and primary sedimentary structure are used to define sedimentary facies of environmental studies while the distribution of indicator pebbles, trends in clast size reduction and primary sedimentary structures and employed for paleocurrent analysis. The exposures most representative of the depositional sequences encountered are examined and provide an impression of the sedimentological characteristics of the various glaciofluvial deposits.

Three distinctive types of glaciofluvial deposits can be identified on the basis of surface morphology …

Experimental Testing Program In Elementary Chemistry: A Preliminary Report, Billie G. Broach, Howard L. Hodges

Journal of the Arkansas Academy of Science

An experimental testing program is described which utilizes questions that are partly computer composed, in addition to a section composed by the instructor, and a retesting option to the student. Results from a trial of the program for one term indicate that (1) course grades were improved, (2) the student withdrawal failure rate was unaffected, and (3) the employed students took greater advantage of the retest than did the unemployed students.

Lower Mississippian Lithostratigraphy, Northern Arkansas, Walter L. Manger, Jack L. Shanks

Journal of the Arkansas Academy of Science

Lower Mississippian lithostratigraphic units in northern Arkansas are (ascending order) the Bachelor, St. Joe, and Boone Formations. These formations disconformably overlie Middle Ordovician to Upper Devonian strata and are overlain disconformably by Meramecan or Chesterian strata. The Bachelor Formation is generally a thin (less than 0.3 m), persistent, orthoquartzitic sandstone with common to abundant phosphatic pebbles overlain by a green silty shale. In northwestern Arkansas, the Bachelor Formation commonly lacks sandstone. The Bachelor Formation has been confused previously with the Sylamore (Upper Devonian) and older sandstone units. Although commonly regarded as a member of the Boone Formation, the St. Joe …

1974 Nonflood-Stage Chemical Loads Of The Buffalo River, Arkansas, Kenneth F. Steele, George H. Wagner

Journal of the Arkansas Academy of Science

Dissolved Ca, Mg, Na, K, Fe, Mn, and Zn loads of the Buffalo River generally show trends along the river attributable to changes in geology and vary with the season because of concentration by evapotranspiration and dilution by rain. Suspended material element loads show neither seasonal trends nor trends along the river. The Fe load for the river is predominantly in the suspended material, the Mn load is divided approximately evenly between dissolved and suspended material, and Ca, Mg, Na, K, and Zn are predominantly in the dissolved load.

Regional Carbonate Deposition Of The Pitkin Limestone (Chesterian): Washington And Crawford Counties, Arkansas, Robert E. Tehan

Journal of the Arkansas Academy of Science

The Pitkin Limestone overlies black shale of the Fayetteville Formation and is the youngest Mississippian unit in the Paleozoic succession of northwest Arkansas. Five major fades have been delineated within the formation by apetrographic examination of samples collected from 17 measured sections: (1) oolith facies, (2) bioclast facies, (3) nodular limestone-shale facies, (4) mudstone facies, and (5) lime mud mound facies. The distribution of these facies in the Pitkin Formation suggests that Fayetteville terrigenous sedimentation was succeeded by the deposition of widespread oolith shoals and skeletal blanket sand bodies across the northern Arkansas structural platform. Sparse accumulations of lime mud …

Algal-Bryozoan Carbonate Buildups Within The Pitkin Limestone (Mississippian-Chesterian), Northwest Arkansas, Alex T. Warmath

Journal of the Arkansas Academy of Science

More than 14 biohermal buildups have been recognized within the Pitkin Limestone (Mississippian-Chesterian) in eastern Washington and western Madison Counties, northwest Arkansas. These buildups resemble previously described algal mounds in upper Pennsylvanian strata of the Midcontinent region, but differ in their faunal and floral constituents. The mounds are composed of calcilutite with variable amounts of spar and fossil allochemical grains. Associated flanking facies consist of mixed biosparite near the core, grading outward into oosparite. A few zones of shaly, poorly washed biomicrite containing rounded clasts bearing Archimedes fragments are interbedded with the flanking mixed biosparite facies. These clasts appear to …

Composition Of Arkansas Grapes During Maturation, Cameron Jones, Dominic T.C. Yang, Thomas O. Whitley

Journal of the Arkansas Academy of Science

Changes in organic acid and glucose content during maturation and ripening of grapes grown in Arkansas in 1973 are shown for four French hybrid varieties, S5279, S10878, SV23- 657, and S13053, and for four rotundifolia varieties, Scuppernong, Tarheel, Fry, and Magoon. In all varieties the concentrations of malates and tartrates were highest in the early stages of berry growth after veraison. During ripening the titratable acidity decreased and Balling and pH measurements increased. Although varieties reached maturity on different dates, changes in parameters followed similar curves typical for grapes of the species but occurring over a short period (Johnson and …

Water Quality In The Small Coastal Basins, Bruce J. Neilson

Reports

The Small Coastal Basins portion of the Hampton Raods 208 study area includes the Back and Poquoson Rivers on the Virginia Peninsula and Little Creek Harbor and the Lynnhaven Bay system on the southern shore of Chesapeake Bay, as shown in Figure 1. The drainage areas are characteristically small, ranging from only 63 square kilometers for Little Creek Harbor to 156 sq. km,for the Lynnhaven Bay system. All four basins lie entirely within the geological Coastal Plain Province, the low lying area between the Fall Line and the Atlantic Ocean. The soft sediments typical of this province erode easily, so …

Polymerization Of Amino Acids On Kaolinite, Z. Badri Adnani-Gleason

Dissertations and Theses

In the origin of life on the primitive earth a major step must have involved the condensation of amino acids to form the first polypeptides. Several suggestions as to how this might have occurred have been made by other workers. One of the more appealing proposals is that the polymerization was catalyzed by clay minerals. It has been reported, for example, that L-apartic acid polymerizes significantly faster than D-aspartic in the presence of kaolinite in aqueous suspension at 90˚. In this work an attempt was made to repeat this report and extend the pH range to include values presumably present …

Geology Of The Breitenbush Hot Springs Area, Cascade Range, Oregon, Clifford Michael Clayton

Dissertations and Theses

The Breitenbush Hot Springs area lies on the boundary of folded middle to late Tertiary Western Cascade rocks and younger High Cascade rocks. Within the mapped area the Western Cascade rocks are represented by four formations. The Detroit Beds, a sequence of interstratified tuffaceous sandstone, mudflow breccia, and tuff, is overlain unconformably by the Breitenbush Tuff. The Breitenbush Tuff consists of three units of welded pumice-rich crystal-vitric ash-flow tuffs interbedded with tuffaceous sedimentary rocks. The Outerson Formation unconformably overlies the Breitenbush Tuff and consists primarily of basaltic lava and breccia.

The Outerson Formation includes three localized members: a basal, glassy, …
