Water, Clay and Rock Soundness
Dunn, James R.; Hudec, Peter P. (1966-03)
The nature of water and clay in carbonate rocks is currently being investigated at Rensselaer Polytechnic Institute by various thermal and sorption techniques. Two basic concepts led to the present research. (1) To explain ...
Sedimentology of the Salem Limestone in Indiana
Smith, Ned M. (1966-03)
The Mississippian Salem Limestone, from which dimension stone is quarried in Indiana, is principally a calcarenitic rock formed of fossil bryozoans, echinoderms, and specimens of Endothyra. Numerical associations of the ...
Petrogrpahic Analysis of Northern Indiana Carbonate Aggregates
Aughenbaugh, N. B.; Lounsbury, R. W. (1966-03)
A study was made to determine those petrographic parameters that are correlative with carbonate-aggregate quality as indicated by the Los Angeles abrasion and absorption tests. Samples collected at 28 sites in northern and ...

Brewer, James E. (1966-03)
Procedure for approval by the U.S. Army Corps of Engineers of a new source of aggregate is in three phases. Phase 1 consists of an investigation of a quarry or proposed quarry by district geologist and laboratory geologist ...
Significance of Chert in Limestone and Dolomite Used as Concrete Aggregate
Kneller, William A. (1966-03)
Analysis of Plankton Ingested by Stizostedium Vitreum Vitreum (Mitchill) Fry and Concurrent Vertical Plankton Tows from Southwestern Lake Erie, May 1961 and May 1962
Hohn, Matthew H. (1966-03)
The analysis of plankton tows for May, 1961, and May, 1962, showed four species of diatoms, Melosira binderana, M. ambigua, Fragilaria capucina and F. crotonensis to be dominant. The analysis of the intestinal tract of the ...
Some Chemical Reactions in Silica Gels. I, Formation of Mercuric Iodide Crystals
Kurz, Philip F. (1966-03)
This investigation was concerned with reactions which form Hgl2 in acidic gels prepared with acetic acid and sodium silicate. The results of this work support the postulation that the yellow crystal frontal zone which ...
Observations on the Calls of the Grasshopper Mouse (Onychomys Leucogaster)
Ruffer, David G. (1966-03)
Calls of grasshopper mice include squeaks, chirping, a single high-pitched call, and a two-phase high-pitched call. The latter two are a means of intraspecific localization and are not a hunting call as previously supposed. ...
