- Quantitative mineralogical analyses for major minerals and qualitative analyses for trace minerals were made on 28 samples, all of which were analyzed chemically. Quartz grain-size distributions were measured on 28 samples. Physical tests made on several samples were hardness, density, point-load strength, directional-tensile strength, air permeability, directional-sonic velocity, and pore-size distribution. It was found that the clay mineral, kaolinite, was a major mineral in Well Core No. 20336, but no traces of kaolinite were formed in the Devonian shales of New York State. Both the point-load and directional-tensile strengths showed that the Devonian shales, in general, were stronger in the NW-SE direction than in the NE-SW direction. It was also observed that the shales were stronger with increasing quartz or silicon contents and weaker with increasing amounts of micaceous, disilicate minerals. As expected from previous work, the quartz grain-size distributions were skewed toward the larger sizes when the frequency curves were plotted linearly. An exhaustive analysis of all the data obtained was not attempted, since it was not a part of the contract.
