Petrographic and Physical Properties Techniques for Study of Foundation Rock Morrow Point Damsite
During the foundation investigation of schists and gneisses at Morrow Point damsite, the rock (Nx cores) was petrographically described and classified for structural tests. Petrographic and physical tests of the core were grouped to give an overall picture of the foundation. Methods are described for determining the petrographic characteristics such as articulation, mineral composition, and microstructure of the rock. Articulation and texture of the grains were determined on the basis of microscope examination for evaluation of bond strength. Composition of the rock was determined by modal analysis (by a method of intercept distances) and the rocks were grouped according to minerals present. Oriented microstructures in foliated rocks were determined by the photometer method for analysis of structure. The relationship between elasticity and the texture, composition, and structure was compared. The relationship between absorption and seismic wave velocity was examined. Physical properties by means of laboratory and seismic methods were measured for individual rock types. (Author)
