Horizontal displacement of surveyed points during 1932-1959 have been analyzed to determine strains. The east-west trending, north-dipping Buena Vista Hills thrust fault divides the area. The direction of greatest contraction...

Folds that have widely dispersed trends in outcrop of the northern Ruby Mountains, Nevada, show a common sense of overturning that is interpreted to be the flow line of velocity-gradient...

Graben with superimposed compressional and normal fault structures, Mesozoic deformation, spatial relationships indicative of right lateral movements of marginal cratonic blocks, effects of Precambrian lineaments

An unequivocally Hemphillian fauna of the Bone Valley type is described from the Manatee County dam site. Three habitats (savannah, stream, and estuary) are present. Sharks are the most abundant;...

Two types of rock glaciers of Wisconsin age occur on the northern slopes of the highest peaks. Tongue-shaped rock glaciers, 300-800 feet long, occur in cirques. Lobate rock glaciers occur...

Magmatic heat that is available for transfer to wall rock is derived from the heat in the silica fraction, the heat in the volatile fraction, and the heat of the...

Experiments in iron-rich interstitial water taken from sediment of Linsley Pond, Connecticut have shown that a potential-determining reaction exists for platinum electrodes which do not carry a deposit of ferric...

Noble shows where the presence of calcium has a larger effect on the system than was suspected by Lipman, (ibid., v. 264, no. 10, p. 810-826, 1966) and therefore the...
