        Writing with verve and clarity, Mary Hill tells the story of the magnificent Sierra Nevada--the longest, highest, and most spectacular mountain range in the contiguous United States. Hill takes us from the time before the land which would be California even existed, through the days of roaring volcanoes, violent earthquakes, and chilling ice sheets, to the more recent history of the Sierra. morillonite, or both, during weathering of plagioclase feldspar. A ratio of silica with respect to sodium, found in some samples, suggests formation of kao- linite by weathering of hornblende. These reactions involve only water and minerals known Cited by:

Kharaka, H.L. Barnes. Geology of Paleozoic rocks in eastern Sierra Nevada roof pendants, California. Rocks in the major roof pendants of the eastern Sierra Nevada have been mapped in various degrees of detail to bet- ter understand their stratigraphy, internal structure, and geologic history, and their relationships to other rock assem- blages in the region.

Abstract. The Shoo Fly Complex, the remnants of an early to middle Paleozoic subduction system, contains the Culbertson Lake allochthon. Included in the Culbertson Lake allochthon are the post-Cambrian and pre-Upper Devonian Quartz Hill, Toms Creek, and McMurray Lake cherts. Geochemical data derived from these three units plot on Cited by: the southern Sierra Nevada batholith is structurally more com-plex than the central and northern Sierra Nevada batholith.

As a result, the southern Sierra Nevada batholith deviates from the well-preserved, intact primary geochemical and petrologic spa-tial variations of the central and northern Sierra Nevada batholith.

There is no sharp geochemical discontinuity in the crust between the eastern and western segments of the Jiangnan orogen (JO).
