Book Description

Excerpt from Fire-Flood Sequences on the San Dimas Experimental Forest The underlying rocks of the three watersheds are primarily meta morphic, consisting of several types of gneiss and some schist. Many dikes of hard igneous material such as pegmatite, dacite, and aplite have been injected through the metamorphic rocks. A large mass of granodiorite occurs in the southwest portion of watershed I. Smaller masses of quartz diorite occur in watersheds II and III. In general, both the metamorphic and granitic rocks are deeply fractured and weathered. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
