GEOLOGY ALONG THE NORTHWEST BORDER ZONE OF THE IDAHO BATHOLITH, NORTHERN IDAHO.

This report is based on petrologic and structural studies in western Clearwater County and in southern Shoshone County south of the St. Joe River, Idaho. Its purpose is to record the new data and reconsider the correlation, stratigraphy, and some petrologic aspects of the metamorphic rocks. Revision of correlation of the oldest metamorphic rocks is supported by fieldwork and by new information on their constituent minerals.
