Abstract
The geologic setting of the intrusive rocks between lat 39 degrees 52'30"" and 40 degrees 07'30"" N that are 70 m.y. old to 44 m.y. is collectively described. Whole-rock chemistry and semiquantative spectrographic analyses for each of the major intrusives and associated dikes are presented, and chemical relations and trends within the individual stocks, between stocks, and between stocks and associated dikes are shown graphically. Chemical trends for the stocks, especially the more mafic Caribou and Audubon-Albion stocks, indicate a common origin. The Caribou is the more mafic stock; the Audubon-Albion has the greatest chemical variation of all the stocks.
