Abstract
Sixty-two samples from well-established comagmatic granitoid sequences and certain unassigned formations and plutons of the central part of the Sierra Nevada Batholith have been dated by the isotopic U-Pb method on zircon. The distribution of ages is consistent with the interpretation that, in this area, a belt of Cretaceous granitoids trending about N. 20 degrees W. crosses a belt of Jurassic granitoids trending about N. 40 degrees W.--from New Publications of the Geological Survey, Jan. 1982.
