Comparison of radioactivity and geochemistry of rocks from plutonic bodies adjacent to the southern part of Golfo of California
Main Article Content
Abstract
The comparison of modal composition and contents of major, radioactive (U, Th, K) and selected (Rb, Sr, Ba, Y, Zr, V, Cr, Ni) trace elements of granitic rocks from the Jalisco and Baja California Sur plutonic complexes supports the idea that they were part of a single batholithic body separated later by the process of opening of the Gulf of California.
