Middle to Upper Crustal Magmatic Arc Construction in the Mojave Province and Tujunga Terrane of Southern California

主要研究人员记录了南加州图琼加地体边界上中生代弧形发展的起源。他们将利用野外、岩石学、化学、同位素和矿物学信息。一个重要的结果将是对大陆边缘岩浆弧的中地壳和上地壳部分的岩浆作用进行评估，这些大陆边缘岩浆弧覆盖或包含相当大比例的元古界基底。总的来说，这些信息将有助于地质学家了解地壳的地质发展。

The principal investigators document the origin of Mesozoic arc development across the Tujunga terrane boundary in southern California. They will utilize field, petrologic, chemical, isotopic, and mineralogic information. An important result will be an evaluation of the magmatic processes operative in the middle and upper crustal portions of continental margin magmatic arcs that overlie or contain a sizeable proportion of Proterozoic basement. In general this information will help geologists under-stand the geologic development of the Earth's crust.
