Cenozoic Volcanism and Crustal Evolution in Northern Mexico:Integrated Studies of Volcanic Rocks and Xenoliths

该项目旨在研究晚新生代卡玛戈玄武岩油田新发现的捕虏体位置，并继续对中新生代火山岩进行研究。一些新遗址有地壳捕虏体套件，其中包含镁铁角闪质麻粒岩和镁铁质火成岩堆积体，它们可能代表不同级别的地壳。其目的是建立陆相火山岩演化的最佳约束模型。该模型将以火山岩、同时代堆积岩、围岩和地幔包体为基础。这个项目将测试目前的数学模型在重现各种岩石类型的同位素、主元素和微量元素化学方面的成功程度。

This project is to study new xenolith localities recently found in the late Cenozoic Camargo basalt field, and to continue research on mid-Cenozoic volcanic rocks. Some of the new sites have crustal xenolith suites containing mafic hornblende granulites and mafic igneous cumulates, that may represent different levels of the crust. The objective is to construct the best constrained model possible for the evolution of continental volcanic rocks. This model will be based on the volcanic rocks, contemporaneous cumulates, wall rocks, and mantle xenoliths. This project will test how successful current mathematical models are in reproducing the isotopic, major-element, and trace-element chemistries of the various rock types.
