The Complejo Metamorfico of Chilenia: Implications for the Paleozoic Tectonics of Western Argentina and Chile

人们早就认识到，新生代安第斯山脉所在的地壳具有复杂的构造热史，可以追溯到前寒武纪。由于缺乏充分的、最新的构造-岩石学数据库，最近的区域理论对智利地区的适用性测试受到了阻碍。这一现场项目是一项开创性的工作，将在这一重要领域收集关键的新结构、时间和岩石学数据。这些结果将对南美洲的地质发展和冈瓦瓦兰的重建产生重要影响。

It has been long recognized that the crust upon which the Cenozoic Andes Mountains are founded have had a complex tectonothermal history that dates back to the Precambrian. Testing of the applicability of recent regional theories to the Chilenia area have been hampered because of the lack of a sufficient, up-to-date, structural-petrologic database. This field project is a pioneering effort that will gather critical new structural, timing, and petrologic data in this important area. Results will have important implications for the geologic development of South America and for the reconstruction of Gondwanaland.
