Role of Mid-Crustal Plutonism in Extreme Crustal Extension, Southern Basin and Range

小行星9405175 岩浆侵入体通常与主要的大陆伸展有关，但它们之间的因果关系却知之甚少。 本研究将重点关注南部盆岭省的一个地区，该地区良好的暴露和大的地球物理异常的组合提供了限制伸展和深成岩作用之间关系的前景。 这项工作将获得几何数据或深成岩石和岩石将被几种技术定年。 将使用主要痕量和稀土元素化学研究深成岩的岩石成因。 结合广泛的区域数据，这些新的数据将允许大陆伸展，中地壳岩浆作用/岩浆作用和记录的地球物理异常之间的强有力的相关性。

9405175 John Magmatic intrusions are commonly associated with major continental extensions, however the causal relationship between them are poorly understood. This study will focus on an area in the southern Basin and Range province where a combinations of good exposure and large geophysical anomalies offer the prospect of placing constraints on the relationship between extension and plutonism. This work will obtain geometric data or the plutonic rocks and the rocks will be dated by several techniques. The petrogenesis of the plutonic rocks will be studied using major trace and REE chemistry. Combined with extensive regional data, these new data will allow a vigorous correlation between continental extension, middle crustal magmatisms/plutonism and the documented geophysical anomalies.
