Petrology of Kahoolawe Island, Hawaii: Tholeiitic, Alkalic, and REE, Y-Enriched Basalts and Xenoliths as Insight to Hawaiian Magmatism and Petrogenesis

这个项目代表了对从夏威夷卡霍奥拉维岛收集的200多个玄武岩样本的全面岩石学研究。对地球化学异常样本以及代表Kahoolawe完整地层学和结构的样本的检查将为夏威夷岩石学和稀土元素运输提供新的视角，因为在夏威夷火山地层学的背景下还没有对这些特征进行过检查。对这些玄武岩进行主量元素和微量元素分析，包括稀土元素。将测定相组成并得到K-Ar年龄。该计划旨在描述该岛的特征，解释和确定其各种岩石学特征的起源，并利用异常特征来模拟夏威夷岩浆作用和火成岩作用的新方面。然后，这些数据将用于修改和更充分地发展现有的玄武岩岩浆作用的岩石成因模型。

This project represents a comprehensive petrologic study of more than two hundred samples of basaltic rock collected from Kahoolawe Island, Hawaii. Examination of geochemically anomalous samples along with those representing the full stratigraphy and structure of Kahoolawe will provide a new perspective on Hawaiian petrology and rare-earth element transport , in than no such features have yet been examined within the context of Hawaiian volcanic stratigraphy. These basalts will be analyzed for major- and trace-elements including REE. Phase compositions will be determined and K-Ar ages obtained. The plan is to characterize the island, interpret and establish the origins of its varied petrologic features, and use the anomalous characteristics to model new aspects of Hawaiian magmatism and igneous processes. These data will then be used to modify and more fully develop existing petrogenetic models for basaltic magmatism.
