9627839 McDowell This grant provides $17,000 as partial support of the costs of acquiring components to upgrade the Potassium-Argon geochronology laboratory in the Department of Geological Sciences at the University of Texas. Specifically, turbomolecular pumps will be purchased to replace antiquated and potentially hazardous mercury diffusion pumps used to maintain a vacuum within the sample preparation lines and the physical components of the sample preparation line will be rebuilt. This laboratory is presently 25 years old and these upgrades will allow this lab to maintain a safe and viable future program of research utilizing K/Ar geochronology as applied to studies of the magmatic history of northwestern Mexico and the tectonic and magmatic history of Irian Jaya in western New Guinea. ***

小行星9627839 这笔赠款提供了17 000美元，作为购买部件的部分费用，以更新得克萨斯大学地质科学系的钾氩地质年代学实验室。 具体而言，将购买分子泵，以取代用于保持样品制备线内真空的陈旧和具有潜在危险的汞扩散泵，并将重建样品制备线的物理部件。 该实验室目前已有25年的历史，这些升级将使该实验室能够利用K/Ar地质年代学保持一个安全可行的未来研究计划，用于研究墨西哥西北部的岩浆史和新几内亚西部伊里安查亚的构造和岩浆史。 ***
