Continuation of Support for a Technical Scientist in the Geochronology Laboratory, Washington University

这笔拨款为华盛顿大学圣路易斯分校地球与行星科学系（EPS）的VG Sector 54热电离质谱仪（TIMS）的维护和操作技术人员提供了两年的部分工资支持。这是第二阶段的技术支持补助金，并遵循三年的初始第一阶段支持（EAR-9506697）。作为第二阶段资助的条件，华盛顿大学已同意在该奖项到期后至少两年全额支付该技术职位的工资。这个地质年代学实验室继续在U/Pb、Sm/Nd和Rb/Sr放射性成因系统中进行高精度的同位素分析。目前马达加斯加火成岩和变质岩的年代学研究为新元古代板块构造和冈瓦纳大陆的形成和随后的分裂提供了有价值的约束

9816037TuckerThis grant provides two years partial salary support for a technician to maintain and operate the VG Sector 54 thermal ionization mass spectrometer (TIMS) in the Department of Earth and Planetary Science (EPS), Washington University - St. Louis. This is a phase II technician support grant and follows three years of initial Phase I support (EAR-9506697). As a condition of Phase II funding, Washington University has agreed to fully underwrite the salary for this technical position for a minimum of two years beyond the expiration of this award.This geochronology lab continues to produce high precision isotopic analyses within the U/Pb, Sm/Nd and Rb/Sr radiogenic systems. Current geochronologic studies of igneous and metamorphic rocks from Madagascar are providing valuable constraints on Neoproterozoic plate tectonics and the formation and subsequent breakup of Gondwanaland.***
