应地球科学学院王伟教授和李睿博士邀请，爱尔兰都柏林圣三一大学David Chew教授来我校访问并作学术报告。

简介

汇报人：Professor David Chew

汇报内容：LA-ICP-MS imaging in the geosciences and its applications to geochronology

汇报简介：LA-ICP-MS mapping is a rapidly expanding field in the geosciencesbecause of the wealth of spatial information it provides on the petrogenesis of igneous, metamorphic and sedimentary rocks and ore mineral formation.This growth in applications is linked to instrumentation advances including the development of low dispersion (fast-washout) LA cells. U-Pb analysis of materials with variable initial Pb concentration sand/or heterogeneous genetic origin such as carbonates also benefit from such a mapping approach as areas with sufficient spread in ²³⁸U/²⁰⁴Pb ratio (M) can be targeted, while simultaneous imaging of diagnostic trace elements allows identification and exclusion of zones affected by alteration or detrital contamination.
