Collaborative Research: Petrogenesis, Age and Duration of the Siberian Flood Basalts

这项研究将得到莫斯科沃尔纳德斯基地球化学研究所G. V. Nesterenko博士的实地、地质和科学建议的支持，他已经提供了大约50个西伯利亚洪水玄武岩省（SFBP）的样本，这些样本是新鲜的，在火山地层位置方面得到了很好的控制。这项初步研究的计划是通过分析其余样品的Sm-Nd， Rb-Sr和U-Th-Pb系统来表征SFBP的整体时空变化。其中一些样品也被挑选出来，在人类起源研究所进行激光加热40Ar/39Ar年龄测定。对SFBP的研究将为研究和解释其他洪水玄武岩省的成因提供新的信息。

This research will be supported by field, geologic and scientific advice from Dr. G. V. Nesterenko of the Vernadsky Institute of Geochemistry in Moscow, who has already provided approximately 50 samples of Siberian Flood Basalt Province (SFBP) which are fresh, and well-controlled in terms of their volcano-stratigraphic positions. The plan of this initial study is to characterize the overall temporal and spatial variations in the SFBP by analyzing the rest of the samples for Sm-Nd, Rb-Sr, and U-Th-Pb systematics. Some of these samples are also selected for grain-picking to do a laser-heating 40Ar/39Ar age determinations, to be done at the Institute for Human Origins. The proposed research on the SFBP will provide new information through which to study and interpret the origin of other flood basalt provinces.
