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.

这项研究将得到实地、地质和科学的支持。 G博士的建议维尔纳茨基研究所的V. Nesterenko 地球化学在莫斯科，谁已经提供了大约50 西伯利亚洪水玄武岩区（SFBP）的新鲜样品， 在火山地层学方面也得到了很好的控制 岗位 这项初步研究的计划是表征 通过分析SFBP的总体时间和空间变化 其余样品进行Sm-Nd、Rb-Sr和U-Th-Pb系统分析。 其中一些样品也被挑选出来进行粮食采摘， 激光加热40 Ar/39 Ar年龄测定，将在 人类起源研究所。 关于SFBP的拟议研究 将提供新的信息， 其他泛滥玄武岩区的起源。
