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.

这项研究将得到莫斯科Vernadsky地球化学研究所的G. V. Nesterenko博士的田野，地质和科学建议的支持，莫斯科已经提供了大约50个西伯利亚洪水盆地省（SFBP）的样本，这些省份是新鲜的，并且在其火山界面的角度良好。 这项最初研究的计划是通过分析SM-ND，RB-SR和U-TH-PB系统的其余样品来表征SFBP中的总时间和空间变化。 这些样品中的一些也被选中进行谷物挑剔，以在人类起源研究所进行激光加热的40AR/39AR年龄确定。 拟议的有关SFBP的研究将提供新的信息，通过这些信息来研究和解释其他洪水玄武岩省的起源。
