Collaborative Research: Multichannel Seismic Investigation of Lake Baikal: Structure and Stratigraphy of the Upper Crust

这是一个由美国地质调查局和来自海洋研究所、湖泊研究所、地质和地球物理研究所以及地壳研究所的俄罗斯科学家参与的合作项目。该计划旨在开发贝加尔裂谷系统的详细结构和地层学历史。该计划的内容包括处理和解释俄罗斯同事已经收集的多道地震数据，从贝加尔湖收集新的、更高分辨率和更准确导航的MCS数据，处理和解释这些新数据，以及将所有可用的数据集整合到大陆裂谷发展的综合模型中。该方案的目标包括：o重建贝加尔湖下方那部分贝加尔裂谷的构造和地层演化；O开发湖盆演化模型；以及将解决构造事件的定时和沉积模式变化的问题的适当钻探地点的位置，这将为气候变化和生物进化的研究提供最连续的部分。

This is a cooperative program involving the U.S. Geological Survey and Russian scientists from the Institute of Oceanology, Institute of Limnology, Institute of Geology and Geophysics, and Institute of the Earth's Crust. The program is aimed at developing a detailed structural and stratigraphic history of the Baikal Rift system. Elements of the program include the processing and interpretation of multichannel seismic data already collected by Russian colleagues, the collection of new, higher resolution and more accurately navigated MCS data from Lake Baikal, the processing and interpretation of these new data, and the integration of all available data sets into a comprehensive model of continental rift development. Objectives of the program include: o Reconstruction of the structural and stratigraphic evolution of that portion of the Baikal Rift that underlies Lake Baikal; o Development of models for the evolution of the lake basins; and o Location of appropriate drilling sites that would address the problems of timing of structural events and shifts in patterns of deposition, and that would provide the most continuous sections for studies of climate change and biologic evolution.
