U.S.-Brazil Cooperative Research: Sao Francisco Craton Margin Transect Project, Minas Gerais Brazil

该奖项支持由伊利诺伊大学厄巴纳分校的Stephen Marshak博士、Lamont-Doherty地质观测站的Hannes Brueckner博士以及Fernando Alkmim、Hanna Jordan t Evangelista和Farid Chemale Jr.博士开展的地质学合作研究。来自巴西联邦大学(UFOP)。该项目的目标是确定圣弗朗西斯科克拉通东缘的详细构造历史。这一边缘的一个或两个详细横断面将包括新的构造地质学和岩石学实地研究，新的高级地质年代学分析，以及该地区现有但基本上不可用的当地研究的综合。该项目的结果将确定沿海活动带以西的布拉西利亚诺构造作用的几何学、样式和时代；沉积晚元古代地层的盆地的性质；以及前巴西利亚诺造山作用的时代和样式。该奖项将促进美国和巴西之间富有成效的合作的继续。

This award supports cooperative research in geology to be conducted by Dr. Stephen Marshak of the University of Illinois, Urbana, Dr. Hannes Brueckner of the Lamont-Doherty Geological Observatory and Drs. Fernando Alkmim, Hanna Jordt Evangelista and Farid Chemale, Jr. from the Universidade Federal de Ouro Preto (UFOP), Brazil. The objective of the project is to work out the detailed tectonic history of the eastern margin of the Sao Francisco craton. One, and possibly two, detailed transects of this margin will incorporate new field studies of structural geology and petrology, new advanced geochronological analysis, and a synthesis of existing, but largely unavailable, local studies in the region. The results of the project will define the geometry, style and age of the Brasiliano tectonism west of the coastal mobile belt; the nature of the basins in which Late Proterozoic strata were deposited; and the age and style of pre-Brasiliano orogenies. The award will foster continuation of a productive U.S.-Brazil collaboration.
