Geophysical imaging of subsurface properties and magnetostratigraphy of sedimentary records (D07*)

该分项目侧重于地球物理方法的应用和发展，以支持解释智利和纳米比亚的新型档案和未勘探遗址。我们的目标是（1）应用多尺度的地球物理成像技术，并开发一种灵活的利用地震约束的瞬变电磁反演算法，（2）改进利用磁性地层学对沉积记录的年龄控制;为阿塔卡马沙漠开发了第一个RPI主记录，以及矿物磁性代用指标的识别，以揭示气候演变的细节。

The subproject focusses on the application and development of geophysical methods, to support the interpretation of new kind of archives and unexplored sites in Chile and Namibia. Our objectives are (1) the application of geophysical imaging techniques at multiple scales, and the development of a flexible inversion algorithm for Transient Electromagnetics using seismic constraints, and (2) the improvement of the age control of sedimentary records using magnetostratigraphy; the development of the first master record of RPI for the Atacama Desert, and the identification of mineral magnetic proxies to unveil details of climatic evolution.
