Lake Chalco

Lake Chalco (Mexico)

Department S5 participated in a drilling campaign at Lake Chalco in Mexico City in spring 2016 as part of the ICDP project MexiDrill. Detailed measurements of the physical properties were carried out in a core drilling approx. 410 m deep. The main objectives of the overall project are the investigation of the long-term climate development and the volcanological risk in this area of Central America (Brown et al. 2019). The borehole geophysical measurements in the former now silted up lake form an essential basis for answering many of the questions of the project consisting of an international team of all geoscientific disciplines. The interpretation of the borehole measurements allows, among other things, the preparation of a complete lithological log, the petrophysical characterisation of the drilled sediments, the determination of the position of sediment structures as well as statements on the paleoclimatic conditions up to about 400 ka ago.
