Mid cretaceous contact seen below seymour island and followed off shore by the magnetotelluric method along the ne coast of the Antarctic peninsula

Fournier, H.G. / Demicheli, J. / Gasco, J.C. / Febrer, J.M. / Del Valle, R. / Keller, M.A. / Pomposiello, M.C. / Borzotta, E.

AbstractMagnetotelluric soundings were made on two off-shore islands and on the Larsen ice shelf. Below Seymour Island a thick sedimentary accumulation (6.7 km) is found. The mid Cretaceous contact is seen at a depth of 4.7 km. The first intermediate conductive layer appears at 65 km with a thickness of 20 km and a 10 ohm m resistivity. Two hundred km farther to the SW, from Robertson Island to Cape Fairweather, an anticline of the basement is possible; the depth ranges from 0.9 km at the top, to 2.3 and 3.6 km at the edges. The mid Cretaceous contact is followed off shore. The intermediate conductive layer begins at about 30 km depth on an average.
