Abstract

The study area extends to the north and western of Sierras Australes. It has been surveyed 700 stations for gravimetry and magnetometry and the calculated anomalies were positioned in the Tornquist, Pigüé, Guaminí and Coronel Suárez map sheets. The survey was done at 1: 200,000 scale. Gravimetric sections were made in W-E and SW-NE directions in order to get an estimation of the sediment thickness. Based on these date the extension of the Paleozoic was determined. The thickness reaches up to 6,000 m and 5,200 square kilometers. The Claromecó basin extends to the NW in the western side by 145 km with a width of 48 km. The observed magnetic anomalies of the total field magnetic map are small pointing out the presence of moderate magnetic minerals. The existence of refraction seismic lines provided by Y.P.F. and DYMAS for the neighboring areas of Carhué allows a precise thickness of the Tertiary sediments.
