South Central Andes Gravity,New Data Base

From 1993 to 1998 approximately 3.927 gravity stations were taken in the Central Southen Andes, comprising the<br>southern central zone of Chile and the central western part of Argentina, between latitudes 37.50ºS to 42.5ºS and<br>69ºW as far as the coast of the Pacific Ocean. To this information, 9.123 old stations were included, which were<br>reprocessed and when in some doubt, were remeasured. Now the the database contains 13.050 gravity stations<br>available which can be used along with other geophysical and geological information for an interdisciplinary<br>interpretation to be able to understand some structural aspects and evolution of the Southern Central Andes. In<br>this paper, we present the new data base by means of maps of Bouguer anomaly and isistatic anomaly, together<br>with a very preliminary interpretation.
