Upper Mantle Project: Andean Geophysical Program

Largely as a result of an informal meeting (in the fall of 1965) of geophysicists from the Andean region, a formal meeting of a Study Group for a Program of Upper Mantle Studies in the Central Andes was held in Lima, Peru, September 12–14, 1966, to review the most recent results and to evolve plans for a program of regional geophysical studies of the Andean Cordilleran System as part of the Upper Mantle Project. (A very general preliminary statement was published in UMP Report 3, pp. 231–237.) The meeting was convened by the Centro Regional de Sismología para América del Sur with financial assistance from Unesco, with the endorsement of the International Upper Mantle Committee and the Pan American Institute of Geography and History, and with the endorsement and support of the Carnegie Institution of Washington and, locally, of the Institute Geofisico del Perú. The Study Group included geophysicists from Andean countries: Fernando Volponi (San Juan, Argentina); Luís M. Fernández (La Paz, Bolivia); Enrique Gajardo, Edgar Kau'sel (Santiago); Rudolf Schulz (Valdiva, Chile); Antonie Scheepmaker (Quito, Ecuador); Ramón Cabré, Ing. Mateo Casaverde, Germán Saá, Enrique Silgado (Lima, Peru); Daniel Ochoa and Anibal Rodriguez (Arequipa, Peru). Others attending were: representatives of the Pan American Institute of Geography and History (Manuel Maldonado‐Koerdell), International Upper Mantel Committee (Pembroke J. Hart), and Carnegie Institution of Washington (L. T. Aidrich); and observers from the University of the West Indies, Trinidad (John Tomblin) and U. S. Regional Science Office, Rio de Janeiro (Francis Morthland, Richard E. Krause, and Oscar Berthold).
