原始语种摘要: The Cerro Quema district, located on the Azuero Peninsula, Panama, is part of a large regional hydrothermal systemcontrolled by regional faults striking broadly E-W, developed within the Río Quema Formation. This formationis composed of volcanic, sedimentary and volcano-sedimentary rocks indicating a submarine depositionalenvironment, corresponding to the fore-arc basin of a Cretaceous–Paleogene volcanic arc. The structures observedin the area and their tectono-stratigraphic relationship with the surrounding formations suggest a compressiveand/or transpressive tectonic regime, at least during Late Cretaceous–Oligocene times. The igneous rocks ofthe Río Quema Formation plot within the calc-alkaline field with trace and rare earth element (REE) patterns ofvolcanic arc affinity. This...
