The Casale Basin: sedimentation synchronous with Oligocene magmatic activity (30–26 Ma) at the southern end of the Maricunga Belt
Quiroga, R., Mpodozis, C., Clavero, J., Droguett, B.
Abstract
Describes the Río Nevado Strata, which record an Oligocene volcanic system and sedimentary basin (the Casale Basin) in the Nevado de Jotabeche area, host rock of the Casale deposit.
The Casale Basin is a half-graben bounded by a NE-trending fault, with red conglomerates and sandstones overlain by playa-lake evaporitic deposits. To the north, block-and-ash breccias associated with rhyodacitic domes, tuffs and dacitic lavas dominate, representing a volcanic event of 30 to 26 Ma.
Study funded by Sernageomin for the Geological Map of the Nevados de Jotabeche area.
