Canto del Agua Formation (Chile) | |
Canto del Agua Formation (Spanish: Formación Canto del Agua) is a geological formation in the Atacama Region of northern Chile. Its stratigraphy from top to bottom is as follows: mudstone, limestone, sandstone, mudstone, conglomerate, lapilli tuff, conglomeratic sandstone, muddy sandstone.[1] The environment where the sediments of the formation deposited is thought to have been the "submarine section of a coarse-grained fan delta" with other authors adding that the sedimentary basin where the sediments deposited was "bounded by two normal faults of WNW strike, active during deposition".[1] The exact relationship with the underlying Llano de Chocolate Beds is not clear.[1] In some locations the formation overlaps directly on the Punta de Choros Metamorphic Complex.[1]
The type locality of the formation lies next to the Plomiza mine.[1]
