Abstract
This paper, based on observations in 1917, outlines the geographic and geologic range of petroleum indications in Argentina and the Atlantic watershed of Bolivia, and discusses the probable mother-rocks. Besides the Comodoro Rivadavia field on the Atlantic coast of Patagonia, where petroleum is produced in quantity, seepages and other evidences of oil are scattered along a sub-Andine belt over fifteen hundred miles long from southwestern Argentina to north central Bolivia, and range through many thousands of feet of the sedimentary series. The original sources appear to be sediments containing organic remains in formations of widely different ages, ranging from Devonian to Cretaceous. The chief source beds are here postulated as being the marine Devonian and Cretaceous in the northern Argentine-Bolivian belt; fresh or brackish water Upper Triassic near Mendoza; marine Upper Jurassic-Lower Cretaceous in southwestern Argentina; and marine Cretaceous or older beds on the Atlantic Coast.
