Abstract: Subterranean sandy and silty sedimentary formations are examined to determine that mineral crystals, known to grow most favorably in alkaline, saline conditions that typify a marine depositional environment, are authigenic, i.e. formed in place, in the sedimentary formation. This indication of the nature of the depositional environment is useful for further exploration by geologists in seeking the presence of petroleum deposits.
