Title: Recognition of Playa Sediments in the Geologic Column.: ABSTRACT

Author(s): Richard Stone

Article Type: Meeting abstract


Playa sediments are sometimes reported in oil-well cuttings, particularly in sediments whose age

is Miocene or younger. A careful investigation of the sedimentary properties of playa sediments of the present has revealed certain characteristics which it is believed will enable the geologist to definitely recognize older sediments which were deposited in the playa environment. These diagnostic properties include the average grain size, sorting coefficient, color, organic carbon content, alkali and salt content, hydrogen-ion concentration, and the oxidation-reduction potential. In playa sediments most of these properties have rather definite ranges. This makes it possible to recognize playa sediments with a greater degree of certainty.
