Revisiting silicate authigenesis in the PliocenePleistocene Lake Tecopa beds, southeastern California: Depositional and hydrological controls

Daniel Larsen, Dept. of Earth Sciences, University of Memphis, Memphis, Tennessee 38152, USA.

The Pliocene-Pleistocene Lake Tecopa beds have long been identified as a type-example of the concentric distribution of low-temperature sedimentary minerals, such as zeolites and feldspars, that are believed to have formed in and help identify ancient saline, alkaline lake deposits. In the present study, the sedimentary and hydrologic process controls on the formation of these low-temperature mineral zones are investigated through detailed mineral and sedimentology studies, as well as conceptual hydrologic modeling. The results indicate that ancient lake-level or, more specifically, lake-surface area and sediment composition are the most important controls on the type of sedimentary mineral formed along the lake basin margin. However, sediment grain-size and vertical migration of salty brines control the sedimentary mineral formation in the center of the basin. These results provide some guidance as well as caution to interpretation of paleohydrology and paleoclimate of ancient lake beds based on cores from the center of saline, alkaline lake basins.
