Lacustrine carbonates in a 12.4-m-long core from Lower Pahranagat Lake (LPAH), southern Nevada, indicate that radiogenic isotopes of Sr and U (87Sr/86Sr and 234U/238U) preserve evidence of past variations in water sources and evolving hydrologic cond
On this field trip, we will examine a modern lake in central Nevada, the Lower Pahranagat Lake, and lacustrine carbonate outcrops of the late Miocene, upper Horse Spring Formation. Both of the modern and ancient systems hold significant microbialite

We present a continuous, sediment core-based record of paleohydroclimate spanning ~5800 cal yr BP to recent from Lower Pahranagat Lake (LPAH), a shallow, alkaline lake in southern Nevada. We apply stable isotopes (δ18O and δ13C) from fine-fraction

Thick Oligocene-Miocene lacustrine limestones of the Lake Mead region in southern Nevada have few adequate modern analogues that can shed light on their origin. We contend that the Lower Pahranagat Lake (LPAH), a spring-fed, alkaline lake in east-cen

Ecological shifts in shallow lakes from clear-water macrophyte-dominated to turbid-water phytoplankton-dominated are generally thought of as rapid short-term transitions. Diatom remains in sediment records from shallow lakes in the Prairie Pothole Re
