The hydrology and mineralogy of Deep Springs Lake, Inyo County, California

Abstract

Page A25 27 32 40 42 43 43 44 45 48 48 49 49 53Springs Lake with experimental data on burkeite stability (Jones, 1962) with results of work by Teeple (1929) on the quinary Na2COs-NaHCOs-Na2S04-NaOl-H20 suggests that the salines reflect their original sequence of precipitation but trend toward local equilibrium with associated brines. ACKNOWLEDGMENTS For much assistance in this study, I am especially grateful to Prof. Hans P. Eugster of the Johns Hopkins University, who participated in selection of the area for detailed study and provided detailed advice and constructive criticism of the manuscript. I am indebted to Prof. Charles B. Hunt also of the Johns Hopkins University for critical reading of the manuscript, and to Betty F. Jones for the manuscript outline and preliminary organization.

The Origin of the Mediterranean Evaporite

“…In an excellent review, Schmalz (1970) pointed out that such a model would result in a tear-drop lateral distribution pattern ( Figure 5), rather than the bullYeye pattern typical for the salina type of evaporite deposit (Figure 2). The latter is well known (Hunt et al, 1966;Jones, 1965;Hardie, 1968). A gradual desiccation of a playa would result in concentric zones of evaporite distribution-the outermost carbonate being the first salt to precipitate from a brine, and the inner core the most soluble salt.…”

“…The groundwater is fed by many springs surrounding the playa, some of which are artesian. Seasonal lake formation occurs within the wet period of the year, drying in summer to form salt crusts with horizontal zonation from playa margins to the centre: calcite/aragonitedolomite-gaylussite-thenardite-burkeite; and vertical zonation from lower to upper layers: carbonate muds-nahcolite-thenardite-burkeite-trona-halite + sylvite [77,78].…”

“…La actividad del ion Na+ está relacionada con la salinidad del medio. De acuerdo con Jones (1965) y Eugster (1970, se consiguen altas actividades de este ion en las salmueras intersticiales que se encuentran al borde del lago salino, es precisamente en esta zona donde comienza a aparecer analcima.…”
