clay (percent)

variableName: clay

description: "Here, we propose a depositional model stating that high percent clay values (or intervals of clay dominance) indicate persistent standing water wherein the deposition, accumulation, and preservation of fine- grained sediment exceeds an undefined critical thickness that inhibits deflation during succeeding desiccation events or ephemeral lake environments."

C/N (unitless)

TSid: WEB696efa25

variableName: C/N

units: unitless

description: " In Silver Lake, changes in these ratios (C/N) are interpreted to reflect changes in the source of organic matter under relative perennial vs. ephemeral lake states. Perennial lakes pro- mote lake productivity producing low Corg:Ntotal ratios. Ephemeral lakes are associated with higher Corg:Ntotal ratios as the contribution of terrestrial organic matter increases in the presence of lower lake levels and the subsequent encroachment of terrestrial organics onto the playa surface.
