... We describe the depositional environments of the Cache, Lower Lake, and Kelseyville Formations in light of habitat preferences of recovered mollusks, ostracodes, and diatoms. Our reconstruction of paleoenvironments for these late Cenozoic deposits provides a framework for an understanding...

... are dominated by planktonic genera such as Stephanodiscus , Cyclotella , and Melosira . Shallow-water species of Fragilaria and Amphora are common and sometimes abundant. Several planktonic diatoms from the core are also found in the Kelseyville Formation, which is exposed on the southern margin of Clear...

... basins in northern California. Comparison of cores from Clear Lake with strata of the Kelseyville Formation, exposed south of the main basin, suggests a general northward migration of lacustrine sedimentation, which in turn suggests a northward tilt of the basin. Migration of the lake was a response...

... to the trend of the fault ( DeMets et al., 1990 ) (Fig. 1A) . Rather than transpression-driven or subduction-related uplift, the underlying cause for the formation of the Coast Ranges is more likely processes associated with the passage of the Mendocino triple junction ( Zandt and Furlong, 1982 ; Furlong...

..., 1967 , 1999 ). Ore deposition in high-sulfidation deposits is associated with advanced argillic alteration and intense acid leaching ( Heald et al., 1987 ). The formation of vapor-dominated chimneys that serve as conduits for the upward migration of magmatic SO 2 -rich gas is important in controlling...

... to connate or formation waters (derived from ancient seawater) that discharge from Franciscan and Great Valley sediments and are found throughout the Clear Lake volcanic field ( White et al., 1973 ). Donnelly-Nolan et al. (1993) noted that the isotopically heavy end member discussed in The Geysers...
