Lacustrine turbidites as indicators of Holocene storminess and climate: Lake Tahoe, California and Nevada

Reconstructing 2000years of hydrological variation derived from laminated proglacial sediments of Lago del Desierto at the eastern margin of the South Patagonian Ice Field, Argentina

“…This block is interpreted as a lake internal slump layer (cf. Osleger et al, 2008). Throughout units A and B the mean clay content reaches 18% while the sand fraction rises up to 30% at defined layers (10% in mean; Fig.…”

“…3. Gilbert, 1994;Osleger et al, 2008). In contrast to the uppermost sections unit C seems to represent almost undisturbed sedimentation.…”

Peat Formation Processes Through the Millennia in Tidal Marshes of the Sacramento–San Joaquin Delta, California, USA

“…Currently, sediment delivery to the watershed is largely related to storm activity (Wright and Schoellhamer 2005). This relationship appears to be longstanding as research on Lake Tahoe, California sediments suggests that storms have been a major agent for the mobilization of sediments in the region for the past 7,000 years (Osleger et al 2009). …”

Turbidite systems of lacustrine rift basins: Examples from the Lake Kivu and Lake Albert rifts, East Africa

“…Hyperpycnal flows are more frequent in lacustrine basins than in marine environments (Mulder et al, 2003). Frequent hyperpycnal river flows have been documented in modern rift lakes, e.g., Lake Tanganyika (Tiercelin et al, 1992) and Lake Tahoe (Osleger et al, 2009). Previous investigations have suggested that the ability of rivers to produce hyperpycnal flows increases with high relief and steep slopes (Mulder et al, 2003), which are characteristic of rift lake basins.…”

“…Turbidite systems comprise a large fraction of the sediment volume of many lacustrine rift basins (e.g., Soreghan et al, 1999), and have been observed in modern deep-water rift valleys, e.g., Lake Malawi (Scholz et al, 1990;Soreghan et al, 1999;Wells et al, 1999), Lake Baikal (Nelson et al, 1999), and Lake Tahoe (Osleger et al, 2009), as well as in ancient lacustrine rift systems such as the Cretaceous Recôncavo Basin (Bruhn, 1999) and the Cenozoic Songliao Basin (Feng et al, 2010). Previous investigations are converging to provide a clearer picture of the depositional processes of rift lake turbidite systems.…”
