Geology of the Tierras Blancas Area in the Southeastern Acambay Graben, Central Mexico
… The sediments deposited in this late Pliocene paleolake record a history of lake level fluctuations, shown by lithologic variations in lacustrine sediments and abundance of vertebrate burrows. Volcanic and tectonic events in the Acambay graben were the major controls on sedimentation during …

Spatiotemporal Slip Rate Variations Along Surprise Valley Fault in Relation to Pleistocene Pluvial Lakes
… allowing for correlations with changes in paleolake levels. This study suggest iv complex relation between pluvial lakes and their proximal faults that show that the lake likely influenced earthquake recurrence and slip rate along the SVF.

A Reconstruction of Precipitation and Hydrologic Variability on the Peruvian and Bolivian Altiplano During the Late Quaternary
… deep, consistent with paleoshoreline evidence of paleolake Minchin (46-36 ka). From 36-26 ka a shallow lake <10 m deep occupied the Coipasa basin. During the LGM (26-21 ka) the lake varied from moderate to shallow and during the Holocene (< 10 ka) the lake evolved from a shallow lake to a salt …

Investigating laminated sediments of the Al-Azraq basin, Jordan and the implications for paleoenvironmental variability
… for laminated sediments and characterize the paleolake environments. Lithology and smear slides identified the presence of fine laminated sediments and diatoms. Detailed examination of ten sediment sections totaling 5.76 meters identified three sediment sections 2.02 m in length for further …

Reconstruction of aspects of Northern New Zealand paleoclimate over the last 200 ka using laminated Auckland maar lake sequences
… reconstructions. In this context Onepoto maar paleolake in the Auckland Volcanic Field is important as it contains a high-resolution record of continuous sedimentation in the lake from its formative phreatomagmatic eruption ≤190 ka until the post-glacial sea-level rise breached the crater tuff …

Seismic reflection imaging of near surface structures using the Common Reflection Surface (CRS) Stack Method
… delineating the hydrogeological framework of a paleolake environment to a depth of few hundred metres. Using the CMP method, several nearly horizontal reectors with onsets from 60 to about 250 ms were imaged. The CRS stack produced a stacked section with greater coherency and lateral continuity …
