...). The point at the location of Lake Surprise (California) corresponds to the average precipitation anomaly (22 ± 195 mm/yr) calculated from Equation 10 (587 ± 103 mm/yr) and modern precipitation rates (566 ± 165 mm/yr) for all LGM-age tufa. LGM-age tufa are defined as those dated between 19 and 23 ka...

...Elin Tollefsen; Gabrielle Stockmann; Alasdair Skelton; Carl-Magnus Mörth; Christophe Dupraz; Erik Sturkell ABSTRACT The hydrated carbonate mineral ikaite (CaCO 3 ·6H 2 O) is thermodynamically unstable at all known conditions on Earth. Regardless, ikaite has been found in marine sediments, as tufa...

... to the same insolation forcing. We have also dated tufa from a shoreline remnant above the Holocene highstand of Ngangla Ring Tso using U-Th. The resulting age of 211.2 cal ka indicates that remnant shorelines are much older than the Holocene features in Tibetan systems. Our ages are supported...

The engineering behaviour of tufa is dependent on the depositional environment, diagenesis and weathering characteristics. An engineering classification of tufa should include primary fabric, post-depositional...

..., or left open. However, detailed macroscopic, microscopic, and geochemical analyses of these features reveal that they are, instead, macrophyte (stem) encrustations that form in standing water. While these features form in a manner similar to paludal tufa, they do not resemble typical tufa deposits (e.g...

A critical geological re-interpretation of this area indicates that the Quaternary succession, composed by a relatively thin veneer of terrigenous deposits and by calcareous tufas , is the result of five major stages of drainage reorganization. The data from this study indicate that, similarly...

.... Sedimentation is mainly biogenic with the laying down of thick charophyte-rich tufas interbedded with silty layers in distal areas and palaeosols in proximal areas. These alternations point to four major deposit sequences with lowstand phases. The first two phases are dated at ca. 2426 and 1869 cal B.P...
