Controls of Tufa Development in Pleistocene Lake Bonneville, Utah
Prominent tufa localities along the Provo level (∼14,000 C yr B.P.) shoreline in Pleistocene Lake Bonneville have been characterized in detail. Three types of tufa are recognized: capping tufa, beachrock, and capping tufa over beachrock. Capping tufa and beachrock are end members of a continuum based on variable clastic content. All three types typically occur on headland environments that had ...
