Tufa. Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine. Tufa is sometimes referred to as (meteogene) travertine. [1] It should not be confused with hot ...What Are Sedimentary Rocks? Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, conglomerate, sandstone, siltstone, and shale. Chemical sedimentary …

Clastic (detrital) sediments are broken fragments of preexisting rocks that have been transported and redeposited. Clastic sediments can be derived from any rock type, including rocks enclosing caves and originating outside of caves (Fig. 1), as well as secondary deposits such as travertine.Clastic sediments are volumetrically the most …Tufa and Travertine. Calcite can form chemical sedimentary rocks on land in a number of environments. Tufa forms at springs. The tufa towers in Figure 9.11 formed where spring water discharged into lake water.
