WebbThe south-eastern Gorny Altai is one of the most hazardous seismogenic area in the north of Central Asia. We present a synthesis of field, 230Th-U geochronological, mineralogical and geochemical data collected on seven Quaternary travertines. All travertines occur within the zones of active faults that border the Chuya and Kurai intermontane basins. … WebbConglomerates are rocks containing coarse rounded clasts, and breccias contain angular clasts (see figure). Both conglomerates and breccias are usually poorly sorted. Figure 5.3. 1: Enlarged image of frosted and rounded windblown sand grains Medium-grained rocks composed mainly of sand are called sandstone, or sometimes arenite if well sorted.

WebbSome of the coloration in breccia comes from its cement. There are three primary cement types: silica, calcite, and iron oxide. Silica and calcite are general very light in color or even colorless. They are also the most common types of cement. Iron oxide, however, is rust-red and often stains the breccia to match.
