When water is very still. 2 categories of Sedimentary Rocks. Clastic and non-clastic. clastic sedimentary rock. Rock fragments that have been cemented together. Breccia ingredients. Angular pebbles- edges are pointy which means they didn't travel far. Breccia- EOD. Fault zones, alluvial fans.Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20-25% of all sedimentary.You can determine whether a clastic sedimentary rock, like a sandstone, is cemented with calcite by adding a drop of dilute acid to a fresh surface on the sample. If the sample reacts readily with the acid, it is likely cemented by calcite. Figure 5.3.4: Lithification turns sediments into solid rock. Lithification involves the compaction of ...The effects of chlorite on tight sandstone reservoirs have not been fully understood yet.

Fine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it is called shale. Otherwise, it is siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay).
