It can found different environmental conditions different color and textures. Siltstone generally are red and gray color with flat bedding planes. Darker colored siltstone have plant fossils and other carbon-rich matter. Tendency to chemical cement. Ash: unconsolidated fragments under. 4 mm. Tuff: consolidated ash. Volcanic Breccia: angular fragments over 4 mm. Agglomerate: large proportion (>25%) of bombs. These rocks are classified on the proportions of vitric, crystal (mineral), or lithic material they contain, for example, "vitric lithic ash," or "crystal ... Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting. Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals.

In contrast, clastic sedimentary rocks with high ICV values indicate primary deposition in an active tectonic environment (Moradi et al., 2016). Black mudstone in Well CY1 has an ICV value ranging from 0.49 to 0.71, averagely 0.65 (Figure 8A; Table 1), indicating high rock maturity. This suggests a provenance of sediment recirculation in an ...Organic-rich mudstone mainly deposited in the semi-deep lacustrine environment, where the water was relatively shallow and the salinity was low, the organic matter was of low abundance and came from the mixed source of plankton and terrestrial clastic (type II 1 –II 2).

The simplest definition is that a mudstone is a fine-grained clastic sedimentary rock that is not laminated or fissile. [5] Most definitions also include a requirement that the rock contain significant amounts of both silt- and clay-sized grains. Clastic sedimentary rocks are named according to the characteristics of clasts (rock and mineral fragments) that comprise them. These characteristics include grain size, shape, and sorting. The different types ……

Mudstone Mudstone is an extremely fine-graineSedimentary rocks can be classified into 5.3.1 Lithification and Diagenesis. Lithification turns loose sediment grains, created by weathering and transported by erosion, into clastic sedimentary rock via three interconnected steps. Deposition happens when friction and gravity overcome the forces driving sediment transport, allowing sediment to accumulate.Sandstone & mudstone are clastic sedimentary rocks that form from the cementing together of sand sized grains & silt sized grains respectively forming a solid ... SEDIMENTARY ROCK TEXTURES. In clastic sediments the sedi Fine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 9.5, bottom row).
