Clastic rock - Wikipedia
Clastic sedimentary rocks are rocks composed predominantly of broken pieces or clasts of older weathered and eroded rocks. Clastic sediments or sedimentary rocks are classified based on grain size, clast and cementing material composition, and texture.
6.1: Clastic Sedimentary Rocks - Geosciences LibreTexts
2024年4月24日 · The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise, it is mudstone. Mudrocks form in very low ...

2024年8月22日 · 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 of clastic sedimentary rocks are summarized in Figure 9.5.
5.5: Classification of Sedimentary Rocks - Geosciences LibreTexts
2024年4月11日 · Clastic (or detrital) rock is classified and named based on the size and composition of the clasts. Their various sizes, from boulders to clay, is referred to as the sediment grain size. The classification and description of the various clastic rocks appears in the top section of the chart below.
Clastic Rock - an overview | ScienceDirect Topics
Clastic rock is defined as a type of rock formed through the erosion, transportation, deposition, compaction, and diagenetic processes of rock components. Typical examples include conglomerate, sandstone, siltstone, shale, and claystone.
Sedimentary rock | Definition, Formation, Examples,
2024年10月30日 · Clastic terrigenous sedimentary rocks consist of rock and mineral grains, or clasts, of varying size, ranging from clay-, silt-, and sand- up to pebble-, cobble-, and boulder-size materials. These clasts are transported by gravity, mudflows, running water, glaciers, and wind and eventually are deposited in various settings (e.g., in desert ...

In Silurian Period: Clastic rocks. Clastic rocks, including conglomerates, sandstones, and shales, generally occur in wedge-shaped deposits adjacent to land areas from which terrigenous materials (items derived from the erosion of land) erode under conditions of moderate to high annual rainfall.

6.1 Clastic Sedimentary Rocks – Physical Geology
In this book, coal is classified with the clastic rocks for two reasons: first, because it is made up of fragments of organic matter; and second, because coal seams (sedimentary layers) are almost always interbedded with layers of clastic rocks, such as mudrock or sandstone.
