How does a chemical sedimentary rock form
WebSimply the igneous rocks (which CAN NOT originally contain any FOSSILS) or the sedimentary rocks (which CAN originally contain some FOSSILS) undergo extremely high pressures or/and temperatures. But in these conditions, the structure of the rocks, even if they originally contained some organic material, will be altered. WebA rock formed in a terrestrial environment is conglomerate. It is a coarse-grainedsedimentary rock composed of rounded fragments (> 2 mm) within a matrix of finer grained material. Conglomerate is a sedimentary rock made of rounded pebbles and sand that is usually held together (cemented) by silica, calcite or iron oxide. It is a stone similar ...

WebThe formation of a clastic sediment and sedimentary rocks involves five processes: Weathering - The first step is transforming solid rock into smaller fragments or dissolved ions by physical and chemical weathering as discussed in the last lecture. Erosion - Erosion is actually many processes which act together to lower the surface of the earth. WebSedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water.
