The initial step in sedimentary rock formation is the breakdown of pre-existing rocks and the creation of sediments. This process, known as weathering, can be caused by physical, chemical, or biological agents. Physicalweatheringinvolves the disintegration of rocks due to mechanical forces like tempe...
Sedimentary rock, rock formed at or near Earth’s surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures. Sedimentary rocks are the most common rocks exposed on Earth’s surface but
Sedimentary rock - Clastic, Chemical, Organic: Conglomerates and breccias are sedimentary rocks composed of coarse fragments of preexisting rocks held together either by cement or by a finer-grained clastic matrix. Both contain significant amounts (at le

Sedimentary Petrological Evaluation on Petroleum Reservoir Rocks and Some Examples of this MethodThe main reservoir rocks in giant oil fields of the world are sandstones and carbo-nate rocks. In Japanese oil fields, however, the reservoir rocks are such sedimentary rocks as sandstones (59per cent)...
The properties include the type of the rocks, the age, structures, and other description of the layers. In the system RealModel, a library of properties is specifically created for each geological model, which consists of lists of properties; a list of properties is specifically created for an...
rocks. In addition, many sedimentary rocks contain minerals and fossil fuels that have economic significance. Petroleum, natural gas, coal, salt, phosphorus, sulfur, iron and other metallic ores, and uranium are examples of some of the extremely important economic products that occur in sedimentary...
