How is carbonaceous shale formed? What is its performance? What is it for

A type of clay rock. In addition to clay minerals (such as kaolinite, montmorillonite, mica, Baillite, etc.), it also contains many clastic minerals (such as quartz, feldspar, mica, etc.) and autogenous minerals (such as iron, aluminum, manganese oxides and hydroxides). It has a page-like or lamellar bedding.

It is easy to break into pieces when hit with a hard object. It is a rock formed by the extrusion of clay in the movement of the earth's crust. It is a sedimentary rock that is formed by the extrusion, dehydration, recrystallization, and cementation of weakly consolidated clays.

It is called shale because it is well-layered and easy to peel. Shale is generally brown, gray or black in color and does not have a high degree of hardness. Shale is divided into siliceous shale, calcareous shale and carbonaceous shale according to its different content of silicon, calcium and carbon.

Carbonaceous shale. It contains a large amount of carbonized organic matter, which is commonly found in the roof and floor of coal measure strata.

Used in cement can reduce costs, enhance activity, increase compressive strength, and reduce fuel costs. With a calorific value of 1300-3600 kcal, it can be used as a substitute for coal to generate electricity.

Carbonaceous shale is a type of shale with a large amount of dispersed carbonized organic matter. Carbonaceous shale can stain hands, but it contains ash.

high, so it is not easy to burn. It is often formed in lake-swamp environments and symbiotically with coal seams.

There is a saying of high-carbonaceous shale, but there is no such thing as carbonaceous shale.

Carbonaceous mudstone refers to mudstone containing carbonaceous components, and the general organic carbon content is about 10% to 30%. "Mudstone", also known as claystone, is mainly composed of fine particles with a particle size of less than millimeters, and its main branches are composed of clay wild minerals, followed by quartz, muscovite and a small amount of feldspar. Common clay minerals are kaolinite, mica, montmorillonite, etc.

The structure of carbonaceous mudstone is complex, with two types: clastic structure and grain structure. The detrital structure is mostly composed of particles, mud matrix and bright crystalline cement. Grains, also known as granular chips, mainly include internal debris, biological detritus and oolitic grains, etc., the mud crystal matrix is a plaster composed of calcium carbonate fines or crystals, and the particles are mostly less than millimeters, and the bright crystal cement is a chemical precipitate filled in the pores between the rock particles, and it is a calcite crystal particle with a diameter greater than millimeters; Grain structure is a trapped crystal particle formed by chemical and biochemical precipitation.

1. Most geologists, even those like Werner and Buffon, believe that it takes at least tens of thousands of years for the formation of sedimentary rocks in the earth's crust.

Sedimentation rate analysis: The Nile delta was studied by Herodotus as early as the fifth century BC. Based on the annual rate of sediment deposition, he frankly deduced that the delta must have been thousands of years old.

Later, especially in the late 19th and early 20th centuries, the age of the earth was calculated based on the maximum thickness of the sedimentary rocks and the rate of sedimentation. Since the formation of the Earth, sedimentary rocks are estimated to have been deposited 33,000-100,000 meters thick, while estimates of sedimentation rates vary considerably, from 50-3000 meters per million years. The Earth's age is estimated to be between 17 and 1584 million years.
