In this article we are going to explain one of the most striking stones that appear in nature, the Dalmatian jasper. Here you will learn all the properties, characteristics, meaning and uses of the stone. Traditionally, the Dalmatian jasper stone is defined as a colorful “gem” that combines small black or dark brown spots distributed […]

In geology, kimberlite is described as a magmatic or igneous rock with a high magnesium content (MgO greater than 25% by weight), therefore it is considered a variety of rock belonging to the peridotite group. Thus, kimberlites are ultramafic intrusive igneous rocks. The first kimberlites discovered were described in 1837 by Vanuxen from Ludlowiville near

The salt rock or also known as rock salt It belongs to the fascinating group of chemical sedimentary rocks that are formed by processes of evaporation of waters enriched in mineral salts, in arid and semi-arid environments, oceanic waters and saline lakes. It is also known by the name of halite ore, in fact rock

Coal is one of the most important fossil fuel materials today because it generates more than 40% of all electrical energy on the planet. This is thanks to its great energy power and its relatively easy extraction. In this article you will learn all the important information about this organic sedimentary rock, its characteristics and

Volcanic rocks are those that originate from the rapid or sudden cooling of lava or volcanic material that is expelled on the surface of the earth’s crust, from volcanic eruptions that can become very explosive, which is why they are also known as rocks. extrusive igneous. Volcanic rocks are directly related to volcanic activity (volcanoes)

The caliche is a rock that is formed by the cementation of particles found in the layers of the soil, for this reason, it is usually similar to a layer in the soil, but very compact. Visually it is very similar to conglomerate, breccia and sandstone, but it must be remembered that this rock has

Flint is a very resistant rock or stone with a history in humanity, because it was used to create tools and even the rarest specimens were used as precious stones. The term flint corresponds to a chemical or biochemical sedimentary rock that is characterized by being very hard and resistant, and because when it breaks

Lignite is the second type of coal that forms after peat, therefore it is an organic sedimentary rock, but due to its physical and chemical characteristics it does not usually have many important uses. In this article you will learn all the properties and uses that lignite has. What is lignite rock? Lignite is an

Currently, the use of coal is mainly to generate electricity and as a fossil fuel in different industries, because it is a cheap and efficient fuel, in addition to the fact that all the waste it generates can be adequately controlled. In fact as data, in the United States around 91.8% of all the coal

Chert is the general term for fine-grained siliceous sedimentary rock of biogenic, biochemical, or chemogenic origin. It is made up of fine-grained silica, with only trace amounts of impurities. By contrast, modern siliceous sediments can have a high proportion of impurities, either biogenic carbonate or siliciclastic muds. Extremely pure siliceous oozes are relatively rare deep-water
