There are two types of diamonds: gem diamonds and industrial diamonds. The diamond is found in igneous rocks called kimberlite. It is a mineral c...Kimberlite is classified into three types based on its characteristics and location. Kimberlite is formed by magma eruptions from deep within the earth's mantle. Although the exact process of how kimberlite magma rises or forms is still not understood by scientists, geologists have identified three main facies: ...For example, as pressure drops during ascent, the kimberlite magma is not able to dissolve as much carbon dioxide, and a fluid rich in carbon dioxide and water exsolves from the magma. (figure 1; Brey and Ryabchikov, 1994). This fluid, which often dissolves diamond, normally starts to exsolve at around 3–4 GPa (a giga­pascal is a unit …Map shows location of kimberlite intrusives and the major structural elements underlying Pennsylvanian and Permian sediments.

Kimberlite doesn’t form like many rocks do, as layers in the crust over a location. Instead, kimberlite is known to form kimberlite pipes. A frequently proposed model for cratonic lithosphere destruction, based on the apparent link between kimberlite locations and hotspots, is the thermal-magmatic erosion (Foley, 2008) or its recent equivalent, plume-triggered delamination (Hu et al., 2018), which involves plume activities, kimberlite magmatism, and subsequent delamination of ...According to Drugs.com, pulse points are located throughout your body.
