Many rocks contain minerals that contain metallic elements. Rocks that contain metallic elements that can be economically refined into quantities of useful metals are called metallic ores. Bauxite, for instance, is the common rock ore which is refined to produce the metal aluminum.
Diamonds are typically formed from carbon that has been subjected to high pressure and temperature deep within the Earth's mantle. The parent rock of diamonds is believed to be a type of igneous rock called kimberlite or lamproite, which are formed from magma that originates from the mantle.
The C horizon typically contains parent rock material, which is the unweathered rock from which the soil has developed.
Diamonds ascend to the Earth's surface in rare molten rock, or magma that originates at great depths. Carrying diamonds and other samples from Earth's mantle, this magma rises and erupts in small but violent volcanoes. Just beneath such volcanoes is a carrot-shaped "pipe" filled with volcanic rock, mantle fragments, and some embedded diamonds. The rock is called kimberlite after the city of Kimberley, South Africa, where the pipes were first discovered in the 1870s. Another rock that provides diamonds is lamproite. The extraction process can take place at the mine site, where the excavated material is washed and tumbled. Because diamond is heaviest of all the materials mined, it falls to the bottom and is otherwise sorted from the mined materials.
Various objects come from rocks, such as gemstones (like diamonds or rubies), building materials like marble or granite, metals like gold or iron, and salt. Rocks can also be used for landscaping, sculptures, and even in medicinal treatments like from minerals.
kimberlite
No. Kimberlite is an igneous rock best known for sometimes containing diamonds. it contains no quartz crystals at all.
Diamonds are found in rayer types of igneous rocks known as "Kimberlites"credit to Alberto Vacca
Kimberlites are the rock type that diamonds are usually found in. They are formed when a magma from deep in the mantle drills its way to the surface in a fast gaseous explosive event. Diamonds typically occur as xenocrysts within the Kimberlite matrix. the volcanic deposits are called Lamproite igneous volcanic pipes. Please see the related links.
Kimberlite
Diamonds are the hardest rock.
potassic volcanic rock best known for sometimes containing diamonds
Diamonds are sometimes referred as a rocks because of their shape before they are cut for jewelery
Kimberlite is what geologists call "ultrabasic" rock because it does not contain quartz or feldspar. Those are the two most common rock-forming minerals.
all you do is dig to bed rock and then count blocks up sometimes they is diamonds then you dig in any direction
Diamonds are made from carbon, and are called rocks sometimes in their raw, natural form.
Apparently kimberlite pipes -- that can contain diamonds -- are volcanic formations that begin deep within the earth's mantle. Because diamonds and kimberlite -- and other semi-precious gems -- are formed in similar locations, some kimberlite rock contains diamonds. You can read more, below.
