What is a kimberlite
Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently. Aluminium Oxide, NaCl, CaO, Iron (III) Oxide, FeO, Potassium Oxide, MgO, MnO, Sodium Oxide, Silicon Dioxide, Titanium Dioxide. Kimberlite and hot blobs. Kimberlite eruptions leave behind a characteristic deep, carrot-shaped “pipe” of kimberlite rock, which often contains diamonds. Hundreds of these eruptions that occurred over the past 200 million years have been discovered around the world. Most of them were found in Canada (178 eruptions), South Africa (158 ...With kimberlite mines, the big holes can be filled up with water to create new lakes. These new lakes can become spots for fish to live and birds to visit. Plus, they offer a peaceful place for people to enjoy nature. Besides just water, the land around these old mines can be given a green touch.

The West Coast of Namaqualand in South Africa hosts extensive detrital diamond deposits, but considerable debate exists as to the provenance of these diamonds. Some researchers have suggested derivation of the diamonds from Cretaceous-Jurassic kimberlites (also termed Group I kimberlites) and orangeites (also termed Group II …Kamenetsky et al. (2012) argued that the parental melt of the Udachnaya kimberlite (and possibly of Type I kimberlites worldwide) was a halogen-rich Na Ca carbonatite, which progressively assimilated silicate components to form kimberlite magmas. All these melts intruded host mantle and metasomatized it.1980 close-up image of the razor-sharp kimberlite/granite contact in the Schaffer Kimberlite complex. Kimberlite “blue ground” (left) intruded into sheared Sherman Granite (right). The first diamond discovery in the Wyoming Diamond Province came from the Schaffer 3 kimberlite in 1975.Kimberlite magmas tend to be volatile, erupting at speeds of more than 100 feet per second (30 meters per second) and pulling diamonds from the surrounding rocks as they go. In this way, gemstones ...Aug 3, 2016 · This means that total kimberlite occurrences are tens of thousands of hectares of land-mass, compared to 13 billion hectares of land on the planet, of which 7% is located within Archean cratons . Given that less than 1% of kimberlites will yield an economically-viable diamond deposit, finding a viable diamond mine is a daunting task.
The 3-021 kimberlite is very similar to the 3-016 kimberlite both petrologically and also indisposition. The 3-021 kimberlite is located 1 kmnortheast of P-11 kimberlite and 3.5 km WSW ofP-10 kimberlite.
