As the magma nears the surface, the decrease in pressure causes it to cool rapidly, solidifying into igneous rocks. These rocks, known as volcanic or hypabyssal rocks, contain the diamonds transported from the mantle. kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix. It has a porphyritic texture, with large, often rounded crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass). Both peridotite and eclogite contain diamonds, but intact peridotites erupted to the surface with their diamonds in place are rare, while eclogites with their diamonds in place are common. (For a detailed description of rock type, see Kirkley et al., 1991.)There are many factors to consider when trying to find the best layer to find diamonds.

One of these locations is the Lamproite Belt in Australia, where diamonds have been found in lamproite stones. Lamproite is thought to form when mantle-derived magmas interact with metasedimentary rocks in the upper crust.This type of lamproite is also diamond-bearing, though somewhat less common than breccia tuff. A third type, magmatic lamproite, filled pools of lava within the crater during later eruptions. Today it looks similar to breccia tuff but is much harder, with a rounded shape. Magmatic lamproite is not believed to contain diamonds.

Jan 29, 2023 · Porosity: The rock typically has a high porosity, meaning it contains many small voids or spaces. You can observe it under a microscope and identify the real kimberlite. Texture: The stone has a fine-grained texture with a glassy or crystalline appearance. It is a snap way to tell whether it is a kimberlite.

Crater facies kimberlites contain pyroclastic fall back breccias or epiclastic water–lain material. The lacustrine sediments of the craters are sometimes affected by subsidence, perhaps of a cauldron nature. 1.3 Mineralogy Kimberlites may be defined as a potassic ultrabasic hybrid igneous rock containing large
