17, 2021 · Kimberlite pipes are igneous stones, or stones that formed from molten magma, and can found under the surface of the soil. Naturally occurring diamonds are mostly found in these kimberlite pipe deposits. If your crystal was originally sourced from a kimberlite pipe, there's a greater likelihood that it is a diamond rather than another stone.

properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Basalt like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Basalt rock are vital in determining its Basalt Texture and Basalt Uses.
How to identify kimberlites: Kimberlites commonly have high titanium, chromium, nickel and magnesium values in overlying residual soils. Mineral chemistry is used extensively to help determine whether the kimberlite source is diamondiferous or barren.
Once a kimberlite is identified, subsequent work is aimed at determining the economic parameters of size, grade, value, and potential mining cost. The evaluation of a diamond deposit is the process followed to establish economic viability, and in some cases, to identify the "footprint" of the deposit.

Kimberlite is the name given to a silica-poor and magnesium-rich extrusive igneous rock (, a volcanic rock) that contains major amounts of olivine, often Kimberlite may occur in the field as dikes or pipes that crystallize near but below the surface (hypabyssal kimberlite) or as magmas that
Kimberlite pipes are often only a few hundred meters across so from a geologic standpoint it wouldn't take much to completely obliterate it. Distribution of kimberlites worldwide in relationship to Archaean cratons. While this diagram shows a good correlation between cratons and kimberlites,
Group I kimberlites Group- I kimberlites are of CO2-rich ultramafic potassic igneous rocks dominated by a primary mineral assemblage of forsteritic Kimberlites magmas rise from depth through narrow ~1m thick fissures. The kimberlite magma is focused along structural faults which act as focuses
The first Kimberlites were described by Vanuxen in 1837 from Ludlowiville near Ithaca, New York state; however, the term Kimberlite was introduced Kimberlites are highly magnesian (MgO > 25% weight) magmatic rocks which are enriched in volatiles (water, carbon dioxide, and fluorine) and
Most kimberlites have a distinctive aeromagnetic signature—in general, a roughly circular anomaly. How-ever, at ground level the anomaly is more complex, and it We propose using a simple pattern recognition technique, based on the analytic signal of the magnetic eld to identify kimberlite targets.
