Full of various Crystals/gemstones-the darker chunks stuck in the concretion is kimberlite. Found in the volcanic region of Missouri, St Francois MountainsKimberlite rocks and deposits are the eruption products of volatile-rich, silica-poor ultrabasic magmas that originate as small-degree mantle melts at depths in excess of 200 km. Many kimberlites are emplaced as subsurface cylindrical-to-conical pipes and associated sills and dykes. Surficial volcanic deposits of kimberlite are rare.

What is Kimberlite? Kimberlite is a volcanic rock that is known for containing diamonds. This igneous rock is generated deep within the Earth's mantle and is brought to the surface by explosive volcanic eruptions.

This article will introduce the rock and describe the benefits of kimberlite as a ...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.

Kimberlites are often closely associated, both in time and space, with a wide variety of alkaline ultramafic rock types, yet the question of a genetic relationship between these rock types remains uncertain. One locality where these relationships can be studied within the same cluster is the Karelian craton in Finland.

Kimberlites are very […]Kimberlite is a soft, dull-gray rock with thin white veins that originates deep in the earth, in the upper mantle—the layer that lies about 25 to 250 miles beneath the earth's surface. As kimberlitic magma erupts, it expands, breaking up rock in its path and exploding through the crust (perhaps at speeds of 1,300 feet per second).Kimberlite | rock “Kimberlite occurs in the uplifted centres of continental platforms.

Transported by rivers and streams, these diamond crystals end up in river gravel beds and silt often at great distances from their original source. Until the late 1800s, the world's diamonds were found and collected from these alluvial beds. Today, most diamonds are found in kimberlite pipes, which are the primary source of mined diamonds.

Kimberlite magmas are volatile-rich, silica-poor ultrabasic magmas originating as small-degree mantle melts at depths of 150 km or greater. Alteration and entrained xenoliths obscure their original magma chemistry and properties. Kimberlite magmas decrease temperature by a few hundred degrees during ascent. Changes of melt composition can result as a function of assimilation. Stalling of ...
