What is kimberlite

Lab-grown diamonds are absolutely real in the sense that the resulting stone is a gem-quality diamond that can compete with natural stones in many ways. They sparkle and catch the light. They’re ...

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 bodies include volcanic pipes and sheet-like or tabular bodies. Most tabular kimberlite bodies are intrusive sheets (Fig. 5c) which can be described as vertical, horizontal or inclined and referred to as dykes and sills when determined to be discordant or concordant, respectively. Other sheet-like bodies could occur and include ...The MZ and Doyle kimberlites are also in close proximity to Kennady North (Fig. 2), and best described as shallow dipping kimberlite dykes. The Snap Lake kimberlite is a diamondiferous dyke intrusion located approximately 62 km west of Kennady North and also of similar age at approximately 537 ± 11 Ma (after Agashev et al. 2008).Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not ...Lake Ellen Kimberlite. Coordinates: 46°10′29″N 88°10′36″W.

Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person.

The central Lac de Gras (LDG) kimberlite field, which contains the Diavik and Ekati Diamond Mines, was principally active from 75 to 45 Ma (Cretaceous to Eocene) (Sarkar et al. 2015). The LDG field is located east of the inferred craton suture (Fig. 1). Its kimberlite pipes define a 100-km by 200-km northwest-trending zone (Lockhart et al. 2004).Kimberlite occurs in the Earth's crust in vertical structures known as kimberlite pipes which are the most important source of mined diamonds today. Kimberlites ...Kimberlite 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.The answer lies in some of the oddest and rarest volcanoes on the planet.

Kimberlite is an igneous rock, which sometimes contains diamonds.Kimberlite pipes are the most important source of mined diamonds today. The consensus on kimberlites is that they are formed deep within the mantle.

Kimberlites can be categorized into four types in terms of their relationship to electrical conductivity distribution in the mantle. Kimberlites tend to be emplaced on hydrated/metasomatized lithosphere and avoid both dry/depleted and heavily metasomatized/very conductive parts of the lithosphere.The discovery of kimberlite's carbon-zapping powers was made about five years ago, while De Beers has been doing on-the-ground tests at its Canadian and South African mines for the past two ...kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix.

The surface area of diamond-bearing kimberlite pipes ranges from 2 to 146 hectares (5 to 361 acres).Kimberlites are igneous rocks that represent the deepest magmas originated from the mantle (> 150 km) and typically occur within cratons. Studies of kimberlites ...Some kimberlites have no special crater shape or depression to aid prospecting, but the kimberlite weathers to a yellowish soil. Where excavated, the "yellow ground" gives way at depth to fresher "blue ground", and deeper still, to the unaltered dark greenish-brown kimberlite.Volatile-rich kimberlite magmas may be transported to the surface by broad mantle upwellings located above mobile basal mantle structures, according to global models of mantle convection over the ... ….

The first kimberlites were discovered in Kansas in the late nineteenth century; at first, these kimberlites weren't recognized as igneous rocks (Brookins, 1970a). Several more kimberlites were identified in the 1930's and 1950's (Tolman and Landes, 1939 ...Kimberlite eruptions have never been witnessed, because most kimberlites were formed millions to billions of years ago.
