Diamondiferous rock types worldwide are broadly divided into kimberlite and lamproite, the latter of which have unique characteristics in different regions and include carbonate-rich varieties (formerly orangeites/Group II kimberlites).Diamondiferous rocks in West Africa are typically micaceous and share petrographic, mineralogical, and geochemical characteristics with both kimberlites and .

Data from Jacques and others (1989) and calculated free of H2O-.Based on their chemistry, lamproite is either basic or ultrabasic (MgO, 16-23%), with high K2O/Na2O ( 3), high nickel (560-1080ppm) and high chromium (880-1340 ppm) with high concentrations of Rb, Sr, Ba, Ti, Zr, Nb, Pb, Th, U and light-rare-earth elements.These chemical characteristics are derived by melting in .
In 1985, I collected a group of hand samples from one lamproite in the Leucite Hills of Wyoming, and these were processed and examined for diamonds using a binocular microscope.The chances of finding diamonds in such a small sample was very unfavorable (even it they actually occurred in the rock) as large bulk samples measured in tonnes are .

Jun 19, 2016 Also the lamproite diamond ore is much larger at its north end than the south end, the Argyle AK1 lamproite is described as tadpole shape.Another famous lamproite diamond pipe is the Crater of Diamonds, Akansas, US.This also has lots of diamonds but most are so low gemstone quality that the public is allowed to pay to dig .
Kimberlite and lamproite are potassic alkalic ultrabasic igneous rocks with elevated Ba, Co, Cr, Cs, K, Mg, Nb, Ni, P, Pb, Rb, Sr, Ta, Th, U, V and light rare earth elements (LREE).The high Cr, Nb, Ni, and Ta may show up in nearby soils (Jaques 1998), but dispersion of these metals in soils is not extensive.
Kimberlite is just one of several rock types found at the earth's surface that sometimes contains diamonds.More than 40 kimberlites were initially mapped in the Colorado-Wyoming State Line district (1), this was followed by mapping of a small kimberlite blow in the Sheep Rock district (2), a major dike-blow complex in the Iron Mountain district (3), and the mapping of a major lamproite .
Lamproite breccia and tuff as a diatreme.A diatreme is a breccia-filled volcanic pipe formed by a gaseous explosion.
Lamproite from the Ecco Ranch core is internally fractionated in K 2 O, Al 2 O 3 , Ba, MgO, Fe 2 O 3 , Co and Cr most likely by crystal accumulation-removal of ferromagnesian minerals and sanidine.In contrast, the Guess core (305-312 m depth) has little fractionation throughout most of the sill except in several narrow zones.
Lamproite is an ultrapotassic mantle-derived volcanic or subvolcanic rock.It has low CaO, Al 2 O 3, Na 2 O, high K 2 O/Al 2 O 3, a relatively high MgO content and extreme enrichment in incompatible elements.Lamproites are geographically widespread yet are volumetrically insignificant.Unlike kimberlites, which are found exclusively in Archaean cratons, lamproites are found in terrains of .
Lamproite is volcanic rock composed mainly of olivine, clinopyroxene (diopside), mica, leucite, K-amphibole, sanidine.There are many types of lamproite.
Lamproite pipes tend to have a slightly different, funnel-like shape, with relatively shallow craters, usually less than 300 m in depth.In many lamproite pipes, the volcaniclastic facies is intruded by a later magmatic phase that gave rise to lava lakes or domes.

Primarily lamproite but may contain fragments of other native rocks and soil.For many years, the outcropping at the mine was called Kimberlite but in more recent time, it is said to be Lamproite.Both types of rock can contain diamonds and the outcropping at the Crater of Diamonds State Park definitely contains diamonds.
Recognized as olivine-rich lamproite（ Scott-Smith and Skinner, 1984）.Until then, kimberlite had long been regarded as the only primary source of diamonds, and lamproites were considered to bear little scientific and economic importance.The Leucite Hills, Wyoming USA（ Fig.

The genesis of a lamproite pipe: 1.Flared crater formation by erosion of country rock by magma fluids and gases, with development of tuff ring, 2.Crater partially filled with volcanoclastics, 3.Extrusion of lava pond to fill crater.
The lamproite is a dark gray/brown/black.The color difference would be obvious.However, I think the tuff is a prettier sample than the lamproite since it is that great blue color you just don't see that often in rocks.
The lamproite is silica rich and has been postulated to be representative of the magmas which were parental to the Leucite Hills volcanic field.Near-liquidus phases above 5 GPa are pyrope-rich garnet and jadeite-rich pyroxene.Below 5 GPa, jadeite-poor pyroxene is the only near-liquidus phase.

Under these conditions, molten lamproite and kimberlite (commonly known as magma) are also formed within the Earth’s upper mantle and expand at a rapid rate.This expansion causes the magma to erupt, forcing it to the Earth’s surface and taking along with it diamond bearing rocks.Moving at an incredible speed, the magma takes the path with .
