Chondrules are peculiar rounded granules of some mineral, usually enstatite or chrysolite, found imbedded more or less abundantly in the mass of many meteoric stones, which are hence called chondrites. Research Chondrules
Enstatite is a common and widespread mineral with a relative hardness of six. It is found in mafic plutonic and volcanic rocks and often in both metallic and stony meteorites. It is a silicate of magnesium and iron and has the formulae Mg2Si2O6. Enstatite has various uses depending upon the quality of its crystals, and is used as a gemstone and for lining ovens, due to its very high melting point. Research Enstatite
Pyroxenes refers to a group of closely related and dark coloured rock forming minerals. Examples are aegirine, diopside, enstatite, hedenbergite, jadeite and spodumene. Pyroxenes are common rock-forming minerals which are found in most igneous and many metamorphic rocks. Their presence in a rock indicates that it crystallised at a high temperature.
