Heliotrope (mineral) is Indonesia, especially in Purbalingga district. It is also found in Armenia, Azerbaijan, Brazil, Bulgaria, China, Australia, and the United States. There is also an outcrop of bloodstone on the Isle of Rum, in Scotland. Heliotrope (mineral) The mineral aggregate heliotrope (from Greek ἥλιος, "hḗlios" “Sun”, τρέπειν, "trépein" “to turn”), also known as bloodstone, is a variety of jasper or chalcedony (which is a cryptocrystalline mixture of quartz). The "classic" bloodstone is green jasper (chalcedony) with red inclusions of hematite. The red inclusions are supposed to resemble spots of blood, hence the name "bloodstone". The name "heliotrope" derives from various
Geology applications of Fourier transform infrared spectroscopy Fourier Transform spectrometer due to its high sensitivity. Water is thought to have signifiant role in affecting mantle rheology, either by hydrolytic weakening to the mineral structure or by lowering the partial melt temperature. The presence of hydrous components within NAMs can therefore (1) provide information on the crystallization and melting environment in the initial mantle; (2) reconstruct the paleoenvironment of early terrestrial planet. Inclusion refers to the small mineral crystals and foreign fluids within a crystal. Melt inclusions and fluid inclusions can provide physical and chemical information of the geological environment in which the melt or fluid are trapped
