Calcite grains range from 50 μm to 3 cm in size; in contrast to the saccharoidal calcite, larger grains are strongly deformed, aligned with the foliation and contain abundant primary micro-inclusions of celestine and Sr-rich anhydrite, whose identity was confirmed by Raman spectroscopy.

"WebbStudy of geological materials with Raman Spectroscopy The term inosilicates is used for chain silicates. They are divided in two groups: pyroxenes and amphiboles. Pyroxenes contain single chains of SiO 4 groups. Like jadeite, their spectra present an intense Raman band between 650 and 700 cm-1[2]. " - The raman study of amphiboles

Webb4 feb. 2010 · Abstract Abstract— We studied micro Raman spectroscopy of amphiboles and pyroxenes in the martian meteorites Zagami and Lewis Cliff (LEW) 88516. The obtained Raman spectra of the amphiboles are similar to those of kaersutite, reconfirming the previous studies that they are kaersutitic amphiboles enriched in Ca, Al, and Ti. WebbThese studies demonstrated that the textural parameters of the parent granodioritic source lithotypes represent the main control on rock-fragment abundance in modern plutoniclastic sand (Heins 1993), and that the types, and durability, of mineral interfaces, preserved inside the felsic sandy phanerites, are closely related to climate and topography of the source …
