The raman study of amphiboles
Webbamphiboles are also common. 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.

WebbVariations in the salinity of black smoker effluents (0.1–∼ 8 wt.% NaCl) relative to seawater (3.2 wt.% NaCl) are attributed to phase separation and segregation of the resulting brines and vapors. However, models of phase separation predict brines with substantially higher salinities than observed at vents and such brines are commonly observed in fluid … Webb17 maj 2024 · We present the results of a comprehensive study linking the crystal-chemical formulae of amphiboles, a series of extremely complex silicates with the general …

WebbThe use of heavy minerals as a stratigraphic tool in the study of loess sequences from NW Europe originated some 70 years ago. One major problem in using the available data sets is the heterogeneous stratigraphic context of the samples, given the complex historic evolution of the stratigraphic framework of loess sequences.
