Mineral chemistry and geothermobarometry of metabasites of the Majerad igneous-metamorphic complex (SE of Shahrood)

Journal of Economic Geology, 2020
Introduction Thermobarometric models based on the chemical equilibrium among coexisting mineral-mineral or mineral-melts pairs are useful tools widely used to estimate the P-T path and chemical evolution during igneous processes. The high sensitivity of

The Chemical Composition of Garnet for Sedimentary Provenance Determination, North Coast of Rio de Janeiro State, Brazil [PDF]

Anuário do Instituto de Geociências, 2018
The chemical composition of garnet, together with the analysis of the heavy minerals and their textures, is an important tool for accurate sedimentary provenance studies. The coastal segment of Northern Rio de Janeiro State, limited by the deltas of the

Multi-Analytical Approach for Identifying Asbestos Minerals In Situ

Geosciences, 2018
An innovative and, as yet, untested approach is to analyze serpentinite and metabasite rocks containing asbestos using a portable multi-analytical device, which combines portable digital microscopy (p-DM), portable X-ray Fluorescence (p-XRF) and portable

Interpretation of the Metamorphic Processes in Various Rock Types Using the Chemistry of Garnets (Selecka Mountain, Macedonia)

Geologia Croatica, 2010
The garnets from the complex of Selecka Mountain could be divided in two groups on the basis of their chemical composition and zoning.The garnets from muscovite-schist and amphibole-schist show characteristics typical for a growth in prograde metamorphic

Geochemistry, Lu–Hf garnet ages, and P–T conditions of blueschists from the Meliatic and Fatric nappes, Western Carpathians: Indicators of Neotethyan subduction

Geosystems and Geoenvironment, 2023
Basaltic rocks from ophiolitic mélanges provide information on geodynamic setting, origin, and later tectonometamorphic conditions. This paper resolves the P–T conditions and timing of high-pressure metamorphism in an accretionary wedge that formed ...
