The epidote is suggested to have a possible igneous origin, and tobe crystallised from a wet (H2O>5 wt %) magma under low fO2 and intermediate pressureconditions during initial stage crystallisation on the basis of its petrographical andmineralogical characteristics.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:At the base of the Neotethyan ophiolitic melange, widespread epidote crystals formedin metamafic rocks of the metamorphic basement, which were experienced a regionalmetamorphism in green-schist facies conditions.
📊
Key Findings & Data:The epidote crystals is subhedral to euhedral,with high Al2O3 (26-30 %) and low Fe2O3 (5–8%) contents.

Abstract

At the base of the Neotethyan ophiolitic melange, widespread epidote crystals formedin metamafic rocks of the metamorphic basement, which were experienced a regionalmetamorphism in green-schist facies conditions. The epidote crystals is subhedral to euhedral,with high Al2O3 (26-30 %) and low Fe2O3 (5–8%) contents. It is predominantlyzoisite (Xcz = 0.46 to 0.72) and subordinate epidote (Xep =0.27-0.53) in composition, withtypical compositional zoning due to variable substitution of Fe3+ and Al3+ on octahedralsites and sector-zoning. The epidote is suggested to have a possible igneous origin, and tobe crystallised from a wet (H2O>5 wt %) magma under low fO2 and intermediate pressureconditions during initial stage crystallisation on the basis of its petrographical andmineralogical characteristics.
