- Amphibole of metabasites in the Lesser Himalaya of Nepal
説明
The Lesser Himalaya in central Nepal exposes an inverted metamorphic sequence. The metabasites in the sequence occur as sheet-like bodies of a meter to tens of meters thickness. All the samples studied have the mineral assemblage Amp+Ab+Ep+Qtz+Titanite±Magnetite. Amphiboles occur as (1) sheared and elongated porphyroclasts with asymmetric pressure shadows and overgrown rims, (2) acicular and bladed aggregates parallel to the foliation and (3) inclusions in plagioclase. Amphibole chemistry suggests that (i) the peak metamorphism was attained during shearing related to the MCT movement and (ii) the peak thermal structure is inverted in the MCT shear zone.
