.... 2011 ). However, Rego et al. ( 2012 ) found that size reduction during the PTME was driven mainly by within-lineage change and the extinction of large genera. In this study, we evaluate size variations in Permian foraminiferal suborders across the GLB and PTB. We compiled a database of foraminifer test...

The field relationship along HHC in Siyom Valley showing the folded metamorphic isograd model (drawn from Searly et al, 2008 and references therein).The shaded area shows the zones of partial melting (containing sillimanite + K- feldspar) at Tato and Rego. The isograds have been sheared by ESE directed simple shear. The isograds are flattened to the MCT ductile shear zone as shown in the figure. Below the ductile zone, the MCT brittle fault has a thrusted contact with the LHS at Pene. In the upper part, the right way –up isograd below STD is shown. b. The structural interpretation of the HHC along Siyom valley from Pene to Menchuka in ESE –WNW cross section (looking north). The diagram is not in scale.1. Top-to-ESE upward ductile compressional shear, 2. Boudins, 3. Top-to ESE brittle-ductile compressional shear; MCT: Main Central Thrust; HHC: Higher Himalayan Crystallines; STDS: South Tibetan Detachment System; TH: Tethyan Himalaya; BD: Basal Detachment. The interpretation is based on the surface geology and the extent and geometry of the structures in the subsurface is only based on speculation. The basal detachment inside HHC is based on findings from the other sections (Mukherjee, 2012 and references therein).
