Age and petrogenesis of mafic granulites from central Madurai block, south India: implications on regional tectonics

Autor: J Amal Dev, JK Tomson, T Vijaya Kumar, Nilanjana Sorcar

Publikováno v: Geological Magazine. 160:955-971

The Precambrian Southern Granulite Terrane (SGT) of south India is well-known for the preservation of high- to ultrahigh-temperature (HT-UHT) granulites, prominently exposed in its central part forming a linear belt referred to as the Kambam UHT belt

Petrochronological appraisal on the timing and duration of ultrahigh-temperature metamorphism in southern India: Insights from charnockite and sapphirine bearing semipelitic granulites from the Madurai Block

Autor: Ashish Kumar Tiwari, Tapabrato Sarkar, Nilanjana Sorcar, Sneha Mukherjee

A robust temporal constraint on the timing and duration of metamorphism is paramount for correctly interpreting the geodynamic evolution of orogenic belts. The Madurai Block of the Southern Granulite Terrane, India has garnered much attention on acco

Evidence of high-pressure metamorphism along the Mahanadi Shear Zone in the Eastern Ghats Province, eastern India: implications on tectonics and continental assembly involving India and East Antarctica

Autor: Shuvankar Karmakar, Sankar Bose, Gautam Ghosh, Nilanjana Sorcar, Sneha Mukherjee

Mafic granulites occur as enclaves within host mylonitized felsic rocks along the WNW-ESE trending, northerly dipping (40°-80°) Mahanadi Shear Zone (MSZ) of the Eastern Ghats Province (EGP), eastern India. Mafic granulite enclaves are characterized

Petrological characterization of the Cryogenian lower crust of southern India: Evidence from charnockites and metapelites from the northern part of Madurai Block

Autor: Arpita Singha, Ashish Kumar Tiwari, Tapabrato Sarkar, Nilanjana Sorcar, Sneha Mukherjee

The granulite terrane of southern India exposes Precambrian granulites that are dismembered into several crustal blocks with intervening shear/suture zones. Madurai Block forms the largest crustal block, preserving rock record from the Neoarchean to

Neoproterozoic Mafic Magmatism in Nagercoil Block, Southern India and Its Implications on the Gondwana Collisional Orogeny

Autor: S. Sajna, J. K. Tomson, J. Amal Dev, Nilanjana Sorcar, T. Vijaya Kumar

Publikováno v: Minerals; Volume 12; Issue 12; Pages: 1509

The Nagercoil block situated at the southernmost tip of India occupies a key position in the East Gondwana collisional tectonic models. The Nagercoil block is dominated by Orosirian I-type charnockite massifs that host numerous gabbroic emplacements.
