INTRODUCTION, PART‐1—Geodynamic evolution of Eastern Himalayan and Indo–Myanmar orogenic belts: Advances through interdisciplinary studies

Abstract

This Special issue covers research articles of interdisciplinary studies of geosciences to understand the magmatism and exhumation history of the crystalline core, pressure, temperature, time, and deformation (P–T–t–d) conditions of the geologically least explored eastern Himalaya and Indo–Myanmar Orogenic belts and adjoining regions. It has the potential to become a reference volume for researchers particularly working in the Eastern Himalaya, Shillong Plateau, Assam‐Arakan Basin, and Ophiolites of Northeast India, including the Andaman Ophiolites. Although there remains a lot still to cover the entire area of the proposed region, this volume will be useful to future researchers and will also have the potential to become a reference volume for researchers particularly working in the north‐eastern part of India and adjoining regions.

Introduction, Part 2—Geodynamic evolution of Eastern Himalaya and Indo‐Myanmar orogenic belts: Advances through interdisciplinary studies

“…The Neo‐Tethyan ophiolites of the TTSZ, EH (viz. Tidding Ophiolite Complex and Mayodia Ophiolite Complex) IMOB, that is, Nagaland Ophiolite Complex and Manipur Ophiolite Complex which lie along the southern extension of the ITSZ have been collectively investigated by Singh, Chung, and Somerville (2022a, 2022b) through the mantle‐derived peridotite sequence. They have proposed that the mantle peridotites of TTSZ and IMOB underwent multiple episodes of partial melting, depletion, enrichment, and refertilization processes during the evolution of the Tethyan oceanic lithosphere, at a tectonic setting that changed in time from a mid‐oceanic ridge to a forearc spreading setting, that suggest a pre‐subduction and subduction origin of these investigated ophiolites.…”

“…The MCT marks significant variation in structural geometry along its length (Biswal, 1997; Singh & Thakur, 2001). A recent review on tectonics of eastern Himalaya can be found in the recent special volume (Singh, Chung, & Somerville, 2022) in the Geological Journal .…”
