Granitic Magmatism in the SouthEastern Part of Central Indian Tectonic Zone: A Review with Emphasis on the Bilaspur-Raigarh Belt
Year: 2025
Type: article
Abstract: The Central Indian Tectonic Zone (CITZ) is a notable Proterozoic tectonic zone that came into existence after the amalgamation of North and South Indian Blocks, recording the events of the Mesoproterozoic Grenvillian orogeny and the assembly of the Rodina supercontinent. The Bilaspur Raigarh Belt (BRB), located in the eastern part of CITZ, consisting of granite, gneiss, and metasedimentary rocks, including slate, phyllite, and schist, which is a relatively under-researched belt. This review-based study presents the current status and consolidates the knowledge of granitic magmatism in the BRB, emphasizing its litho-tectonic assemblages. The BRB granitoids vary from tonalite to granite, displaying metaluminous to peraluminous compositions with I- and S-type characteristics generated by melting heterogeneous sources at different depths. This study highlights the necessity for additional research to clarify the tectonic evolution of the BRB within the CITZ.
