“…The Deccan Traps is a late Cretaceous-Paleogene continental flood basalt province covering more than 500,000 km 2 of peninsular India (Kale, Dole, et al, 2020;Krishnamurthy, 2020a, and references therein;Mahoney, 1988;Manu Prasanth et al, 2019;Verma & Khosla, 2019). The Deccan Traps mark the beginning of the Réunion hotspot track and are associated with partial melting due to the arrival of a deep mantle plume under the Indian subcontinent (presently beneath Réunion; e.g., Richards et al, 1989); see Peters et al (2017) for discussion of isotopic evidence).…”

The underground storage of CO2 (carbon dioxide) in basalt presents an exceptionally promising solution for the effective and permanent sequestration of CO2. This is primarily attributed to its geochemistry and the remarkable presence of reactive basaltic minerals, which play a pivotal role in facilitating the process. However, a significant knowledge gap persists in the current literature regarding comprehensive investigations on the reactivity of basaltic minerals in the context of CO2 sequestration, particularly with respect to different basalt types. To address this gap, a comprehensive investigation was conducted that considered seven distinct types of basalts identified through the use of a TAS (total alkali–silica) diagram. Through a thorough review of the existing literature, seven key factors affecting the reactivity of basaltic minerals were selected, and their impact on mineral reactivity for each basalt type was examined in detail. Based on this analysis, an M.H. reactivity scale was introduced, which establishes a relationship between the reactivity of dominant and reactive minerals in basalt and their potential for carbonation, ranging from low (1) to high (5). The study will help in choosing the most suitable type of basalt for the most promising CO2 sequestration based on the percentage of reactive minerals. Additionally, this study identified gaps in the literature pertaining to enhancing the reactivity of basalt for maximizing its CO2 sequestration potential. As a result, this study serves as an important benchmark for policymakers and researchers seeking to further explore and improve CO2 sequestration in basaltic formations.

“…Their results suggest a long‐lived thermal event possibly related to the input of radiogenic heat. Manu Prasanth, Hari , and Santosh (—this issue) provide an overview of the Deccan large igneous province (DLIP) of Peninsular India, predominantly composed of tholeiitic basalts with a minor amount of alkaline, carbonatite, and silicic rocks. The mineralogical and geochemical data suggest that these rocks were derived from a mantle plume with extensive assimilation of crustal components.…”
