Plain Language Summary
Large igneous provinces (LIPs) represent enormous volume of magmas (>0.1 MKm³) produced within a short duration (∼1–5 Ma). The involvement of fluids in generating LIPs remains equivocal. Some studies suggest that water plays an important role, whereas the others argue against this model, based on the typical anhydrous mineral...
Long-lived collisional orogens that formed over tens to hundreds of millions of years are common in the geologic record. The Trans−North China orogen marks the collision between the Eastern and Western blocks of the North China craton, and it preserves metamorphic rocks with ages between 1.98 Ga and 1.80 Ga. These units allow detailed assessment of...
The Narmada‐Son lineament is a major tectonic feature in Central India.
