Medium‐grade metamorphic rocks representing metapelites, calc‐silicates and metavolcanics constitute the rocks of Alwar and Khetri sub‐basins of the North Delhi Fold Belt (NDFB) in southern Haryana and adjacent western Rajasthan. Using modern petrological tools including pseudosection modelling, we describe the metamorphism of the rocks representing these two sub‐basins and show that the reported...
Pseudosections generated using the correctly estimated effective bulk composition (EBC), that is, the bulk of the closed metamorphic system that stays in chemical equilibrium are crucial in deciphering the PT history of a metamorphic terrain. A variety of tools are used by metamorphic petrologists to calculate the effective bulk of a sample, such as XRF bulk data, average bulk using point count analysis,...
