... maturity. In the current study, the data obtained from Rock-Eval pyrolysis has been used to define the source-rock quality, generative potential, kerogen type, maturity of the source sediments and kerogen kinetics of the BaisakhiBhadesar Formation of Kimmeridgian–Tithonian (154.7–145.6 Ma) age. Basinal...
