Question
The thermal maturity of this material can be quantified with the vitrinite reflectance and is plotted on van Krevelen diagrams. For 10 points each:
[10h] Name this insoluble organic component of sedimentary rock mostly composed of dead plants and marine microorganisms. Macerals of this material undergo partial decomposition to form fossil fuels.
ANSWER: kerogens [reject “bitumens”]
[10e] Kerogens are rich in the “oil” form of this sedimentary rock. Natural gas is extracted from the Barnett and Marcellus formations of this rock via fracking.
ANSWER: shale [accept oil shale or shale gas]
[10m] Biopolymer-rich sediments condense and vulcanize to form kerogens and bitumens as part of this broad set of transformations that occur during the formation of sedimentary rocks. For kerogens, this process is followed by catagenesis and metagenesis.
ANSWER: diagenesis
