Macerals found in kerogen source rocks are often observed under the microscope to determine the kerogen maturity of the sedimentary formations.

23.
This polymerization usually happens alongside the formation of a mineral component ( geopolymer ) resulting in a sedimentary rock like kerogen shale.
24.
Type III kerogen involving rocks are found to be the least productive upon pyrolysis and probably the least favorable deposits for oil generation
25.
Below this zone, heated gas caused retorting process converting kerogen in oil shale to oil shale gas and shale oil vapors.
26.
The Cenozoic deposits have gas-prone Type III and II kerogen, with up to 2.5 % TOC locally.
27.
The kerogen that is found in association with the gold deposits almost certainly represents what remains of these Archean photosynthesizing micro-organisms.
28.
The kerogen in oil shale can be converted to shale oil through the chemical processes of pyrolysis, hydrogenation, or thermal dissolution.
29.
Different types of kerogen reflecting different initial conditions mature ( i . e . volatilize ) at different temperatures and pressures.
30.
Anhydrous incubation experiments have shown that the products are generally more depleted in D than their precursors, causing enrichment in residual kerogen.
