   Hydrocarbon Systems
   Shale plays a dual role in petroleum geology: as a source rock and as a seal. When subjected to sufficient heat and pressure (the "oil window" [oil window]), organic matter within the shale kerogen matures into oil and natural gas.

   Argillite: A low-grade metamorphic rock derived from shale or mudstone, characterized by slight hardening due to incipient metamorphism (diagenesis beyond typical shale formation but below slate).
   Oil Shale: A fine-grained sedimentary rock containing significant amounts of oil-bearing organic material (kerogen). The [energy](/ent…
