Oct 19, 2023 · Oil shale can be thought of as a precursor to oil and natural gas. With more pressure and over more geological time, kerogen would heat to its “oil window” or “ gas window ” (the temperature at which it would release crude oil or natural gas).

Shale gas – Natural gas trapped in shale formations; Whe Bedding Planes. Figure 5.4.1 5.4. 1: Horizontal strata in southern Utah. The most basic sedimentary structure is bedding planes, the planes that separate the layers or strata in sedimentary and some volcanic rocks. Visible in exposed outcroppings, each bedding plane indicates a change in sediment deposition conditions.The Burgess Shale is a fossil -bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. [2] [3] It is famous for the exceptional preservation of the soft parts of its fossils.
