Read MoreMost limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles. In many cases, the grains are microscopic fragments of fossil animal shells. Limestone has

If the shale is hard and difficult to remove, you can try soaking the fossil in water for a short period of time, about 5-15 minutes. This may help soften the shale and make it easier to remove.
Read MoreCommon sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks:

In current usage, unconventional oil and gas refer to, respectively, tight oil produced from oil-bearing mudstone, and shale gas produced from gas shale or associated with tight oil. As noted above, both require massive hydraulic fracturing.
Read More2023.10.19 Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons are substances made entirely of hydrogen and carbon. Petroleum and natural gas are probably the most familiar . hydrocarbons.The hydrocarbons in oil shale can be used as an

This new natural gas resource, extracted in more than 30 sedimentary basins across the continental USA and others worldwide, accounted for about 1% of gas production in the USA in 2000, 10% in 2011, and may

Read More2021.6.25 Shale oil and gas, as mentioned earlier, are the remnant hydrocarbons trapped in the source rock. Hydrocarbon expulsion from the source is initiated and facilitated by fractures, created in shales due to increasing pore pressure of oil and gas generated by breaking of kerogen during thermal maturity, a process known as catagenesis (Chapter
Read MoreFine-Grained Clastic Rocks. Rock composed of at least 75% silt- and clay-sized clasts is called mudrock (Figure 5.5, bottom row). If a mudrock shows evidence of fine layers (laminations) and breaks into sheets, it is called shale.Otherwise, it is siltstone (dominated by silt), mudstone (a mix of silt and clay), or claystone (dominated by clay). The fine
Read More2022.10.3 Shale is a fine-grained sedimentary rock that is formed when silt and clay are compressed. It is composed of many thin layers, and it readily splits into thin pieces where these layers meet—making it a relatively brittle stone. [2] Shale is composed of small grains and various minerals along with organic particles.
