Shale Rock: Geology, Composition, Uses

Aug 02, 2020  Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color. Shale is commercially important. It is used to make brick, pottery, tile, and Portland cement.

Shale gas: more or less polluting than coal Carbon Brief

If NOAA is right, then shale gas could be more polluting than coal. But there is now other research out there that disagrees – for example a peer-reviewed study part-funded by ExxonMobil used a life cycle assessment of shale gas to conclude that the carbon footprint is shale gas is 53 per cent lower than coal.
