Shale is a fine-grained, clastic sedimentary rock, formed from mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by its tendency to split into thin layers less than one centimeter in thickness.This property is called fissility. Shale is the most common sedimentary rock.READ MORE
· Second, what if an actual fire could bake the right kind of sandy shale? In fact, that does happen in coal country. Forest fires can start coal beds burning, and once started these coal-seam fires may go on for centuries.
