What is found on top of coal slate or shale?
== == == == == == The cap rock on a coal bed is usually a sedimentary rock, (i.e. shale sandstone etc.) but not always shale. Slate is a metamorphic rock, usually derived from shale that has been exposed to high pressures and temperatures over very long periods of time. Ways to tell the difference between slate and shale: Slate will have a smooth surface, and possible have light glare at a right angle. Shale will have a dull, sandy surface. Tap them against something hard. Slate will make a "clink" noise, almost like porcelain or ceramic, where shale will make a "thud" sound. Rub it against your teeth. Slate will be smooth, shale will be gritty. == == == ==
