== == == == == == 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.

Shale for road building?
Shale in general is the most abundant of stratified rocks. One of the most popular forms of shale used for building roads is called Marcellus Shale. When this clay shale is nearly pure it is known as argillaceous. When it contains a lot of sand it is arenaceous. You will find that shale varies in color, reddish, very black, or grey. Shale is used mainly for top dressing on roads. To have a good road base slate is recommended.

Can you install laminate over rough slate?
I would definitely recommend against this. While laminate can be installed on top of tile, it requires that the floor is level and even. So, if your slate is rough and uneven, it is not a good subfloor to install any hard surface. If you install the laminate directly on top of an uneven floor like this, it will most likely crack and move a lot when you are walking on it. However, an alternative (albeit an expensive one), is to add self leveling cement on top of the slate and level out the floor, and then you could install the laminate on top. This might be less expensive and less difficult vs. trying to remove the slate, but it is not a cheap option.
