== == == == == == 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 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.
Shale rock can be grayish in colour and has a white marble effect on the top
Because all the minerals piled on top of it and pressed down on it so they all squish on top on it
the creek dried up and made shale, then what could of happened is it made a layer of shale and later limestone formed and made a layer of limestone on top of shale

I think it is because animals died then mud piled on top the another layer of animals and so on.
Top coal producers in 2006 were: China USA India Australia South Africa
It is found underneath the ground. It is found in the United states in the Appalachian Mountains from Alabama through Pennsylvania. It is found in Wyoming. It is found in China, India, Australia, Europe, Russia, South Africa, and other places. This is minddrag recommend me. The answer is: Proven coal deposits exist on every continent, including Antarctica. The United States has the world's largest supply of recoverable reserves, or about 24 percent. Coal is found in thirty-eight states, and nearly one-eighth of the country lies over coal beds. Top coal-mining states include Montana, Illinois, Wyoming, West Virginia, Kentucky, Pennsylvania, Ohio, Colorado, Texas, and Indiana.
China is at the top of coal producers.Other important countries are USA, India, Australia and Russia.

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.

The United States produces about 20% of the world's supply of coal. Montana is the state with the most coal reserves, but Wyoming is the top coal-producing state. Coal generates about half of the electricity used in the United States.
Coal may be mined in underground mines, typically by machinery that pulls the coal from the seams, and transports it to the surface. Coal is also mined in surface mines by removing the soil and rock on top of the coal, and then using machinery to break the coal from the seams, and move it to storage.
because it for used for mining

Typical of most part of Eastern Nigerian, Nanka Formation consiting of reddish clay-sand mix outcrops in most part of Nawfijah. Awgu Shale lies on top of Ajalli Sandstone for most part of the town. Rich aquiferous formation of Ajalli sandstone are found from about 25 meters to about 275 meters. Young metamorpic rocks (sandsones) are found mixed with latterite in vadose zones and root layers of the town. There are no outcrops of granite base rock anywwhere in the town. Awgu Shale have been found to reach up to 300 meters thick in nearby Ufuma but such Shale thickness are not know for Nawfija.
