∙ 9y agoBecause it contains marble....................I think?
a rock is made up of 2 or more minerals. a few minerals are granite, marble, limestone, slate, schist, feldspar, and about 4000 more
== == == == == == 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. == == == ==
There is no specific or universal chemical formula for slate, because slate is formed up of various amounts of varying types of rock such as:QuartzMuscoviteIlliteBiotiteChloriteHematitePyriteApatiteGraphiteKaolinMagnetiteTourmalineZirconFeldsparIn some locations, such as the mountains of Wales, slate also contains iron.Because of the range of diversity of which slate is formed from - there is no universally accurate formula for slate in general.
Slate varies in color, but gray is one of the more common colors. Graphite can easily be distinguished from slate by its color. Slate has a dull luster while graphite appears metallic.
Marble and slate
marble is better for chess pieces
Yes, Marble is formed from Limestone, but not Slate.
It depends on the marble and the slate, Vermont marble erodes faster than Maine slate, for example. Vermont marble is more often used in interior work. Maine slate is ideal for roofing.
Slate and Marble are metamorphic rocks. Slate's parent rock is shale and Marble's parent rock is limestone.
MARBLE: In the town of PORTSOY on the Moray Firth, Scotland. SLATE: In the village of BALLACHULISH in the county of Inverness, Scotland.
With all the research I have done, I am pretty sure that you can use slate cleaner on marble.
Stone.
Marble and slate are both used by humans in buildings. Marble is used to make a number of items such as flooring and countertops. Slate is used primarily for roofing shingles.
The degree of metamorphism. Phyllite is slate further metamorphosed.
There are not many retailers for slate fireplace, most give intruction how to assemble or they sale slate to be applied. One website that may be helpful with different style fireplaces and the websites that offer them is http://www.slate-stone.com/slate-fireplaces.html .
