Coal is formed from prehistoric plants buried much closer to the surface, and is unlikely to migrate below 3.2 kilometers (2.0 mi) through geological processes. Most diamonds that have been dated are older than the first land plants, and are therefore older than coal. Diamonds used in industrial processes are almost always lab-created diamonds.
It can be found in serpentine soils and south-facing slopes, which are generally inhospitable to most plants, as well as in slate, sand, clay, and gravel soils. Chaparral habitats are known for their fierce periodical wildfires , and like other chaparral flora, chamise dries out, burns, and recovers quickly to thrive once again.
Slate was freed from the rockface by blasting in shot holes hammered (and later drilled) into the rock. Slate mines were usually worked in chambers which followed the slate vein, connected via a series of horizontal "Floors" (or "Levels"). The chambers varied in size between mines and were divided by "pillars" or walls which supported the roof.
