Increase in pressure - pressure also increases during deep burial or subduction. Reaction with surrounding hot fluids and gases - crystallization of new minerals is enhanced by exchange of ions with nearby hot, magmatic fluids and gases. Nonfoliated rocks - mineral crystals are equant in shape. As a resource, slate is nonrenewable, but common. Man-made roofing tiles are a suitable substitute.
