How does slate and sandstone distinguish?
Sandstone is formed from quartz particles (sand), structurally stable, usually light brown or red, mainly silicon, calcium, clay and iron oxide
The color of the slate varies with the impurities it contains.
Rock is a plate-like structure, basically no recrystallization of the rock, is a metamorphic rock, the original rock is muddy, silty or neutral tuff, along the plate direction can be stripped into thin slices
Slate is a layer containing sericite, relatively smooth, sandstone is granulate stone rough.
