Do you have the strange rock of natural anaglyph? Feel how?

Xie Wu invites for nothing. Tell the truth problem advocate not oversensitive, problem advocate the description is not accurate, the Shi You that often gathers stone is clear, the stone of anaglyph grain actually very common, the anaglyph grain that just should get intended musical sound is very difficult, not common this ability is true. The formation of anaglyph grain is not complex, in same there should be two kinds of aboves only on rock of different color base cliff, and hardness is different, below the action that grinds to sand in water, softer base cliff is used up a bit faster, harder use up a bit slower, such anaglyph grain were formed, of course this is to show water develops stone. Of grain of hill stone relief sculpture forming is base two kinds of different material elements in cliff are acid-proof abhorrent ability forms alkaline degree. The stone of other is planted the formation of anaglyph grain also is very much the same, hope the answer can be satisfactory, thank.
