Compared to the area of the small region Wocan-2, there was observed the death of the stack height of about 1-3m 5 and a low temperature diffusion at a flow orifice, and a sulfide, Fe-Mn crusts and hydrothermal deposits and other areas .
In comparison, the Wocan-2 area is small, with five dead chimneys and 1 cryogenic dispersal perforation hole of about 1-3m in height, as well as sulphides, Fe-Mn crusts and hydrothermal sediments observed in the area.
