period of time, but there is no evidence to suggest that this actually occurs. Volcanic activity does not directly lead to the formation of jadeite, as the high temperatures and pressures involved are not conducive to the formation of jadeite. Jadeite is mnly found in green schist metamorphic rocks, which are not commonly found in Hkou. It is true that certn minerals, such as olivine, may be found in volcanic areas, but these are not the same as jadeite. The formation of jadeite requires a long period of time and specific geological conditions, which are not typically found in volcanic areas.
