Evolution-motion of crustobodies and geotectonic metallogeny

Following the paper entitled A Preliminary Proposal on Crustobody Geotecton ics presented by the first author to the 30th IGC in 1996, this paper furth er extends and elucidates the concept of crustobody in order to make a unif ying study of the evolution and motion of crustal structures and to underst and the law governing the formation and development of the earth' crust. In this paper the characteristics of crustobody evolution-motion are given. T he authors lay emphasis on the relationship between crustobody evolution-mo tion and tectonic metallogeny. In the end, a multiple dynamic system of the crustobody evolution-motion is discussed from internal and external dynami c forces, and the mantle creep in internal dynamic factors is paid special attention to.
