Copper and nickel mineralization of Gaobangshan intermediate to basic rock in north Guangxi

Gaobangshan intermediate to basic rock was formed by structure and magma activities of Sibao movement,which is the largest basic rock occurring in North Guangxi region with an area over 20 km2.Researches on the characteristics of rock phase,geochemistry,REE composition show that comparing with the stratiform or stratiform like basic ore comlex,they are all origin in the magma of the same source but the Gaobangshan rock body possesses better plutonic magmatic differentiation and ore forming geological conditions.It is believed that the bottom of the rock and magma passage at lower part and the nearby fractures are all important ore forming locations.Mineralized super-basic rock controlled by fracture in the rock body has been found for the first time.It is meaningful for prospecting copper and nickel deposit in North Guangxi.
