红旗岭-茶尖岭矿带铜镍成矿及陆壳条件

摘要

Hongqiling-Chajianling ore belt copper nickel sulifde deposit belongs to magmatic intrusion mineralization and metallogenic material copper, nickel and sulfur was derived from the mantle. The mineralization of copper nickel sulifde deposit is related to the melting of the mantle derived from the upwelling of the mantle after the continental collision, Mineralization dominated by deep liquation-penetration mode. Copper nickel sulifde mineralization and ore key factors:(1) the Huifa River stone ring fracture quickly import; (2) the shallow brittle ductile fracture development; (3) the mantle source magma continued, adequate supply. For copper nickel sulfide mineralization: the initial continental crust that transformed into the mature continental crust is necessary; transitional continental crust and mature continental crust is not conducive to the formation of copper nickel sulifde.%红旗岭—茶尖岭矿带铜镍硫化物矿床属于岩浆侵入体成矿，成矿物质铜、镍及硫均源于地幔。矿带铜镍硫化物矿床的成矿与陆壳碰撞后软流圈上涌导致的交代岩石圈地幔部分熔融有关，成矿以深部熔离—贯入方式为主。铜镍硫化物成矿及成大矿的关键因素：（1）辉发河超岩石圈断裂的快速导入；（2）浅部脆韧性裂隙的发育；（3）地幔源区岩浆的持续、充足的补给。对于铜镍硫化物的成矿：向成熟陆壳转化的初始成熟陆壳是必要的；过渡型陆壳及成熟陆壳均不利于铜镍硫化物的成矿。
