| 摘 要： | 高邦山中基性岩体形成于四堡运动的构造岩浆活动,是桂北地区出露最大的基性岩体,出露面积20km^2以上.对该岩体的岩相、地球化学、稀土元素组成等特征的研究表明,其与区内层状、似层状成矿基性杂岩体相比,具有同源岩浆成因,并有着更好的深部岩浆分异作用和良好成矿地质条件.研究认为,该类岩体底部、下部的岩浆通道及附近断裂构造为重要的成矿场所.首次在岩体内发现受断裂控制的矿化超基性岩,这对桂北铜镍矿找矿有着重要的启示作用.

| Abstract: | 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 km^2. 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. |
