摘　　要：攀西裂谷是中国最重要的成矿带之一,其中钒钛磁铁矿主要集中在攀枝花、红格、太和、白马等四大矿区。中干沟为红格矿区的重要组成部分,本次研究将矿区内基性-超基性岩体视为同一大岩盆,受后期断层和正长岩的影响,被分割成了南西部、北东部和东部3个含矿岩体。含矿岩浆侵入期次分为4次小的脉动,其中第一次和最后一次脉动的规模最大,形成的矿体最好。按此认识指导勘探,在东部含矿岩体中有重大发现,西南主含矿岩体的资源量也有较大提升,新增资源量达到大型规模,矿区内及外围深部还有较大的找矿潜力。Pan（zhihua）-xi（chang） Rift is one of the most important metallogenic belts in China, and va- nadium titano-magnetite deposit is the most important representative which occurs mainly in the four min- ing districts, namely Panzhihua, Hongge, Taihe, Baima. Zhonggangou is an important part of Hongge mining district. This paper considers that the basic-ultrabasic rock bodies at Zhonggangou are of the same volcanic rock basin which was reworked by later faulting and cut into three ore-bearing bodies namely the southwest body（W）, the northeast body （N） and the east body （E）. Large ore-bearing magma intrusion occurred only once, but there were at least four pulses. The first and the last pulse were in large scale and ore bodies formed are large and in high quality. According to this engineering is laid out and a significant discovery made in the eastern body and resources in the southwest have greatly improved. The amount of increased reserves is considerable. To depth of the mining district and in its surroundings is still potential thus deepening of the ore-forming regularity study will guide further exploration in the area.
