摘　　要：缅甸联邦实皆省MTT金铜矿床位于曼德勒以西约200km新生代安山岩中,属块状硫化物金铜矿床。对其成矿地质特征进行了研究,有助于在新生代安山岩中发现相同类型的矿床。矿体产在缅甸中部盆地地体之西缘,赋矿地层(即含矿岩系)为陆相安山岩,硫化物矿体呈层状、似层状和透镜体状。矿石具块状构造,矿石中主要成矿元素为Cu、Au、S;铜矿石品位较高,属富铜矿。该类型矿床的找矿标志是:具有低阻高极化的物探异常。MTT Au-Cu deposit was a kind of massive sulfide deposit and located in Tertiary andesite about 200km away from the west of Mandalay, Union of Burma. The author studied its metallogenic geologic characteristics, which would help to discover the deposit of the same type in Cenozoic andesite. The ore body was situated at the west edge of central basin terrane in Burma. Ore-hosting strata and ore-bearing rocks were continental andesite. Sulfide ore bodies were stratified, stratiform-like and lenticular, and of massive struc- ture. The primary metallogenic elements were mainly Cu, Au and S. The ore was rich with copper, and the grade of Cu was very high. Low resistance and high polarization geophysical anomaly were the prospecting indicators for this type of deposit.
