印尼西苏门答腊Muara Sipongi附近的矽卡岩金矿化 Muara Sipongi位于印尼巴里桑山脉内苏门答腊西海岸,第二次世界大战前在此地开采过黄金,开发的二迭一三迭系的地层受苏门答腊下部印度板块活动的影响,苏门达腊右旋的横推断层平行于该地带的轴部,该断层域是苏门达腊下部印度洋壳板块倾斜下降的结果,其开发主要在NW—SE的断层带间,出露在巴里桑山脉的前第三系的岩石可分成三组,第一序列是在大陆边缘的石炭纪一早二迭世的沉积,第二序列是分布在东部的滨海相的砾砂石
Skarn gold mineralization near Muara Sipongi, West Sumatra, Indonesia Muara Sipongi is located on the west coast of Sumatra, in the Barryang Mountains of Indonesia, where gold was mined before the Second World War. The stratigraphic layers of the Triassic Triassic developed by the Sumatra Lower India Plate tectonic movement, the Sumatra diagonal thrusting parallel to the axis of the zone is the result of a dip-dip in the lower Indian Ocean plate of the Sumatra, which is mainly developed in NW-SE fault zones , The Tertiary rocks exposed in the Barisan Mountains can be divided into three groups. The first sequence is the deposition of Carboniferous-Early Permian on the margin of the continental margin. The second sequence is the gravel sand distributed in the eastern coastal facies stone
