摘要
广西佛子冲铅锌矿田构造受博白—岑溪断裂带控制，早期形成的ＮＥ向构造以挤压为主，稍晚的ＮＮＥ向构造以水平剪切为主，兼具挤压特征。矿田成矿与地洼晚期的引张应力场有关。文章通过岩石组构、有限应变测量和节理的综合分析，厘定了多期、复杂的矿田构造发展史。
The author analyses and expounds the horisons in which the conglomeratic rock in lower-mid triassic series lies and their features. He divides this rock into three genetic types( watercourse conglomerate, collapse-sliping collapse conglomerate and sedimentary melange) and discusses their forming environment and its significance. Finally, he points out that they all were the sedimentary performance of the structural affection during triassic period.
