摘要
湘赣边地区构造岩浆带是环太平洋成矿带内最重要的高值地质矿产异常区，其中ＮＮＥ向走滑断裂明显地控制了岩浆－断陷盆地和铀及钨、锡、铅、锌、锑等的成矿作用．在区域地质环境研究的基础上，根据典型矿田（床）控矿构造分析成果，将走滑断裂带内局部性致矿地质异常归纳为：帚尾式致矿异常，棋盘格式致矿异常、辫状结环式致矿异常和拉分盆缘式致矿异常．重点讨论了各类异常的结构样式和分维特点．
The tectonomagmatic belt between eastern Hunan and western Jiangxi is a significant geological anomaly area in circum-Pacific metallogenic belt, in which NNE-trending strike-slip faults directly controlled magmatism-fault basin-mineralizing process of U, W, Sn, Pb, Zn, Sb, etc.. Based on detailed study of regional metallogenic settings and ore-controlling structural analysis of typical orefield and deposits, the local ore-forming geological anomalies in the strike-slip fault zone are concluded as ①brush-tail type, ②chess-board type, ③braided lozenge link type and ④pull-apart basin type. The structural patterns and fractal dimension of each geological anomaly are discussed.
