| 摘 要： | 河池-宜州断裂带是一条东西向构造带,位于扬子地块东南缘雪峰山构造带南部,与扬子地块主体NE向的构造格局明显不同,其成因始终不明确。本文通过遥感构造解译、野外地质观察、构造剖面绘制、地震和MT剖面解释等手段,对河池-宜州断裂带东段进行了空间上由浅入深的系统研究,研究表明断裂带总体表现为向北逆冲的叠瓦构造分割了雪峰山南段构造体系和桂中坳陷构造体系;河池-宜州断裂带经历了多期次活动历史,其中现今构造格局主体由印支期和燕山期复合动力学机制下形成的,西段主要由印支期向南的弧形逆冲推覆阶段形成,东段主要由燕山期向西的弧形叠瓦式逆冲推覆奠定,它们的弧顶正好在宜州附近交接。

| Abstract: | The Hechi-Yizhou fault zone is an east-west structural belt in the southern Xuefeng Mountains of the Yangtze block. It is significantly different from the NE-trending tectonic framework in the Yangtze block. But the cause is not clear. Based on remote sensing image,abundant field data,geological structural sections,MT and seismic interpretation,this paper systematically analyzed the Hechi-Yizhou fault zone from the surface to the depth. This research shows that the structural pattern of the Hechi-Yizhou fau... |
