| 摘 要： | 湖村盆地位于闽西宁化县境内，是闽西北地区变质岩系之上，几个零星出露上古生界的和下三叠统地区之一。本文运用平衡剖面的基本原理及构造解析方法，论证了湖村盆地既不是闽西北隆起之上的断陷盆地，也不是简单的“构造窗”而是在早三叠世末－中株罗世，闽西地区自北西向南发生叠瓦式逆冲推覆作用而形成的残存构造盆地。

| Abstract: | Located in Ninghua county of Fujian province, the Hucun structural basin is one of the several areas where there crop out Upper Paleozoic and Lower Triassic strata on older metamorphic rocks in northwestern Fujian. Based on the principles of the balanced cross-section and the methods of structure analysis, this paper discusses'the structure style of this basin and comes to the following conclusions; the Hucun structural basin is neither a fault basin on the so-called Northwest Fujian uplift nor a structure window but a remained structural basin formed during southeast-directed imbricate thrusting which occurred from the late Early Triassic to Middle Jurassic in this area. Besides, on the basis of the above study combined with geological data from the adjacent areas, the authors propose a preliminary tectonic model to explain the South China Mesozoic erogenic belt. |
