| 摘 要： | 挠曲褶皱构造在山西广泛存在,大同市之西盆地边缘"口泉山断裂带"实际是一个大型挠褶构造带。以往的研究者仅把它当成几个断裂分段研究。认识和研究挠褶构造不仅能够在理论上取得进展,而且还能够指导煤矿勘探和开采,取得很好的经济效益。通过构造带上几个地方典型构造现象的研究得出,该构造带构造现象虽然复杂,但它并不是杂乱无章的,运用挠褶构造的理论上能够恢复它的原始形态以及它的发生发展的全过程。挠褶构造的形成与构造块体的隆升有关,其形成为:地幔柱隆升-地层上拱-挠褶-冲断走滑等。

| Abstract: | flexural folds exist extensively in Shanxi Province.Kouquanshan fault belt is a real large type flexural fold belt.Study on it can provide a guide for the exploration of the coal mine in the area.Based on the typical structural phenomena and the theory of the flexural fold,the original form and its developing process can be restored.The formation of the flexural folds is related with the uplift of this structural body.The process is proposed as the plume rising-strata rising-flexural fold-thrust-strike-slip fault. |
