旋卷构造是一种常见的和独特的构造型式,但并未得到应有的重视。笔者有机会去法国作短期考察,在阅读文献过程中,发现法兰西大部和西班牙西北部总体构造格局,与帚状构造一般形态相符。由于考察不是针对旋卷构造而安排的,看到的实际现象有限。现据有关材料和实际所见,对法兰西帚状构造要点,作简要报道。法兰西帚状构造展布范围,包括法国的阿莫尼干和中央高地,西班牙西北部的伊伯雷及上述地带环绕的大西洋海域。旋回带的收敛段在阿莫尼干,撒开段在中央高地,整体上呈现向西收敛、向东撒开,并向东北微凸的帚状形态。阿莫尼干地区发育着右行剪切的透入性构造,其中又集中形成三个右行韧性剪切带,同样显示
Spinning construction is a common and unique type of construction, but did not get the attention it deserved. The author had the opportunity to go to France for a short investigation. During the process of reading the literature, he found the general structure of most of France and the northwestern part of Spain, which is consistent with the general shape of the broom structure. Due to the fact that the inspection is not arranged for the convoluted structure, the actual phenomenon seen is limited. According to the relevant materials and actual observations, briefings on the main points of the French broom structure are made. French broom structure distribution range, including the French Armonage and the Central Highlands, the northwestern part of Spain, Iberian and the above sea surrounded by the Atlantic waters. The convergent section of the swirling belt is in the dry of the Armoni. The spreading section is in the central highland, showing as a whole the convergence to the west, spreading eastwards and spreading to the northeast slightly convex broomform. In the Armoni region, there is an intrusive structure of right-lateral shearing, in which three right-ductile shear bands are also concentrated to form the same
