在法国南部的朗格多克晚侏罗世的微晶灰岩显示了清楚的张裂隙、缝合线和走向滑动断层。这些显微构造表明了一次主要构造期的特征:晚始新世比利牛斯近南北向挤压作用。一些继承性的地壳破裂,表现为区域性左旋断层,走向约北东20°～40°,又重新活动了。研究地区靠近科康涅-马特勒断层。在这个地方,张裂隙和缝合线格外地彼此斜交,有时垂直(图1 a)。为说明这种情况,一般给
Microcrystalline limestone in the Late Jurassic of Languedoc in southern France shows clear cracks, sutures and strike-slip faults. These microstructures indicate a major tectonic period characterized by near-north-north crustal compression of late Eocene Pyrenees. Some of the succession of crustal ruptures, manifested as a regional left-lateral fault, to the north about 20 ° ~ 40 °, reactivated. The study area is close to the Kokonie-Mataler fault. In this area, the cracks and seams are particularly oblique to each other, sometimes vertically (Figure 1a). To illustrate this situation, the general to
