苏格兰北部莫纳湖(Loch Monar)畔的莫茵岩系(Moine Series)中发育了复杂多姿的迭加褶皱构造。由于湖水的长期冲刷,形成了得天独厚的天然磨光面,露头之好是世人罕见的。更因露头而切割了不同方向的褶皱剖面,使露头型式绚丽多彩。对该区变质岩中迭加褶皱现象的认识将对变质岩区,尤其是变质条带状铁矿区的构造研究颇有启发。本文仅选择一些典型的迭加褶皱现象推荐给广大读者,现简叙如下: 莫纳湖畔的前寒武系的莫茵岩系主要为变质的砂质及泥质岩,以石英片岩及条带状变粒岩为主。由于泥质含量的不同,使有的条带富含暗色矿物(以黑云母为主)而呈深色;以长 In the Moine Series by Loch Monar in northern Scotland, complex and superimposed fold structures are developed. Due to the long-term erosion of the lake, the formation of a unique natural polished surface, good outcrops are rare in the world. But also because of outcrop and cut in different directions fold profile, so that outcrops gorgeous. Understanding of the superimposed folds in the metamorphic rocks in this area is quite enlightening on the study of the structure of the metamorphic rocks, especially the metamorphic striped iron ore zones. In this paper, only a few typical phenomena of superimposed folds are recommended to the readers. The following is a brief introduction: The Precambrian Mo Yan series along the banks of Lake Mona are mainly metamorphic sandy and argillaceous rocks. Quartz schists and bands Like granulite-based. Due to the different shale content, some bands are rich in dark-colored minerals (dominated by biotite) and dark in color.
