平面上呈环状、等轴状或与之相近形态的构造,随着航天、遥感技术的实施,地球物理方法的广泛运用,大陆地质(特别是前寒武纪地质)、地震地质及火山地质工作的深入开展,在地球上发现得越来越多,研究也越来越深入,引起了人们极大的兴趣。 早在1904年A.M.Harker在苏格兰开展了对环状和圆锥状侵入体的研究工作,继之,E.M.Anderson(1924)用数学分析说明了这类独特侵入体的形成机理,绘制了苏格兰锥状岩蓆和环状岩墙形成的应力网络图。 我国卓越的地质学家李四光教授早就对环状和近等轴状的构造给予了充分的注意。1929年他提出了“旋卷构造”的论据,1957年发表了“莲花状构造”一
Its structure is circular, equiaxed or similar in plane. With the implementation of aerospace and remote sensing technologies, the extensive application of geophysical methods, continental geology (especially Precambrian geology), seismic geology and volcanic geology The work carried out in depth, more and more discovered on Earth, more and more in-depth research has aroused great interest. As early as 1904, AMHarker conducted a research work on ring and cone intrusions in Scotland. Subsequently, EMAnderson (1924) mathematically analyzed the formation mechanism of this unique intrusive body and plotted the Scottish cone The stress network formed by the mat and ring dykes. Professor Li Siguang, a distinguished geologist in our country, has paid sufficient attention to the structure of circular and nearly equiaxed structures. In 1929 he put forward the “convolute structure” argument, published in 1957, “Lotus-like structure,” a
