摘要
在青白口纪之前,扬子板块与华北板块之间为古中国洋相隔,经过漫长的汇集,最终完成拼合,其间三大地块相互作用,形成一套中浅变质沉积火山岩系——武当岩群。其形成过程经历了碎屑岩沉积、双峰山火山喷发沉积和变形变质改造三大阶段。
Yangtze plate and North China plates were separated by the ancient Chinese ocean before Nanhuan Period.In the long collection interaction between the three plots formed a set of shallow metamorphic sedimentary volcanic rocks-Wudang rock group in the final completion.Its formation process experienced clastic sediments,twin mountain volcanic eruptive sediment and metamorphic transformation of three phase distortion.
