补充资料:底辟构造
底辟构造 diapiric structure 密度较小的高塑性低粘度的岩石(如岩盐、石膏或泥岩等)向上流动,拱起甚至刺穿上覆岩层所形成的穹隆或蘑菇状构造。简称底辟。底辟的直径可从几米到几千米。盐丘是最常见的底辟构造,它由盐类岩石或石膏向上流动或挤入而使上覆岩层拱曲隆起所成。核部的盐体常成圆柱状,其内盐层变形复杂。盐核之上的上覆岩层往往形成穹隆或短轴背斜及伴生的放射状或环状断层。盐核周边与围岩常为陡倾的断层接触,围岩倾角也变陡。盐丘周围的岩层因盐丘上隆而相对下坳,形成周缘向斜,盐丘构造具有重要的经济价值,盐核常成重要的盐类或硫磺矿床,盐上的穹隆及周缘围岩中常富集石油和天然气。 以泥质为核的底辟称为泥质底辟,又称泥火山,泥质中的甲烷气体在泥火山形成中起了重要作用。由岩浆上拱并侵入围岩而形成的称岩浆底辟。 |
