| 摘 要： | 在白云鄂博区北面的比鲁特附近,出露一条超基性岩。超基性岩露头长度约1200米。宽度沿走向有明显的变化,从几米到30米。过去,这个超基性岩露头被认为是侵入的岩体,并定为加里东期侵入体1)。近几年,还有人认为它是一个金伯利岩岩体。 我们在研究白云鄂博群的岩石学工作中,发现该超基性岩,至少露头部分是经受了沉积作用改造的滑塌堆积。本文对这一滑塌堆积作一简要报道。

| Abstract: | The Bilute serpentinite found north of Bayanobo was earlier considered as an ultrabasic intrusive body or a kimberlite pipe.Recently,having observed the inner structure of the serpentinitie piles and the sedimentary structure of underlying and overlying sedimentary rocks,the authors suggest that the serpentinitic rocks can be ascribed to a kind of olistostrome formed due to submarine slump.It is quite evident that the existence of olistostrome can be used to explain the sedimentation and tectonic-environments as it was generating. |
