以实际资料为基础，通过对角砾化白云岩基本特征的论述及形成条件的分析，提出了其动力学成因既不是重力滑塌也不是断层破碎，而是高孔隙岩层内异常流体高压所导致的水压破裂作用这一新认识；区内中一下寒武统清虚洞组和熬溪组中的角砾化白云岩，岩性独特，层序稳定，以大量方解石贯入胶结为标志，是湘黔边境著名汞矿带的主要含矿层。
Based on the actual data, through the discussion of the basic characteristics of diagonal gravel dolomite and the analysis of formation conditions, it is proposed that the dynamical genesis is not caused by either gravitational or fault fracture, but due to the abnormal fluid pressure in the high-porosity rock formation Of the new understanding of hydraulic fracturing in the area; some Cambrian Qingxudong Formation and the boil Creek Formation in the brecciated dolomite, unique lithology, sequence stability, with a large number of calcite penetration cement as a sign of Xiang Qian border famous mercury belt main ore-bearing layer.
