风暴岩的野外识别方法

Study on the Field Identifying Method of Tempestite

风暴岩的形成有很大的偶然性,研究它具有重要的科学意义,作为地质遗迹,又有一定的观赏价值。选择湖北省鄂东南黄石大冶和鄂西北房县,相对较老地层寒武系和相对较新地层三叠系中两处较典型的风暴岩,阐述其形成环境、形成机理、岩石特征及野外识别方法。

There exists great contingency in the formation of tempestite. As a geological vestige, it has certain ornamental value, so the research on tempestite is of vital scientific significance. Two typical tempestites, in the Cambrian （relatively old stratum） and Triassic （comparatively new stratum）, are selected as subjects, which is formed in Daye, Huangshi of southeastern Hubei and Fangxian of northwestern Hubei. And their formative environment and mechanism, petrologic characteristics and field identifying method are discussed in the paper.
