摘　　要：本文根据国内外许多矿床中海底喷气角砾岩的空间分布、物质成分及组构等方面的资料,总结了它们的基本特征和形成机制,划分出4种亚类。还指出研究这类角砾岩对判断同沉积断裂,分析区域地质、构造演化、勘查及预测喷气型金属矿床均具有重要意义。Submarine eruption braccia belongs to a new genetic type of braccia.Its essential features and for-ming mechanism are summed up in this paper on the basis of its spacial distribution,compositions andfabric observed in some mineral deposits at home and abroad.Such braccia may be subdivided into foursubtypes and they are of great significance in judging supratenuous fractures,analysing regional geostruc-tural evolution,and prospecting and prognosticating ore-deposits of eruption type.
