【摘要】 在《巴采矿花岗斑岩中交代钠长岩及其演化特征》一文中,作者揭示了巴泉花岗斑岩未被全部破碎成角砾,指出了马泉角砾岩非爆破成因。按M.E.Mcallcem和D.L.Reynolds等人的观点,流体化作用是爆发角砾岩筒成因的主要因素。笔者经过周密的野外调查,通过构造和岩石的分析工作,认为巴泉“岩筒”不是爆发角砾岩筒,“岩筒”中的角砾是经受强烈钠交代作用后被构造作用破碎成的构造角砾岩。更多还原

【Abstract】 In the previous article, "The character of metasomatic albitete and its evolution of granitophyre in Ba Quan uranodeposit" notes that the granophyre does not all fragment into breccia in which give a hint of petrogensis of the breccia. According to the viewpoints(of D.L.Reynolds, 1954, and M. E. Mcacallum, 1985)which proves the fluidization processes to be the petrogensis of explosion breccia, after a thorough investigation and detailed structural examination and petrological analysis, this paper demonstrates that the Ba Quan’s breccia pipe is not explosionbreccia pipe, and the breccia is a structural breccia fragmented by structuralstresses after strong Na-metasomatism.更多还原
