摘要

Through detailed research work, the authors discovered that this kind of rock can be divided into two kinds： one is terrigenous clastic rock, which is a kind of normal sedimentary rock,i.e., carbonaceous sandy slate, having no direct relationship with mineralization, whereas the other is exhalative rock formed by submarine exhalation—ferro-siliceous rock. It is thus inferred that the Deerni large-size Co-Cu deposit was mainly formed by submarine exhalative-sedimentation and was later enriched by superimposition of multi-stage mineralization. This discovery has important theoretical and guiding significance in search for such ore deposits in Deerni area.
