| 摘 要： | The so-called“Yangtze-type”copper deposits include:（1）Cu-bearing massive pyrite bed ,(2)Cu-bearing skarn and magnetite-type ore deposits,with replacement Cu-vein-type deposits near the metasomatic zone,and (3)mineralized intrusive bodies and breccia pipes ,some of which are known as porphyry copper ores(e.g.Chengmenshan).This type of ore deposits is a typical example to verify the polygenesis of inost of the deposits in China,as has been promoted by Prof.Tu Guangchi in view of the polycyclic development of the geological history in China.This paper is con-cemed with one sub-type of such deposits.

| Abstract: | The so-called “Yangtze-type” copper deposits include: (1) Cu-bearing massive pyrite bed, (2) Cu-bearing skarn and magnetite-type
ore deposits, with replacement Cu-vein-type deposits near the metasomatic zone, and (3) mineralized intrusive bodies and breccia
pipes, some of which are known as porphyry copper ores (e. g. Chengmenshan). This type of ore deposits is a typical example
to verify the polygenesis of most of the deposits in China, as has been promoted by Prof. Tu Guangchi in view of the polycyclic
development of the geological history in China. This paper is concerned with one sub-type of such deposits. |
