The Yangla bedded Cu orebodies in Linong block occurred in volcanic—sedimentary rock series, which consist of various tectonic massif from Middle Devonian to Lower Permian and their genesis were concurrent. The REE characteristics of silicalite indicate that it has been formed in continental margin—bathyal environment. Host rocks of orebodies are mainly skarn riched in Fe, the occurrence of several orebodies are bedded and layeredlike paralleled with stratum,orebodies incline toward west and extend over 2 km. The orebodies do not contact Indosinian granodiorite directly and are different from contact metasomatism skarntype deposit. This study makes research on typical No. 2 and No. 5 orebodies and their wall rocks by petrology, mineralogy and REE geochemistry, the results show that the ores have syndepositional characteristics. Fe content in ore bearing skarn is far more than that skarn in normal contact metasomatism. It is inferred that skarnization has widely occurred in various rocks of volcanic—sedimentary rock series in Linong Formation and Jiangbian Formation, the primary syndepositional ore bed would provide Fe from pyrite and melnikovite. Positive correlation of δEu and Cu grade might indicate varying degrees of superposition and enrichment resulted from skarnization. The genesis of Linong bedded ore deposit can be concluded as follows: primary sulphide orebodies formed in Neoproterozoic as a result of submarine sedex Indosinian island arc granodiorite reformed and upgraded primary sulphide orebodies more or less and finally turned them into thick and high grade orebodies. Yangla bedded deposit is a compound origin deposit with stratabound characteristics.
