【摘要】 1979年吴乃元、王明倩建立了和布克河组,当时定其时代为早石炭世早期。1982年吴乃元将该组时代改为晚泥盆世晚期。笔者研究了和布克河组的珊瑚化石,认为其时代属早石炭世杜内期早期。建立了1个珊瑚组合带,包括4属8种有:Caninia tregaensis-Kassinella xinjiangensis组合带,包括:Amp-lexus coralloides Sowerby,A.hobokensi sp.nov.,Caninia tregaensis Poty,Kassinella xinjiangensis sp.nov.,Siphonophyllia karamayensis sp.nov.,S.hobokensis sp.nov.,Circellia xinjiangensis sp.nov.,C.minor sp.nov.更多还原

【Abstract】 The tetracorals described in the paper were collected in 1983, from the HobokRiver Formation in Western Junggar, Xinjiang. They include 4 genera and 8 speci-es, forming an assemblage zone——the Caninia tregaensis-kassinella xinjiangensisassemblage zone. The elements are as follows: Amplexus coralloides Sowerby, A.hobokensis sp. nov., Caninia tregaensis Poty, Kassinella xinjiangensis sp. nov., Sipho-nophyllia karamayensis sp. nov., S. hobokensis sp. nov. and Circellia xinjiangensis sp.nov. Caninia tregaen, is Poty, Kassinella Keller and CirceIlia Ye et Wang are mainlyof early Tournaisian age. Thus the Hobokhe Formation yielding the above-mentio-ned tetracorals is roughly equivalent to the early Tournaisiau Etroeungtian bed ofWestern Europe.更多还原
