A Study on the Community Facies of the Late Carboniferous San Lixia Bioherm in Qinling Geosyncline, Shaanxi
陕西秦岭海槽晚石炭世三里峡生物礁群落相研究

This paper discusses in detail the growth process,palaeoecological features and the function of organisms in reef building of the San Lixia reef in Shaanxi. Organisms are relatively monotonous in the reef, 23 genera belonging to 6 phyla have been recognized.They consist mainly of Foraminifera , Algae, Brachiopoda and Ostracoda etc., and form 2 communities. Each community has its own salient ecological features. Analysis of all communities shows that the organic functions are very complex. There are different reef building actions at every reef building stage. The growth process of the reef may involve 3 stages: stabilization stage, baffle reef stage and bind cover reef stage.
