“三江”地区哀牢山带两类硅质岩 特征及大地构造意义
Characteristics and Geotectonic Implications of Two Sorts of Silicalites in Ailao Mountain Belt, “Three_River” Area
摘要
Abstract
Late Devonian (D3) silicate and Early Carboniferous (C1) silicatein Ailao Mountain belt, “Three_River” area, are quite different from each other in mode of occurence, Radiolaria association, Si isotope and REE character. The former was formed in a deep_sea environment, i.e., in an intracontinental rift, whereas the latter is a component unit of Ailao Mountain ophiolite suite formed in a bathyal environment, indicating that Ailao Mountain was a small oceanic basin at that time.关键词
