摘要
论述了山柞旬地区泥盆纪各时期沉积相特征和古地理演化格局 ,认为当时并没有形成一个完整统一的沉积盆地 ,而是被古陆分隔但具有密切联系的几个裂陷盆地 ,其自南而北依次为安康古陆→旬阳 -镇安盆地→小磨岭古陆→柞山盆地。
The authors dissertate systematically the Devonian sedimentary facies and evolution frameworks of paleo-geography and conclude that not a unitive sedimentary basin but several related rifted basins separated by paleo-continents during Devonian Period, there appeared from south to north the Ankang paleo-continent, Xunyang-Zhengan basin, Xiaomaoling paleo- continent and Zuosui-shanyang basin, respectively.
