| 摘 要： | 1976年的1∶20万勐腊幅、尚勇幅区调报告报导了景洪澜沧江边南光附近泥盆系的发现并将其时代确定为中—晚泥盆世.中泥盆统为海相沉积(未建组),上泥盆统为陆相沉积,并建“南光组”,对其地层层序及沉积环境和空间关系缺少深入研究.该剖面清楚地记录了复理石沉积建造与磨拉石沉积建造(由海到陆)的连续变化关系,沉积物以含陆源碎屑和火山碎屑物为特点,代表了该区中—晚泥盆世经历了与火山喷发活动有关的造山运动.这一发现将为研究澜沧江河谷地带的地质构造演化增加新的内涵.

| Abstract: | The Devonian's section in Nanguan area of Jinghong, southwestern Yunnan, which clearly showed continue transform from flysch to molasese dimentary formation.There are continental resource and volcanic clastics in the sediments, and it this area had been happened orogeny with volcanic eruption action during Middle-Late Devonian . The discover will provid some useful new evidence for understanding geotectonic evolution of southern Lancangjiang Valley. |
