摘要:
南盘江盆地南缘发育大量早—中三叠世岩浆岩和巨厚三叠系，为研究沿中越边界一带是否发生洋盆俯冲消亡过程提供了重要的岩浆-沉积证据。选取中越边界地区出露面积最大的富宁—那坡地区早—中三叠世火山岩及相关沉积作为研究对象，通过系统的地质填图和剖面测量，查明这套火山-沉积组合具有下部玄武安山岩，上覆碳酸盐岩质砾岩、含砾粗砂岩和钙质砂岩的沉积序列，与岛弧环境火山-沉积序列相似。玄武安山岩SHRIMP锆石U-Pb定年结果为247±1 Ma和246±3 Ma，与野外产于中三叠统碎屑岩之下的地质事实相符。结合前人研究成果，确定这套火山岩形成于早—中三叠世（247~242 Ma）。全岩地球化学分析结果显示，玄武安山岩富集大离子亲石元素（LILEs，Rb、Th和U）和轻稀土元素（LREE），其具有明显的Nb、Ta和Ti负异常。火山-沉积序列和火山岩地球化学特征表明，富宁—那坡地区早—中三叠世火山-沉积组合形成于与俯冲相关的弧环境。中越边界地区早—中三叠世弧火山岩与蛇绿混杂岩带的时空展布特征表明，该地区晚古生代洋盆发生了向北的俯冲消减。
Abstract:The Late Paleozoic to Early Mesozoic tectonic evolution process along the Sino-Vietnam border, particularly the subduction polarity of the Late Paleozoic ocean basin, is still controversial.Massive Early—Middle Triassic magmatic rocks and thick Triassic siliciclastic system occurred in the south margin of Nanpanjiang Basin provide important magmatic and sedimentary evidences for settling dispute.The Funing-Napo Triassic volcanic rocks, as the largest magmatic outcrop, are the ideal object for studying the tectonic evolution along the Sino-Vietnam border.The systematic profile survey and geological mapping indicates that the volcanic-sedimentary succession that consists of lower basaltic andesites overlain by carbonate conglomerates, pebbly sandstones and calcareous sandstones, which is similar to the volcanic-sedimentary sequence in island arc setting.Zircon SHRIMP U-Pb dating results of basaltic andesites are 247±1 Ma and 246±3 Ma, which are consist with field occurrence that basaltic andesite is overlain by Middle Triassic clastic rocsk.Combined with previous results, it is determined that the volcanic rocks were formed at 247~242 Ma.The geochemical analysis shows that basaltic andesites are enriched in LILEs (Rb, Th and U) and LREE, with a remarkable negative Nb-Ta and Ti anomalies.Both the geochemical characteristics of basaltic andesites and the volcanic-sedimentary sequence suggest that the Early—Middle Triassic volcanic-sedimentary succession was formed in a subduction-related arc setting.The spatial and temporal distribution characteristics of Early-Middle Triassic volcanic arc and ophiolitic mélange, implies that a north-dipping subduction occurred along Sino-Vietnam border.
