【摘要】 青藏高原东部三角形的松潘-甘孜褶皱区,全区几乎被巨厚的三叠系浊流沉积覆盖,掩盖了许多地质信息,成为国内一块神秘的土地。由于地质构造特殊性,造成了许多地质问题的多解性和专家认识的不确定性,许志琴(1991)称此区“为中国地质百慕大”。从古板块演化“、峨眉地幔柱”“、峨眉地裂运动”和沉积盆地学等方面探讨该问题,试图揭开该区地质上的神秘面纱,并提出国内地学界最感兴趣的几个基础地质问题。更多还原

【Abstract】 The triangular Songpan-Ganzi folded area in eastern Qinghai-Tibetan plateau is almost covered with very thick Triassic turbidite deposit and lots of geologic information may be enveloped,so it becomes a mysterious land in China.Its particularity of geologic structure,multi-explanation of most geologic problems and uncertainty of domestic experts’ recognitions allowed this area to be even called "Chinese Geological Bermuda"(after Xu Zhi-qin,1991).This paper discussed this problem in detail in aspects of old plate tectonic evolution,"Emei mantle plume","Emei taphrogeny" and sedimentary basin evolution,etc.,trying to uncover the mysterious geological veil.In addition,this paper puts forward several fundamental issues to be discussed that are most interested in nowadays in domestic geosciences field.更多还原
