“青藏高原热”的掀起 ,极大地提高了西藏境内基础地学的研究水平和认识程度 ,为正确把握西藏喷流型及其它类型矿产资源的战略地位奠定了良好的基础。在此基础上 ,通过对甲马、沙拉岗矿区的矿床学研究 ,笔者认为它们都受“盆、相、位”的严格控制 ,具有喷流沉积的一般特征 ,属sedex型矿床的范畴。但二者之间却又存在元素组分、矿物成分、结构构造等方面的明显差异。产生这种差异的根本原因在于其形成的大地构造背景和盆地性质不同。 The “heat up of the Qinghai-Tibet Plateau” has greatly raised the level of research and understanding of basic geosciences in Tibet and laid a good foundation for correctly grasping the strategic status of the spouting type and other types of mineral resources in Tibet. On this basis, through the study of ore deposits in Jiama and Shalagang mining areas, the authors believe that they are all strictly controlled by “basin, facies and position” and have the general characteristics of jet sedimentation, belonging to the category of sedex deposits. However, there are obvious differences between the two in terms of elemental composition, mineral composition and structure. The fundamental reason for this difference lies in the different tectonic setting and basin nature of its formation.
