摘要
以秦岭造山带中热水沉积成矿盆地为例， 讨论了热水沉积成矿盆地的研究思路与方法（１）， 在这些盆地中已发现了一批大型－超大型矿床， 也是秦岭超大型矿集区的研究原理、研究及研究内容等基本准则。提出盆地充填史、盆地内同生构造作用等研究沉积盆地形成与发展。认为秦岭热水沉积成矿盆地具有分级特征， 热水沉积岩相是主要的物质组成。总结了秦岭中（火山）热水沉积成矿盆地、深水缺氧环境中热水沉积成矿盆地、叠合盆地、复合盆地、拉分盆地、裂陷盆地等六种构造－沉积岩相时间－空间组合模式， 它们是超大型金属矿床产出部位。
An Approach on sedimentary basins in the Qinling orogen(partⅠ) has been discussed in this paper As a series of large to superlarge metal deposits have been found recently in these basins, these basic principles can be employed to better understand the development and formation of basin in the area based on research of history of basin filling and analysis of the syntectonism in the basins The sedimentary basins with hydrothermal depositions in the area can be recognized four different subbasins, in which hydrothermal sedimentary rock facies are the major materials of basin fillings Time dimension patterns of tectonic sedimentary rock facies at the basins can be classified into the volcanic hydrothermal depositional basin, the hydrothermal sedimentary basin in deep water environment with oxygen poor, the compound sedimentary basin, the pull apart basin and the half garben baisn These basins are the space in which superlarge metal deposits occur
