摘要
文中概括了秦岭造山带强烈变形区泥盆纪的同沉积期构造标志,总结了它们对成矿盆地和热液通道形成的重要性及其特征,论述了两类矿化与两类盆地—通道类型的成因联系。指出这些以沉积岩为主岩的沉积—喷气矿床,形成于扬子陆块北缘显生宙被动大陆演化的特定阶段,产于外陆棚海的三、四级盆(洼)地中。
The syndepositional tectonics is more important than some other factors controlled to sedimentary-exhalative ore deposits.Inthis paper there are syndepositional tectonic marks,the importance and features of them both for formation of minerogenic basinsand for supply of hydrothermal channels as well as genetic relationship between two type basins and two type channels.In consideration of other geological and geochemical data,it is suggested that these sediment-hosted exhalation ore deposits have beenformed at a non-orogenic tectnoic event during phancrozoic evolution of Yanzi passive continental margin and in 2 or 3-grademinerogenic basins (depressions) of the outer sheif sea basin.
