南秦岭沉积岩型金矿成矿潜力与找矿前景分析

METALLOGENIC POTENTIALITIES AND FOREGROUND OF PROSPECTING ORE FOR SEDIMENTARY ROCK-HOST GOLD DEPOSITS IN SOUTH QINLING

南秦岭沉积岩区广泛分布于商丹缝合带与勉略缝合带间的秦岭地块中，并以上古生界泥盆系最为发育。该含矿与岩矿建造中产出多种类型的浸染状金矿床，具有一定的空间分布规律。本文根据各金矿类型地质特征、岩矿与含矿岩系组成、所在区地质背景等方面，分析了它们的成矿潜力和找矿前景。

South Qinling sedimentary petrologic province is widely distribute in Qinling massif between Shangdan and Mianlie stylolitic structure, upper Paleozoic group Devonian system in which is most developmental. Those types of disseminated gold deposits havebeen formed in the ore-bearing and ore-host formation, and have some regularly in space distribution. Based on geological features of these gold deposits, components of ore--bearingformation, and regional geological setting, analysed the author this paper their metallogenicpotentialities and foreground of prospecting ore.
