The present paper studies its metallogenic paleo structures, paleogeography, and rocks, ores, mineral compositions, trace elements, rare earth elements and Pb-isotope of ore-bearing, and compares it with some submarine exhalation-sedimentary Pb-Zn ore deposits in other countries.
通过对陕西银硐子沉积型银铅多金属矿床成矿的古构造、古地理环境以及矿床的含矿岩系的岩石、矿石、矿物成分、微量元素、稀土元素、铅同位素等地球化学特征的研究,并与国外某些海底喷气沉积铅锌矿床相比较,发现它们具有极为相似的地质、地球化学特征,表明该矿床是在正常海相沉积与海底喷气沉积相渗合而形成的,是具有较大经济价值的银铅铜锌贱金属-贵金属(特大型)综合矿
4) submarine volcanically exhalative-sedimentary origin
海底火山喷流-沉积成因
5) shallow sea volcano exhalation genesis
浅海火山喷气成因
6) submarine volcanic exhalation
海底火山喷气

Thus, it is determined that the bedded tourmaline belongs to volcanic exhalation-diagenic metamorphic origin, forming in the submarine volcanic exhalation-sedimentary tectonic setting, its primary rock is a set of the rich B-Mg argillaceous iron-silica rock.
描述了层状电气石岩的物理特征、岩性组合特征,分析了其化学成分,作了理论研究,确定了该层状电气石岩为火山喷气—沉积变质成因,形成于海底火山喷气—沉积构造环境中,其原岩是一套富硼镁的泥铁质—硅质岩石。
