根据矿床产出地质环境、双峰式火山岩系、沈积建造以及火山岩地球化学特征，推断昆仑式火山岩型块状硫化物铜矿床最可能形成于泥盆纪石炭纪弧后拉张构造环境。 - Due to the multi - period tectonic movement and evolution of mechanical mechanism , syndeposition structures occur extensively in jiyang sag , the base of the sag subsided alternatively during the fault depression , which resulted in sinking of top bending and complicated block structure accordingly , reconstructed the syndeposition intensively , and produced the special structural landscape in combination with all levels of faults and sedimentary formations within it
摘要济阳坳陷由于受到多期构造运动的影响，在前第三系古地形高点背景上广泛发育同沉积背斜构造，然而由于坳陷在断陷期基底滚动式沉降，造成挠曲顶部的塌陷，形成复杂的块断结构，使本区同沉积构造发生强烈改造，往往与各次级断层或沉积地层相复合，表现出独特的构造景观。 - The sedimentary formation can be summarized as rift bay filling sequence , epicontinental sea filling sequence , offshore debris lake basin sequence and inner continental lake basin sequence . a framework of sequence stratigraphy for the upper palaeozic strata is established in the area . the helan aulacogen of upper carboniferous in the west margin of ordos can be divided into 12 sequences , and most of the upper palaeozoic strata in the area can be divided into 15 sequences
本文对研究区内上古生界进行了层序地层学探讨，将本区沉积建造概括为裂陷海湾充填层序、陆表海充填层序、近岸碎屑湖盆层序和内陆湖盆层序，建立了研究区上古生界层序地层学格架，西缘贺兰拗拉槽上石炭统划分为12个层序，本区大部分地区上古生界可划分出15个层序，并全面地概括了层序演化各阶段的具体特征。 - Based on ore material sources , metallogenesis , occurrences , ore formation and wall rock alteration of gold ore deposits in the northest jiangxi province they are classified into four types i . e . magmatic hydrothermal gold deposit , volcao - subvolcano hydrothermal gold deposit , multi - sources hydrothermal gold deposit and heat underground water ( brine ) infiltrating gold deposit and 8 sub - types and the geological characteristics of the deposits are described and ore - forming control of sedimentary formation , structure and magmatic rocks on the formation of gold ore are summarized and gold ore - searching directions in the northeast jiangxi province are pointed out
依据成矿物质来源、成矿作用、矿床产出条件、矿石建造和围岩蚀变等因素，将赣东北地区岩金矿床划分为岩浆热液类、火山次火山热液类、多源热液类和地下热（卤）水渗滤类等4类8型，分述了各类（型）金矿成矿地质特征，总结了沉积建造、构造和岩浆岩对区内金矿的控制作用，指出了赣东北地区金矿找矿方向。
