摘要湖南沅陵雪峰古陸邊緣上石炭統主要包括下列巖相類型：沖積扇砂礫巖相、前濱海灘砂巖相、淺灘碳酸鹽相及混積巖相、潮下碳酸鹽巖相及灘后局限碳酸鹽巖相。Abstract : to the principle and project that tu guangazhi proposed in 1990, the gold ore deposits in qinling ( shaanxi ) may be classified into fouowing types : archean high - grade gneiss type, fine grained fragmental rock - carbonate rock - silicilith type, metamorphic fragmental rock type, volcanic rock type, explosive breccia type, intrusive rock exo - and endo - contact zone type. inthis paper, the geological characteristics, metallogenic geological setting, the source of ore - forming materials, digenic mechanism and metallogenetic epoch of gold ore deposits are also discussed
文摘:參照塗光熾先生（ 1990 ）提出的礦床類型劃分原則與金礦分類方案，將陜西秦嶺地區原生金礦劃分為太古界綠巖建造型、細碎屑巖-碳酸鹽巖-硅質巖建造型、變質碎屑巖型、火山巖建造型、隱爆角礫巖型和侵入巖內外接觸型金礦，並對各類型金礦的地質特徵、成礦地質背景、成礦物質來源、礦床形成機制及形成時代等問題進行了論述和討論。Abstract : according to the composition, the thermal - water sedimentary rocks of yinmin formation in the dongchuang copper ore field can be divided into nine types, of which skarnoid, cupric magnetite carbonate, paracontemporaneous breccia formed in thermal water processing are confirmed and named in this study
文摘:東川銅礦田因民組熱水沉積巖根據主要成分可分為9大類，其中類夕卡巖、含銅磁鐵碳酸鹽巖、熱水膠結準同生角礫巖為本次研究確定和命名，其礦物組合、微量元素、稀土元素等地球化學特徵表明：它們是海底火山噴流沉積作用的產物。Sedimentological and provenance data from tuchengzi formation in nuyingzi - goujiadian basin provide information about the links between erosional unroofing of adjacent thrust sheets and deposition within the basin. through field mapping, measured sections, and sedimentological analysis, we arrived at the following conclusions : 1
