The copper, iron, nickel and silver deposits might be assigned to four metallogenic series : i. the metallogenic subseries of copper, molybdenum, gold, silver deposit related to late devonian - early carboniferous basic - intermediate - acid hypabyssal intrusive - eruptive rocks ; ii. the metallogenic subseriesof iron, copper, zinc deposits related to early carboniferous basic - intermediate - acid volcanic - intrusive rocks ; iii. the metallogenic subseries of copper, silver, iron deposits related to middle - late carboniferous basic - intermediate - acid volcanic - intrusive rocks ; iv. the metallogenic subseries of copper, nickel and platinum group deposits related to late carboniferous - early permian basic - ultrabasic rocks ; 3, division of regional major metallogenic belts on the basis of the previous work conducted and by following the principles, grounds and methods of the division of metallogenic belts, areas and fields, . in light of this, metallogenic belts of grade iv were divided
1 、按照成礦系列理論的學術指導思想，將研究區華里西期銅礦床成礦系列劃分為四個成礦系列亞系列： 、晚泥盆?早石炭世延東?土屋?三岔口與中酸性巖漿侵入活動有關的cu 、 mo 、 au礦床成礦亞系列、早石炭世與巖漿作用有關的鐵、銅、金、銀礦床成礦亞系列、中石炭世與巖漿作用有關的cu 、 fe 、 ag 、 au礦床成礦亞系列、晚石炭世-早二疊世與幔源基性?超基性巖有關的銅、鎳、鉑族礦床成礦亞系列並從地層、巖漿巖、控礦構造、地球化學、成礦特徵等方面對各成礦亞系列進行了詳細論述。 -
This paper draws conclusions from the studies on five typical deposits which are distributed in the west of lanping - simao basin. these conclusions are as follows : the types of copper deposits are different because the geological backgrounds of this area in different period are different ; songjiapo copper deposit belongs to a typical porphyry deposit, its mineral liquid mainly come from the magma that formed the triassic eruptive rocks and effected by the subsequent geological action ; jinman copper deposit, shuixie copper deposit and kedengjian copper deposit are the hydrothermal type
文章在綜合分析、比較各礦床的礦床地質和地球化學特徵的基礎上，還結合了研究區的地質背景資料，研究了前人的成果和認識，初步分析了區域不同類型銅礦床的形成機制，探索性地提出了各類型銅礦床的成礦模型，以期為該區的找礦勘探和礦產開發提供理論依據。
