- 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 、按照成矿系列理论的学术指导思想，将研究区华里西期铜矿床成矿系列划分为四个成矿系列亚系列： 、晚泥盆?早石炭世延东?土屋?三岔口与中酸性岩浆侵入活动有关的cu 、 mo 、 au矿床成矿亚系列、早石炭世与岩浆作用有关的铁、铜、金、银矿床成矿亚系列、中石炭世与岩浆作用有关的cu 、 fe 、 ag 、 au矿床成矿亚系列、晚石炭世-早二叠世与幔源基性?超基性岩有关的铜、镍、铂族矿床成矿亚系列并从地层、岩浆岩、控矿构造、地球化学、成矿特征等方面对各成矿亚系列进行了详细论述。 - 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
文章在综合分析、比较各矿床的矿床地质和地球化学特征的基础上，还结合了研究区的地质背景资料，研究了前人的成果和认识，初步分析了区域不同类型铜矿床的形成机制，探索性地提出了各类型铜矿床的成矿模型，以期为该区的找矿勘探和矿产开发提供理论依据。
