摘　　要：位于冈底斯复合构造岩浆带东段的弄如日金矿,是由成都地质矿产研究所发现的具中型规模的岩金矿床。目前对于该金矿床的成因类型是属斑岩型金矿床,还是浅成低温热液型金矿床尚存争议。通过对弄如日金矿床与典型的斑岩型金矿床和浅成低温热液型金矿床详细的对比研究,指出弄如日金矿床在成矿地质背景、矿床地质特征、矿床流体包裹体特征等要素与斑岩型金矿床特征相差较大,而与浅成低温热液型金矿床的基本特征相符。因此认为弄如日金矿床属浅成低温热液型金矿床。The Nongruri gold deposit in the eastern part of compound tectonomagmatic belt is a medium-sized rock gold deposit discovered by Chengdu Institute of Geology and Mineral Resources.At present the type of this gold deposit is disputed.According to the comparative analysis of Nongruri gold deposit to typical porphyry and epithermal gold deposit,we find that Nongruri gold deposit has a large difference to porphyry gold deposit in ore-forming background, deposit geological characteristics,ore-forming fluid inclusion characteristics etc.,while basically accord with epithermal gold deposit.so that Nongruri gold deposit belongs to epithermal deposit.
