摘　　要：应用高级光学显微镜、化学分析、X射线粉晶衍射物相分析、电子探针、扫描电子显微镜等多种手段对吉林白山金矿金的赋存状态进行了系统的研究。结果表明,该矿床主要矿石类型为硅化构造角砾岩型,金矿物种类有自然金、含银自然金和银金矿,石英是金的主要载体矿物。金矿物的赋存形式有粒间金、包裹金和裂隙金,分别占89.27%、6.42%和4.31%。金矿物以微粒金为主,大小为0.001～0.005mm,形态以粒状、麦粒状居多,金矿物成色高,矿床应属中偏高温成因。The occurrence and distribution of gold in the Baishan gold mine, Jilin Province, were studied in detail by means of a senior optical microscope, chemical analysis, X-ray diffraction phase analysis, electron microprobe analysis, scanning electron microscopy, etc. in this paper. The conclusions are drawn as follows ： the main type of mineral ores is the silicated and structural breccia. Aurum occurs as natural gold, silver-bearing natural gold and electrum, and quartz is the major gold carrier. Gold occurs in the three states： intra-granular state, enclosure forms and fillings in fissures, accounting for 89.27%, 6.42% and 4.31%, respectively. The gold minerals vary in size between 0. 005 -0. 001 mm and are largely granular shaped and wheat-shaped. The gold minerals have high contents of （Au/ Au ＋ Ag）, which suggests the deposit could be formed under moderate to high temperature conditions.
