摘　　要：山东省泰安朱家庄自然硫矿床,赋存于鲁西断隆古近纪汶东陆相盆地。自然硫矿层在汶口组二段上亚段,泥质灰岩-含泥灰岩-含云灰岩-石膏岩韵律层中的白云岩-石膏岩层段发育。自然硫以胶态、晶态、土态3种形态产出,可划分为顺层型、准顺层型、斑杂型及不顺层型4大类10余种矿石类型。从矿区去膏化作用普遍、自然硫与石膏-硬石膏分别富集轻-重同位素的特征、油气显示明显及地下水主要径流方向自然硫矿化最强等各种证据,表明该矿属生物后生成因的矿床。ZhuJiazhuang native sulfar deposit occurrence in Wendong continential basin of Gujin period. West of Shandong province block dome. SuLfur ore bed occurrence in submember of the No.2 menlber of wenkou group, which is dolomite-gypsolith bed in rhythmite of limestone-much-bearing limestone-dolomite beating limestone-gypsolith. Native sulfur occurrence at 3 types, which are colloidal, crystalline and earthy state. It can be divided into four types and over ten species of ore types. The four tyres are bedding parabedding, prophyritic and unbedding. All kinds of evidence, widerspread degypsifi cation, light and heavy isotope separated rich in native sulfur and gypsum-anlydrite, show of oil and gas and native sulfur mineralization intense in the direction of ground water folw. Indecate that the deposit is a type ofbiogenic and epigenetic ore deposit.
