| 中文摘要: |
| 乳山金矿黄铁矿形态十分复杂,经统计共发现6种习性晶36种形态,{210}为优势晶习,其次为{100}、{311}和{111}.以石英-黄铁矿-菱铁矿组合为特征和以镜铁矿-多金属硫化物-方解石组合为特征的早、晚两个成矿期早阶段{100}习性晶黄铁矿较发育,晚阶段{111}习性晶较发育,主成矿阶段黄铁矿形态最为复杂,以{210}、{311}习性晶为特征。黄铁矿的形态在矿化地段上部相对富{100},下部相对富{111}.富矿段{210}和{311}习性晶含量较高,而贫矿段{100}含量较高。{111}习性晶在富矿段相对较发育,但相关性不明显。以YPY=-3C{100}+C{210}+2C{311}为要素对乳山金矿金青顶矿区Ⅱ号矿体所在矿化地段填图表明,黄铁矿形态可作为石英脉型金矿矿化强度预测的有效工具。 |

| The morphology of pyrite from Rushan gold mines is quite complicated. A statistics recognizes 6 habit crystals and 36 forms with {210} as its dominant habit and subsequently {100} and {111}.It is known that {100} habit crystals are developed in the early stages and {111} in the late,whereas more complicated with {210} and {311} in the major ore-forming stages of the quartz-pyritesiderite assemblage chracterized early metallogenic epoch and the specularite-polymetallic sulphide-calcite assemblage characterized late epoch.The upper portion of the mineralized zone is relatively rich in {100} and the lower in {111}. The strongly auriferous block contains high {210}, {311} and somewhere {111} habit crystals and the barren block contains relatively high {100}.Taking YPY=-3C{100}+ C{210}+ 2C{311} F (here C represents for content) as cartographic unit to map the mineralized zone where orebody No. 2 lacated in Jinqingding gold mine,some significant results in mineralization intensity predicting are obtained. |
