| 中文摘要: |
| 湖岽矿区处于南岭东西向构造带与武夷山北北东向断褶带的复合部位。区内有夕卡岩型、石英细脉带型和石英大脉型3类钨锡多金属矿化体；夕卡岩型钨锡多金属矿化体1条,呈似层状,长600 m,铅直厚度6～18 m,钨品位0.084%～0.256%,锡品位0.194%～0.41%；石英大脉型钨锡多金属矿化体17条,延长100～400 m,厚度0.05～0.5 m,钨品位0.024%～1.580%,锡品位0.104%～0.152%；石英细脉带型钨锡多金属矿化带6条,长320～550 m,宽12.6～41 m,钨品位0.021%～0.113%,锡品位0. 025%～0.143%。文章重点阐述了矿床的地质特征,分析了成矿条件和成矿机理,建立了多位一体成矿模式,探讨了矿床成因,以期对矿区进一步找矿及外围找矿等有一定意义。 |
| 英文摘要: |
| The Hudong tungsten-tin polymetallic deposit is located in the junction part of EW-trending Nanling tectonic belt and NNE-trending Wuyishan fault fold belt. There are three types of tungsten-tin polymetallic mineralization i.e., skarn type, quartz veinlet type and quartz vein type in the deposit area. Among them, it has outlined one skarn type tungsten-tin mineralization body, which distributed in the form of stratoid. The tungsten-tin orebody is 600 meters long with true thickness of from 6 meter to18 meter, and tungsten grade ranges from 0.084% to 0.256% and tin grade ranges from 0.194% to 0.41%. Totally 17 tungsten-tin-bearing quartz veins were outlined, the mineralized quartz vein ranges from 100 m to 400 m with a true thickness of from 0.05 m to 0.5 m, and the tungsten grade ranges from 0.024% to 1.580%, tin grade from 0.104% to 0.152%. Totally 6 tungsten - tin mineralization quartz veinlets were delineated and the length of mineralized veinlet ranges from 320 m to 550 m with the true thickness of from 12.6 m to 41 m, the tungsten grade ranges from 0.021% to 0.113%, and tin grade from 0.025% to 0.143%. The deposit geological characteristics of ore deposit was mainly described, metallogenic conditions and metallogenic mechanism were analyzed, and trinity metallogenic model of the deposit was established, finally the deposit genesis was discussed. The integrated study result will provide significant implication for the next step exploration in the depth of the deposit and the surrounding deposit area. |
