| 摘 要： | 莲花山斑岩型钨－金矿床蚀变类型可以分作钾化、云英岩化、绢云母化、绿泥石化和青盘岩化。矿化表现为黑钨矿化、白钨矿－硫化物矿化、多金属硫化物矿化及黄铁矿化。蚀变在水平和垂向上具有分带性。由内向外由钾化向云英岩化、叠加蚀变带、绿泥石化＋绢云母化、青盘岩化转化。由浅向深，钾化增强，云英岩化减弱，被叠加蚀变带和绿泥石化及绢云母化所代替。矿化由内向外表现为由黑钨矿化向白钨矿化、多金属硫化物矿化、黄铁矿化转变，由浅向深由钨矿化转变为金矿化及多金属硫化物矿化。与典型斑岩型矿床蚀变分带对比，莲花山斑岩型矿床不同原岩类型蚀变特征变化较大，矿化则表现出富钨、金贫铜及钨金共同产出的特征。

| Abstract: | Alterations of Lianhuashan porphyry-type W Au deposit include K-feldspar and biotite alteration, greisenization, sericitization, chloritization and propylitization. Mineralizations include wolframite, scheelite-sulfide, multimetal sulfide and pyrite mineralization. Alteration and mineralization zone vertically and horizontally. K-feldspar and biotite alteration changes into greisenization, overprinting alteration, chloritization+sericitization and propylitization from the intrusive outward. K-feldspar and biotite alteration becomes intensive and greisenization becomes weak which is substituted by overprinting alteration zone and chloritization+sericitization with depth increasing. Mineralizations change from wolframite to scheelite, multimetal sulfide and pyrite mineralization from the intrusive outward. The shallow tungsten mineralization changes into the deep gold mineralization. The alteration is different from typical porphyry-type copper deposits and the mineralization is characterized by rich tungsten and gold and poor copper. |
