| 中文摘要:柿竹园钨多金属矿床中锰质矽卡岩由锰铝榴石、铁铝—锰铝质榴石、蔷薇辉石、锰橄榄石、日光榴石、硫锰矿、含锰次透辉石、富锰金云母和菱锰矿组成。其生成于钙质矽卡岩的退化蚀变之后，与云英岩钨多金属矿化有着密切的时空关系。从近接触带到远接触带，锰质矽卡岩矿物组合及各种锰质矿物中的锰含量均逐渐上升。 |

| Abstract:A mangalioan skarn in the Shizhuytlan supergiant W-Sn-Mo-Bi-Be deposit is studied in the present paper.It consists of spessartilie, almalidinic-spessartinie garnet, rhodoliite, tephroite, helvite, alabandine, Mn-bearing salite, Mn-rich hedenbergite, Mn-rich phlogopite and rhodoohrosite and spacio-temporally develops together with the greisenization and relevant mineralizations after calcie skarnization and retrograde alteration. From proximal to distal contact
Zones, its mineral assemblages become increasingly complicated and the manganese content of their various minerals is getting higher and higher. The complicated mineral assemblages of the manganoan skarn and their spaciotemporal distribution apparently prove the evolutional direction of the skarn in the Shizhuyuan polymetallic tungsten deposit. |
