| 中文摘要: |
| 布罗肯希尔(BROKEN HILL)超大型铅锌银矿以其规模巨大(＞5500万t)、品位高(Pb+Zn＞25%)而称著于世。在其矿山外围区域开展找矿勘查工作,具有较好的区位优势。裂谷构造是本区成矿最基本的条件,两期剪切作用分别对应了两次重要的成矿活动,形成了该区域丰富的有色金属矿产资源。基于地、物、化、遥地质矿产勘查工作,综合研究以往地质成果资料,发现在其南部小布罗肯希尔(Little Broken Hill)、北部银城(Silver)、托里万吉(Torrowangee),具有寻找Sedex型铅锌矿的潜力, 在南东芒特达林(Mount daring)和北西部坎塔帕(KANTAPPA)韧性剪切带附近,铜金矿的找矿前景较好。 |
| 英文摘要: |
| Broken hill is well known for its supper large Pb-Zn-Ag deposits in which the scale is larger than 55 million tons and the Pb+Zn grade is higher than 25%. The basic metallogenic condition of the area is rift structure and the two shearing action corresponding to the two important metallogenic activity formed rich mineral resources of nonferrous metals. There is geographical advantage for carrying out the prospecting exploration work outside the mining area. Based on the research about geological features of the deposits, metallogenic information including geophysics, geochemistry and remote-sensing was analyzed in this paper. Results showed that there was potential to look for sedex-type Pb-Zn deposit in the north of Silver and Torrowangee and in the south of Little Broken Hill. At the same time, there was better exploring foreground for Cu-Ag deposits nearby the ductile shear belts of the south-east Mount Daring and north-west Kantappa. |
