| 中文摘要: |
| 郁山铝土矿床是2006年河南省地质调查院在豫西新安县发现的一个大型隐伏铝土矿矿床。文章通过利用显微镜、X衍射、扫描电镜、电子探针、红外光谱、热重等手段分析发现,郁山铝土矿中的矿物组成有:铝矿物,黏土矿物,铁矿物,钛矿物,非晶质,其它微量矿物(锆石、电气石、硫磷铝锶矿、明矾石、斜长石、钾长石、石英、方解石)六大类。非晶质组分的存在是华北陆块南缘铝土矿研究中物质组分方面的一个突破,为华北陆块南缘铝土矿的物质来源,成矿过程以及物质成分变化研究提供了线索和证据。 |
| 英文摘要: |
| Yushan bauxite deposit is a large blind deposit discovered in Xinan county in the west Henan province in 2006 by Henan Geological Survey Institute. Results of microscope observation and analysis of X-ray differaction, scanning electron microscope, electronic probe, infrared spectroscopy, thermogravimetry etc., show that aluminium mineral, clay mineral; iron mineral, titanium mineral, amorphous mineral and rare mineral (zircon, tourmaline, svanbergite, alunite, plagioclase, K-feldspar, quartz, calcite) occur in bauxite. The first discovery of amorphous mineral in the deposit on the south margin of north China landmass is a breakthrough which provides reliable clues and proofs for its material source and ore-forming process as well as the changes of the composition. |
