| 中文摘要: |
| 通过对比各类铁矿储量-品位统计分布曲线,详细分析了其分布模式特点,认为不同类型铁矿品位分布模式同各类铁矿的成矿地质地球化学背景的复杂程度和成矿作用机制特征有关;从统计的角度论述了铁矿成矿总体趋势和各类铁矿成矿富集能力上的差异,指出了多期次、多阶段和多种成矿作用的同位叠加对矿床及工业富矿形成的重大意义。 |
| 英文摘要: |
| Based on contrast distribution curve of ore reserves-grade of each type iron ore deposit the authors consider that the distribution curve patterns of different type iron ore deposits are related to complexity of their geological and geochemical background and metallogenic mechanism characters. General tendency and enrichment power for different type iron deposit are statistically varied. Multiple superimposition of ore forming processes at the same place is important to formation of iron deposits and rich iron ore bodies. |
