| 中文摘要: |
| 湖南郴州金狮岭地区是一个潜在的Pb-Zn-U多金属矿化区,对该地区进行了系统的地面伽马能谱测量,并应用分形理论对U测量数据进行分析.该区U含量分布具有明显的双分形特征,表明该区受到了多期地质作用的叠加.第一个分形分维值很小(D1=0.083),代表了第一次地质作用和低的U含量背景值;第二个分形的分维值较大(D2=2.523),代表了后期地质作用特别是成矿作用的叠加,并有较强的U富集作用.其分形临界值(3.37 μg/g)可作为该区铀矿化的异常下限值.结果还表明该区U异常区分布较大且连续性好,具有较好的成矿远景. |

| Jinshiling district,loated in Chenzhou city,Hunan province,is a potential Pb-Zn-U polymetallic mineralization area.The terrestrial gamma ray spectrometry measurements were carried out systematically in this district,and the measured data was analyzed using fractal theory.The results demonstrate that the distribution of U content in this district behave obvious bifractal characteristics,which indicats that this area is superimposed by multistage geological processes.The first fractal dimension is very small (D1=0.083),which represents the first geological process and low U content background value,and the second fractal dimension is large (D2=2.523),which represents the superposition of late geological processes,especially the mineralization,and a strong U enrichment.The fractal critical value (3.37 μg/g) can be used as the lower limit value of uranium mineralization in this district.In addition,the results show that the U anomaly area in this district has a large distribution and good continuity,indicating a good metallogenic prospect. |
