| 中文摘要: |
| 冯家山夕卡岩型铁铜矿就水化学异常清晰衬底高，最有效的找矿指标是Ｃｕ６２＋和ＳＯ＾２－４其次是Ｍｏ＾４＋，Ｚｎ＾２＋和Ａｇ＾＋，对于夕卡岩型矿床，ｐＨ值无异常，没有明显的指示意义，研究表明，亚热带气候条件下，由于温度高，雨量多，促进了硫化物的氧化面补偿了降雨的稀释作用。因此，水化学方法是十分有效的找矿方法，旱季和雨季不影响方法效果。 |
| 英文摘要: |
| The hydrochemical anomalies of the Fengjiashan skarn Fe-Cu deposit are characterized by high contrast. Cu 2+ and SO 2- 4 are the most effective indicators for geochemical prospecting, while Mo 4+ ,Zn 2+ and Ag + take the second place. pH shows no anomaly and has no significant meaning for skarn deposit.The research indicates that under the condition of subtropic region, owing to the abundant rainfall and the high temperature , the promoted oxidation of sulfides can compensate the dilution by rain. The hydrochemical prospecting serves as an effective prospecting method which may not be affected by dry or rainy season. |
