| 摘 要： | 用离子色谱法分析了山东玲珑金矿床石英等矿物包裹体的浸取液，结果表明其中存在相当高的短链羧酸盐和少量的草酸。黄铁矿和黄铜矿浸取液中羧酸的浓度比石英浸取液的高，早期成矿阶段的矿物包裹体中一元羧酸的浓度大于主成矿阶段和晚期阶段。

| Abstract: | Carboxylate composition of fluid inclusion leachate from quartz and other minerals in the Linlong gold deposit were detected by ion chromatography. The results show that the content of shortchain carboxylates (the dominant species are acetate and formate) is relatively high, but that of difuctional species (oxalate) is low. The carboxylate concentration is higher in the leachates from pyrite and chalcopyrite than that from quartz. The monofunctional carboxylate concentration is higher in early ore-forming fluid than that in middle to late ones. |
