| 摘 要： | 对广西岩溶区三个铅锌硫化物矿床风化带观测结果表明，中低山岩溶区硫化物矿床具有更强烈的风化淋滤作用，但次生晕面积较小；岩溶平原区硫化物矿床风化与元素表生迁移特征较相似于非岩溶区的情况，表现在可产生较宽的ｐＨ偏低带和较大面积的次生晕

| Abstract: | The result obtained from surveying 3 lead and zinc sulphide deposits in karst area of Guangxi shows that the sulphide deposits in low mid mountain area are more extensively weathered and leached,but the area of secondary halos is smaller; the weathering and elemental exogenic migration characteristics of metallic sulphide deposits in karst plain is relatively similar to those of non karst area with wider pH lower band and larger secondary halo area. |
