【摘要】 黔西北地区是一个裂谷盆地构造区,盆地内发育铅锌矿床,矿化受断裂和地层的联合控制。从区域地球化学、水系沉积物地球化学、地层地球化学以及地球化学块体等几个方面的特征进行了较为系统的研究。断裂两侧及断裂交汇处、岩体接触带、Pb-Zn组合异常区以及地球化学块体的浓集中心为该区的主要找矿标志,应注重多元素组合异常区内的研究。另外,该区具条带状的地球化学块体浓集带和高强度的Pb、Zn元素化探组合异常之特点,具有良好的Pb、Zn元素成矿背景;建议进行综合研究,尽早发现大型甚至超大型铅锌矿床。更多还原

【Abstract】 The northwestern Guizhou Province is located in a rift basin with some lead-zinc deposits controlled by the faults and strata.The authors discusse systemically based on several aspects from studies on regional geochemistry,stream sediment geochemistry,geochemical stratigraphy and geochemical block etc.Important prospecting criteria in the area include: located at the both sides of the fracture and/or adjacent to fracture junction,at rock contact zone,within Pb-Zn anomalous zones and in the concentration centers of geochemical block.Special attention should be paid to the comprehensive,anomalous zones consisting of several elements.In addition,the northwestern Guizhou Province are featured by banded geochemical concentration blocks and by intensely enrichment of Pb and Zn,thus is highly potential for hosting the Pb-Zn deposits.It is suggested that more comprehensive studies are need to find some large,even superlarge lead-zinc deposits.更多还原
