云南东川播卡金矿区以往地质勘查资料的分析与评价

ANALYSIS AND EVALUATION OF THE PRVIOUS GEOLOGICAL EXPLORATION DATA OF BOKA GOLD DEPOSIT IN DONGCHUAN AREA,YUNNAN PROVINCE

自1995年发现播卡金矿以后,许多地勘单位在矿区及其外围开展了大量的地质、物化探、遥感工作,获得了海量地质数据和信息,并形成大量地质勘查资料和研究报告。但由于基础地质研究程度较低、矿产勘查工作不规范、矿产地质研究薄弱,造成以往资料的可靠性、矿体的连接和资源量估算的合理性、次生晕化探资料的归纳与整理、勘查工程部署和钻孔化探工作等方面存在许多问题。针对这些问题,有必要系统整理分析区内以往地质勘查资料,并对已形成的各类地质资料进行二次开发。

Since discovery of Boka gold deposit in 1995 huge volume of geological exploration data, such as geology, geophysical and geochemical survey, remote sensing etc. , have been acquired from the property and the surroundings and many reports compiled. However, the basic geological and mineral resource researches are in low level, the explorations not standard resulting in problems about reliability of the data, continuity of ore bodies and the mineral resource estimation, the induction and sort-out of secondary halo data of geochemical anomalies and arrangement of the exploration workings and drill holes. Facing to the problems it is needed to analyze and sort out systematically the data and make secondary development.
