Pine Creek - Kombolgie VTEM (TM) AEM Survey, NT: Revised EMFlow Conductivity Estimates to 2 km Depth

Phase-1 data, that is, contractor quality-controlled and quality-assessed data for Kombolgie, were released during 2009. New EMFlow data, that is data generated using a new EMFlow version are included in this data release. The data and products described in this report are contained on the accompanying DVD. The main products included in this data package include: sections, conductance grids and an AEM Depth of Investigation grid. The data is provided in formats which can be viewed on most computer systems. They include, JPEG (.jpg) with associated world files for easy use in geographic information system (GIS) packages, ER Mapper grids (.ers), ESRI shape files (.shp) of the flight path, and point-located ASCII data with relevant metadata for derived products.The outcomes of the Pine Creek AEM Kombolgie survey include mapping of subsurface geological features that are associated with unconformity-related, sandstone-hosted Westmoreland-type and Vein-type uranium mineralisation. The data are also capable of interpretation for other commodities including metals and potable water as well as for landscape evolution studies. The improved understanding of the regional geology to greater than 1500m resulting from the enhanced EMFlow survey results will be of considerable benefit to mining and mineral exploration companies.

第一阶段数据，即孔博吉（Kombolgie）项目经承包商开展质量管控与质量评估的数据集，于2009年正式发布。本次数据发布还包含新型EMFlow（EMFlow）数据，即采用新版EMFlow生成的数据集。本报告所述的数据与产品均存储于随附DVD光盘中。本数据包包含的核心产品包括：剖面数据、电导网格以及AEM（航空电磁，Airborne Electromagnetic）探测深度网格。本数据集采用适配多数通用计算机系统的格式提供，具体包括：附带关联世界文件、可便捷用于地理信息系统（GIS）软件的JPEG（.jpg）格式文件；ER Mapper网格格式（.ers）文件；记录飞行路径的ESRI形状文件（.shp）；以及带有衍生产品相关元数据的点位定位ASCII数据。松溪（Pine Creek）航空电磁Kombolgie测量项目的成果涵盖了与不整合相关、砂岩赋存的威斯特摩兰型及脉型铀矿化相关的地下地质特征填图。该数据集还可用于金属矿产、饮用水源等其他矿产资源的解译分析，以及地貌演化研究。通过优化后的EMFlow测量成果，对1500米以深区域地质的认知得到显著提升，这将为矿业及矿产勘探企业带来显著裨益。
