Three Dimensional Aggregate Resource Visualisation using Geo-Electrical Tomography

三维电阻率层析成像（ERT）是近年来最重要的地球物理成像技术之一。尽管它具有适用性和潜在的效益，但尚未应用于砂石资源。采用的主要障碍是缺乏适当的数据处理和展示系统，使现场人员能够直观地了解与商业运作有关的知识。该项目旨在将3D ERT、现有GIS、井眼数据和其他相关现场特定背景信息联系起来，为复杂的砂砾沉积提供非侵入式可视化和评估。这将提供决策支持和数据管理工具。这是及时的，因为现在正在开发的许多英国砂和砾石矿床都是复杂的（例如冰川和绿地矿床），显示出高度的结构和成分异质性。

3D electrical resistivity tomography (ERT) is one of the most significant geophysical imaging developments of recent years. Despite its suitability and the potential benefits it has not been applied to sand and gravel resources. The main barrier to take-up is the lack of an appropriate data processing and presentation system, to allow knowledge relevant to commercial operations to be visualised by site personnel. The project aims to link 3D ERT, existing GIS, borehole data and other relevant site-specific contextual information to provide non-invasive visualisation and evaluation of complex sand and gravel deposits. This will provide a decision support and data management tool. This is timely as many UK sand and gravel deposits now being exploited are complex (e.g. glacial and Greensand deposits), displaying a high degree of structural and compositional heterogeneity.
