探索钻探将未知的钻探变成已知。这种“核心”活动可能是矿产勘探工作流中最有价值的资产之一。在钻石钻石期间提取的核心通常由熟练的地质学家描述,并且以及岩土表征进行其他地球化学和矿物分析。
Bruker is pioneering new technologies and methods to extract more useful and scalable information from core, aiding geologists on the ground and in the exploration office. As a critical link to the subsurface, core analysis is the best opportunity to characterize the products of mineralization and alteration, from the ore body scale to the sub-grain scale, allowing development of refined ore system process models. Non-destructive and minimally destructive tools can characterize elemental concentration, mineralogy, and texture to construct 3D subsurface deposit models and constrain predictive exploration strategies.
Non-destructive elemental and mineral logging of core provides objective high-resolution analytical data to identify sweet spots, mineralization, and alteration. Bruker portable and handheld analyzers are used to collect depth-registered geochemical and mineralogic data in the field or the core shack. The high-resolution nature of this data means that even small prospective zones of mineralization or alteration can be identified without dilution, improving distal identification of ore systems. Field collection of data provides near-instantaneous geochemistry that can be used for:
核心中主要,次要元素和微量元素的空间分布的可视化源是对矿化和改变过程的理解。Micro-XRF在小于<20µm的分辨率下提供大样本地球化学映射,可以在地质过程框架内进行情境化特征。自动化矿物学在微型XRF中添加是一个新兴领域,有望增加快速和可重复的岩石学表征的新维度。用于核心分析布鲁克的M4 TORNADOseries of instruments can be set for rapid data collection on-site or in the core shack:
Many mineralization processes leave a record at the micron scale. Scanning electron microscopy (SEM) characterization is the most accurate method available to visualize and analyze processes at this scale. Bruker’s automated mineralogy and large area elemental mapping solutions by automatedEDS用反向散射选举(BSE)成像进行X射线映射,在分辨率下至〜1 µm时提供了详细的分析。单击此处以了解有关岩石特征的更多信息,以探索微分析。
Traditional mineral analysis of rocks views a 3D world in 2D. Analysis of thin sections and core slabs in optical microscopes, SEMs and micro-XRF all require extrapolation from a single plane to understand a 3D object. High-resolution 3D X-ray Microscopy studies on core allow for non-destructive observations of the third dimension. Bruker’sSkyscan系列of X-ray microscopes works with other methods to produce detailed information on the shape, size and inter-relationships of geologic features. When combined with automated mineralogy from SEM or micro-XRF the possibility opens to develop fully comprehensive models of ore distribution at the micron-scale, better defining mineralization processes and predict comminution and other processing behaviors.
