AMICS Automated Mineralogy in Mineral Exploration

通过将数百个样品表征到数百个样品或使用岩石学显微镜，很难通过将数十个样品表征到数百个样品来进行客观的矿物识别和定量。自动化矿物学允许在微米，薄截面和手部样品尺度上重复收集矿物学信息，提供统计上强大的数据，包括矿物质识别和模态丰度，颗粒和矿物晶粒尺寸分布，矿物质纹理数据等。布鲁克的自动矿物学解决方案是Amics。该软件可以作为矿物探索中直接使用的两种互补解决方案的一部分实施：

M4 TORNADO AMICSimplements Bruker's AMICS software directly on theM4 TORNADO和M4 TORNADO PLUS为了允许对可能直接与主要和微量元件地球化学图直接集成的最小样品进行快速自动矿物学扫描。由于M4龙卷风系列的仪器足够强大，可以部署到现场办公室和勘探营地，并且不需要专业的样品准备设备，因此该解决方案允许实时数据反馈以支持探索目标。利用M4 TORNADO AMICSto support:

岩性型和更改直接在钻头上映射，以增强存款模型并验证视觉或地球化学日志工具做出的解释
Accurate identification and characterization of fine-grained ore and alteration minerals
Selection of samples for more expensive characterization techniques such as SEM-EDS mapping or SEM-based automated mineralogy
Pre-screening of samples for use in prospectivity and fertility workflows (e.g., RIMS), including analysis of stream sediment, soil or till samples without the need for exhaustive sample preparation.

Automated Mineralogy for Scanning Electron Microscope

Where mineral relationships are needed at scales below that resolved by micro-XRF,SEM的友善提供矿物和岩石表征的解决方案。使用SEM Aimics：

通过显微镜o-XRF for Rock Characterization in Mineral Exploration

Modern explorationists are presented with a myriad of tools to aid targeting, detection and characterization of new ore deposits. Fundamental to the exploration process is robust characterization of rocks – hand samples taken from outcrops, drill chips generated through RC drilling methods, or diamond drill core. While skillful geologists may accurately identify minerals in hand sample and create robust logs that guide sampling for geochemistry and construction of deposit models, new and evolving technologies are providing rapid and repeatable methods for rock characterization.

通过显微镜o-XRF scanning provides rapid visualization of major and trace element geochemistry at the hand-specimen and thin section scale, on minimally prepared samples. Bruker'sM4 TORNADO一系列的Micro-XRF仪器坚固耐用，使部署到现场站点或办公室，并且不需要专业实验室人员操作或减少数据。使用M4 TORNADO或者M4 TORNADO PLUSto enable:

快速扫描粗切钻或钻头托盘以生成主要，次要和微量元素地球化学地图
quickly evaluate ore and alteration mineralogy and confirm visual logs and direct ongoing logging strategies
通过在可比尺度上提供直接地球化学数据来验证高光谱或其他记录技术数据
使用地球化学图来计算扫描中的整个样品或子域中的整个岩石组合物，用于岩性型和计算改变指数
迅速构建数据集，以在钻井程序中提供更准确的矢量，并为区域勘探计划提供饲料存款模型。

Characterization at the Micron Scale - Mapping by SEM-EDS

During different stages of exploration needs arise for more detailed investigations of samples that may be beyond field or forward-deployed lab solutions. Micron-scale rock and mineral characterization is commonly needed to understand complex paragenetic relationships, shedding light on the mineralizing processes and event sequences that can be used to build more comprehensive deposit models to guide ongoing exploration.

Rock and mineral characterization driven bySEM-based EDS解决方案提供：

重要的矿石和脉管矿物质之间的详细质地和时机关系
与矿石相关的矿物质中的组成分区以定义矿石沉积事件bob综合客户端app
对细粒的变化产物的更集中的组成分析，以验证其他现场地球化学技术并对勘探模型提供信心

Adding to the arsenal of characterization techniques available in the mineral explorationist's toolkit, FTIR and Raman spectroscopy build on elemental scanning techniques to provide addition mineral chemical and structural information. Infrared and Raman spectroscopy allow accurate identification of minerals where elemental signatures are similar but their crystal structures are not. Applications include:

distinguishing specific species of alteration products such as clay, oxide or sulfate minerals, which are important for understanding alteration facies and locations in hypergene, supergene or oxide zones.
Presence of organic materials that can be important exploration indicators in some deposit environments

In-Situ Study of Lazulite from Graves Mountain, Georgia, USA

The traditional bulk mineralogy approach is to reduce the sample to a homogenous powder and analyze with a divergent beam (Bragg-Brentano) geometry. Grinding is not always a practical option, due to rarity of a given specimen or the desire to characterize the spatial relationship of multiple phases within an assemblage. Microanalysis techniques offer the ability to analyze the sample in its native state, easing analysis of the individual constituents.
