盆地，地层学和年代学

岩石地层学是基于其岩性特性的岩石系统组织。布鲁克（Bruker）的矿物识别工具可实现一种定量岩性地层学或岩性型的类型。岩性分型使用分类技术，例如聚类分析或深度学习，将大型数据集分组为有意义的类似岩相的分组。这些分组可用于地层学和盆地分析中：

• Improve lithostratigraphy correlations by recognizing diagnostic patterns in lithotype occurrence that may not be obvious through optical observations of core, outcrop, or cuttings.

• Conduct high-resolution reconstructions of paleoenvironment by connecting lithotypes to facies or sub-facies, such as tracking underclay-paleosol relationships.

• 通过消除许多井中的地层观测值的重复性，使区域序列地层或预测地层框架更加健壮。

• Collect lithologic data from cuttings and other hard to describe geologic samples, empowering deep-time studies in locations without core or outcrop.

• Create compelling visualizations that enable quick-look assessment of formation breaks, the occurrence of pay in all types of oil and gas wells.

这main technologies used to generate lithostratigraphy logs areautomated mineralogy,X-ray diffraction (XRD)andFTIR spectroscopy.Automated mineralogygenerated quantified maps of minerals from thin sections or grain mounts. Mineral textural information and mineral associations can be used to group results into lithotypes and generate lithology logs, and calculated density or rock property logs.X-Ray diffraction (XRD)and傅立叶变换红外（FTIR）光谱can be used to identify minerals and the data can be grouped into lithotypes for logging.

Chronostratigraphy is concerned with establishing the general ages of stratified rocks. Studies of successions of rocks reveal depositional processes through investigations of chemistry, magnetism, fossils, striatal stacking patterns, and superposition relationships to reveal the temporal correlative relationships and the history of the earth. Geochronology is concerned with establishing the absolute age of any rock unit, and in sedimentary geology understanding the timing of processes such as erosion and deformation. The identification, isolation, and analysis of dateable minerals (e.g. zircon) is a primary tool used in both chronostratigraphy and geochronology. Bruker is innovating methods to streamline this process:

• 这M4 TORNADOmicro-XRF geochemical mapping of large samples allows for quick-look assessment of zircon fertility of samples either through geochemical proxies or by direct mineral identification withM4 AMICS.

• 友善对于scanning electron microscopes provides automated mineralogical mapping of thin sections and polished grain mounts to identify and quantify dateable minerals.友善can be configured to identify target minerals and collect high-quality long-count spectra for quantification.

• BothSEM AMICSandM4 AMICS使工人能够精确地在滑梯，薄截面或谷物安装座上定位可数据矿物的空间坐标。这些坐标可以导出到LA-ICPMS。这可以减少所需的样品加工和浓度的总量，包括在矿物分离中手提采摘谷物。
