盆地，地层学和年代学

地层学者编译了大数据集，以解决地球科学中的大问题，以探索地球历史和盆地的进化。Bruker的工具可以通过手工样本，露头，核心和插条对地球化学和矿物学进行可靠且可重复的测量。

介绍

研究地层继承和深度时间的新工具

盆地中的沉积记录记录了地球的历史。山链的出生，生与死记录在盆地沉积物中。沉积物记录了过去，气候，环境和地面表面的演变的历史。布鲁克（Bruker）的分析工具赋予地质学家能够了解趋势，可视化结构并更好地理解塑造地球的动态过程。

化学地层学Enables Correlations and Reservoir Characterization with High-resloution Elemental Data

化学地层学可以是高度风化或缺乏独特特征的继任的特别有效的研究工具。例如，红床通常是几百米的堆叠类似岩石，容易天气，但独特的化学特征赋予了详细的相关性。

化学地层学utilizes chemical relationships in sedimentary rocks to understand stratigraphic relationships. Elemental chemostratigraphy is an accessible method that can be applied to cuttings, core, and outcrops using X-ray fluorescence (XRF). Elemental trends and ratios are an effective tool for correlation, even in thick successions of unconventional shale or red beds where marker beds are elusive. Elements can also be effective paleoenvironment proxies, indicating chemical conditions during deposition. For example, detrital sedimentation rates in predominantly carbonate system can be tracked by the covariance of aluminum (Al), potassium (K), silicon (Si), titanium (Ti), and zirconium (Zr). In mud-rich systems the accumulation of molybdenum (Mo) and uranium (U) can indicate anoxic bottom water conditions. Portable XRF (pXRF) and matrix-matched calibrations make collecting chemical data on rocks easier than ever. Click below to learn more.

Repeatable and Quantitative Lithostratigraphy with Innovative Mineral Analysis

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.
通过将岩性型连接到相或亚面，例如跟踪下斑 - 斑点 - 帕雷索尔关系，对古环境进行高分辨率重建。
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.

创建引人注目的可视化，以便快速对地层断裂的评估，这是所有类型的石油和天然气井中的薪水。

这main technologies used to generate lithostratigraphy logs are自动矿物学,X-ray diffraction (XRD)和FTIR 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)和傅立叶变换红外（FTIR）光谱可用于识别矿物质，并且可以将数据分组到岩性型中进行记录。

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:
