PetDB

PetDB, the Petrological Database, is a web-based data management system that provides on-line access to geochemical and petrological data. PetDB is a global synthesis of chemical, isotopic, and mineralogical data for rocks, minerals, and melt inclusions. PetDB's current content focuses on data for igneous and metamorphic rocks from the ocean floor, specifically mid-ocean ridge basalts and abyssal peridotites and xenolith samples from the Earth's mantle and lower crust. PetDB is maintained and continuously updated as part of the EarthChem data collections.

PetDB，即岩石学数据库，是一款基于网络的数据库管理系统，它提供了对地球化学和岩石学数据的在线访问。PetDB汇集了关于岩石、矿物和熔融包体的化学、同位素和矿物学数据的全球性综合分析。PetDB的当前内容主要集中于来自海底的火成岩和变质岩数据，特别是中洋脊玄武岩、深海橄榄岩以及来自地幔和下地壳的异岩样品。PetDB作为EarthChem数据收集的一部分，得到维护并持续更新。
