Geochemistry of Rocks of the Oceans and Continents

The Geochemistry of Rocks of the Oceans and Continents (GEOROC) database is a collection of published analyses of igneous rocks and mantle xenoliths. It contains major and trace element concentrations, radiogenic and nonradiogenic isotope ratios as well as analytical ages for whole rocks, glasses, minerals and inclusions. Samples come from 11 different geological settings. Metadata include, among others, geographic location with latitude and longitude, rock class and rock type, alteration grade, analytical method, laboratory, reference materials and references.大洋与大陆岩石地球化学数据库（Geochemistry of Rocks of the Oceans and Continents，简称GEOROC）是一套汇集已发表火成岩及幔源捕虏体分析结果的专业数据库。该数据库包含全岩、玻璃质、矿物及矿物包体的主量元素与微量元素浓度、放射成因与非放射成因同位素比值，以及分析年龄数据。其样本覆盖11种不同的地质构造环境，元数据包括但不限于经纬度坐标标注的地理位置、岩石大类与岩石类型、蚀变程度、分析方法、检测实验室、标准参考物质及相关参考文献。
