摘　　要：PetDB是目前海洋科学及地学领域最重要的基础数据库资源之一,是海底岩石地球化学数据库的旗舰,它为海洋地质和岩石地球化学专业人员提供了最好的"大数据"支持。PetDB综合了全球海底岩石、矿物和包裹体等的元素化学数据、同位素数据和矿物学数据,数据收录全面、完整、更新快,数据格式规范、统一,数据组织结构清晰,数据查询、输出方便快捷,用户体验感强。将面向国内同行详细介绍海底岩石地球化学"大数据"工具———PetDB数据库,包括PetDB的设计理念、使用方法和应用特色,旨在抛砖引玉,倡导基础数据的及时积累和整理,为建立自主的研究型数据库奠定基础,为迎接"大数据"时代的到来做好充分的准备。PetDB is one of the most important basic databases in earth science and marine science. It is also the flagship for seabed petrogeochemical databases, which benefits marine geologists. PetDB combines nearly all the data of rocks from ocean floor, including petrological, mineralogical and geochemical data for rocks, glass, minerals and inclusions. For geochemical data it often contains the major elements, trace elements and isotopic rati- os. The data in the database is integrated, well organized, easy for quiry and download. This quite popular and widely used database for petrology of ocean floor--PetDB, which can be treated as a BigData tool in petrology, including the ideas to design the database, use instructions as well as its features, is introduced to domestic colleagues. It is well hoped that more and more petrogeochemists will pay more attention to and take interest in the da- tabase construction and BigData analysis, which is quite helpful in discussing new issues and performing scientific research.
