摘要：

根据南极火成岩信息和数据类型多、数据关系复杂、样品间数据完整性和精度差异大的特点，中国南极火成岩数据库划分为主库、来源文献、岩体地质学、岩石学、主要氧化物、稀土元素、痕量元素和同位素８个数据库。通过岩体系统号、样品系统号和来源文献号三个字段使８个数据库相互关联。中国南极火成岩数据库包括了１４０多个基本字段，存储火成岩岩石描述信息和分析数据。根据国内外火成岩数据标准化的现状的分析，中国南极火成岩数据库采用了国际地科联岩石学数据库分委会规定的标准词汇和代码，并利用代码－名词术语转换技术改善了用户界面

Abstract:

The information and data of Antarctica are characteristics by the fact that the types of data are numerous, the relations between them are complicated and very different in completeness and in accuracy.According to these characteristics,China igneous rock database of Antarctica will consist of eight files,i.e.main,source,geology,petrology,essential oxide,REE,trace elements and isotopic files. The eight files will be associated with three fields which are system numbers of rock body,sample and source.China igneous database of Antarctica includes more than 140 fields in which the descriptive information and analytical data of igneous rock are stored. Taking into account of present condition of standardization of igneous rock data,the standard vocabulary and codes from IUGS Subcommission on Data Base for Petrology will be used.
