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.
