DEVELOPMENT OF A DATABASE ON EXPERIMENTAL CRYSTAL-MELT EQUILIBRIA FORIGNEOUS ROCKS - INFOREX-SYSTEM, VERSION-3.0

We present the INFOREX system, which is a base of experimental data on crystal-melt equilibria of igneous rocks, and the INFOREX-3.0 data-ma nagement system. This system is designed for use in petrologic and geo chemical investigations to provide fast access to experimental data an d makes it possible to customize data output based on chemical criteri a and the experimental conditions. The database includes 6174 experime nts from 162 studies and 8311 compositions of coexisting phases. The t ables of experimental conditions and the composition of run products a re stored in ASCII files with fixed width fields. The main options of the INFOREX-3.0 system allow one to customize the system to work with a certain set of minerals and rocks; obtain information on the current state of the database; view, edit, and add the results of an experime ntal study; select experiments corresponding to the defined range of i ntensive parameters and minerals associations; and calculate and test geothermometers for mineral-melt equilibria. The INFOREX system can gr eatly enhance the efficiency of petrological and geochemical investiga tions and is recommended for professional petrologists as well as for university students studying geology-related fields.
