Development And Application Of The Calculated Software Of Geochemical Processes Of Magma

The application of geochemical date indicating the magmatic processes, is now used in the dealing with the geochemical date of trace element. The Excel software, which was ever used in the calculation and mapping of geochemical date, can not meet the needs of the practical work because of the unfriendly interface, complex operation process and so on. Calculation software of the magmatic processes developed in the Windows platform, can be intuitive and friendly interface, enhanced data-processing functions, beauty date and simple operation, so analyzed samples and data management for the researchers has become a pleasant more effective and simple job. This system can be used for dealing with the analysis dates and mapping automatically, thus it saves the valuable time of geochemical workers as well as the human and material resources. This paper mainly describes that the application of the geochemical magmatic processing software developed by Delphi 7.0 in dealing with geochemical date of trace element and taking the Cenozoic basalts and peridotite xenoliths in Fangshan of Subei basin for an example test analysis of the REE of peridotite xenoliths. It demonstrates that peridotite xenoliths from Fangshan in Subei basin are formed from the basaltic phrase in the asthenosphere which underwent different degrees of partial melting. Spinel lherzolite is the mainly rock type of peridotite xenoliths from Fangshan in Subei Basin. Using the developed software to analyse the REE in the sample distribution of the model shows that the samples this study are mainly the residues (6%-22%) of asthenosphere material which occurred different degrees of partial melting in the spinel phase, melting degree of heterogeneity, but it doesn't exclude the garnet phase of small-scale partial melting; the simulated values of basalt melt obtained by simulating peridotite xenoliths is inconsistent with the REE distribution in the host basalts and it shows that the peridotite xenoliths and the host basalts aren't from the same source area, that is to say, the cause of host basalts in Subei basin doesn't couple in the peridotite xenoliths from Fangshan. The calculated results of spinel peridotite experienced non-residual solid phase melting, melt rate of F=0.15 and the REE of host basalts experienced small-scale mixing shows that the peridotite xenoliths might record the early stages of basalt metasomatism. In the actual calculation process, the trace element geochemical data-processing software can meet the basic requirements with a friendly interface and simple operation.
