Abstract:

Rayleigh distillation was introduced to modeling the metallogenic element enrichment process in the mafic-ultramafic intrusions outcropped in Panzhihua, Hongge, Baima, Taihe, etc. in the Panxi district, Sichuan Province, for their multi-scale nested rhythmic layering and iron concentration variation. Then, both their statistical and hypothetical models were constructed and their patterns were plotted to assess the mineral resources of iron, vanadium and titanium. Results show the similarity of the patterns of those in Panzhihua, Hongge, and Taihe, and for which the possible relation to their good crystallization differentiation in their originate magma and being favorable for ore bearing are suggested. On the other hand,  that in Baima is not consistent with the former possibly for its poor crystallization differentiation and poor ore bearing nature.

Key words: ore-forming process modeling, mineral resources, Rayleigh distillation, Fe-Ti-V oxide deposits, Panxi district
