| Abstract: | The chromite deposit located in Luobusha ultramafite in Tibet is the largest one around China. The concealed deposit prediction method presented in this paper has following features: (1) it is run through by the study of tectonics directly controlling the formation and emplacement of deposit; 2.the structural analpsis, quantitative mineralogy and mathematical geology and other methods are used simultaneously; 3.various geophysical information is best processed and then applied as possibly as it can be; 4. the basis of the study of ore-forming conditions,ore-controlling geological factors, oreforming regularity and ore-hunting indicators, the ore-bearing property of ultramafite was evaluated. At last, the prospecting targets have been delineated and the mineral resource quantity of chromite is also assessed. |
