| Multi-info metallogenic prognosis, as an efficient tool for ore prospecting, represents a modern trend in deposit assessment worldwide. The system, aiming at metallogenic prognosis, is directed by metallogenic principle, supported by geological, geochemical and remote sensing principleson the corresponding anomalies, by mathematical measures and computing techniques to quantitatively analyse all data relevant to ore deposit from all concerning anomalies. The key of the study lies on the analysis on and utilization of geological, geochemical, geophysical data and tectonic prognosis variables in the area of interest, using the Mineral Resources Assessing System (MRAS), to rank the metallogenic favorableness of the potential variables for the formation of oredeposits. A prospecting model is set up based on the analysis in various kinds of data in the area, and on the metallogenic laws drawn from the existing deposit, its controlling factors and indicators for deposit. The metallogenic prognosis for East Kunlun region is integratedly conducted at a scale of 1:500,000, and the metallogenic favorableness distribution pattern is derived for Sedex-style deposit, with the outline of targeting areas, thus offering valuable clews for deposit prospecting in the region. |
