METALLOGENIC CHARACTERISTICS AND REGULARITIES OF TIN DEPOSITS IN QINGHAI PROVINCE

Tin is one of the non-ferrous metal minerals with great prospecting potential in Qinghai Province. The ore-forming ages are relatively concentrated, mainly in Indosinian and Hercynian. The tin deposits and occurrences, dominated by skarn type, are mainly distributed in the East Kunlun metallogenic belt. Combined with previous researches and geological data, the paper discusses the metallogenic geological background, general resources situation, genetic types of deposit, ore-controlling factors, metallogenic age and division of tin metallogenic belts, summarizes the metallogenic characteristics and regularities, and puts forward suggestions for further exploration of tin ores in Qinghai Province.
