GENETIC TYPES, GEOLOGICAL FEATURES AND PROSPECTING ORIENTATION OF IRON DEPOSITS IN EASTERN JILIN PROVINCE

With a basic analysis on the metallogenic geologic settings, the genetic types and geological features of each type of iron deposits in Eastern Jilin Province are studied. Five types of iron deposits are recognized, i.e. sedimentarymetamorphic type, magmatic type, contact metasomatic (skarn) type, sedimentary type and weathered leaching type. Combined with the new progress in geologic prospecting, it is concluded that the studied area satisfies the essential geologic requirements for the metallogenesis of iron deposits. The iron resources potential in the area is great.
