Ore-forming Factors Analysis of Wengquangou Boron Iron Ore Field in Liaoning Province
The Wengquangou boron iron deposit is a known super large boron iron deposit in Liaodong area,with a cumulative proven B2O3 component of 21.85 million tons and an average B2O3 grade of 7.23％.The symbiotic iron ore reserves are 283.02 million tons,with an average TFe grade of 30.65％,and the solid boron ore reserves rank first in Asia.Later on,two medium-sized boron iron deposits,Majiaxigou and Yujialing,as well as three small-scale boron iron deposits,were successively discovered on its periphery.These mineral deposits are mainly composed of magnetite boromagnesian iron ore type and boromagnesian magnetite type,with the characteristics of iron and boron minerals coexisting,generally containing uranium,rich in magnesium,poor in calcium,and polysulfide.They are formed on the basis of volcanic sedimentary metamorphism,combined with metamorphic hydrothermal alteration.Based on the geological characteristics of the ore body,this study focuses on analyzing the ore-forming factors of the Wengquangou boron iron ore field and exploring its ore-forming model,providing new ideas for further exploration and prospecting in the area.
