The Geology And Geophysical And Geochemical Characteristics And Ore Finding Sign In Daxing’anling Lead And Zinc Deposit

In order to speed up the da hinggan mountains in heilongjiang province HuZhong area next ga to Mr Iraqriver upstream lead-zinc polymetallic mine mineral resources exploration and development pace, furtherimprove the ore control degree and research level, for mine exploitation planning provides the basis, thispaper mainly studies the regional geology and mine geological characteristics, the application ofgeophysical comprehensive exploration means on I number, Ⅱ number and Ⅳ number ore zone ingeological research.After the research achievements are as follows:1through this mineral exploration work, find out mining stratum, structure, magmatic rock andmetamorphic rock characteristics and distribution; Find out the basic mining deposit characteristics,lead-zinc resource and associated silver resources distribution and output rule.2ascertain the main roughly the number of ore body, shape, scale, occurrence characteristics, orestructure, structure, mineral composition and useful chemical composition of the content, and thepreliminary understanding its occurrence state and change. Generally find out main orebody in clamp stonelithology, occurrence and morphological changes.3discovery and delineation of lead-zinc body article35, iron ore body article19, molybdenum ore bodyarticle19. According to the metallogenic geological background characteristics, combined with theore-controlling factors and metallogenic conditions, mineral combination, preliminary think deposit originbelongs to skarn type deposit. Ore body in production along the granitic rock intrusion and marble contactwith internal and external or leave the rock mass along the marble rock in the skarn. Skarn are calcareousskarn class, rock type to garnet skarn, garnet diopside skarn, diopside garnet skarn, diopside skarn is givenpriority to, occasionally saw a wollastonite skarn.
