There are lots of gold depsits oeeurred in Jiaobei distriet. Through studying the distribution of gold element in strata and granites, and the relationship between gold deposits and geotectonic evolution history etc., it has been shown that the gold deposits, wnich were formed in diwa stage, have two sources of ore-forming material. One is mantle source.the other is erustal source.
