    CHARACTERISTICS OF HUANGSONGDIANZI CONGLOMERATE TYPE OF GOLD PLACER IN HUICHUN CITY OF JILIN PROVICE

    • 摘要: 黄松甸子砾岩型金矿赋存于新第三系中新统土门子组底部砾岩中。为流水成因的古河道砂金矿,可见多层矿体,但以底部矿体最佳,呈条带状,沿走向和倾向都比较稳定,金粒以板状为主,多在0.25mm以上。该类矿床多分布在矿质来源丰富、沉积环境良好的地区。

       

      Abstract: Huangsongdianzi conglomerate type of gold deposit occured in conglomerate of the lower part of Miocene series Tumenzi formation. Mtiltilayer interparall orebodies cxisted in gold deposit, whereas the lower strata orebody is the best one. Orebodies are mostly banded and stabte in strike and dip.The high grade of gold is 2-4g/m3, the grain of it mostly tabular and more than 0.25mm in size, the degree of purity of it from 912.7 to 936.8.This type of deposit mostly distributed in the areas which are with richful mineral-coming, warm-humid paleoclimate、suitable hydroolynamic condition and favourable sedimentary environment, searching for conglomerate type of gold deposit in above areas can get twice the result with half the effort in exploration.
