    DISCUSSION ON THE RELATIONSHIP BETWEEN THE EVOLUTION OF DONGGOU COASTAL PLAIN AND PLACER GOLD IN LIAONING PROVINCE

      摘要
    • 摘要: 辽东半岛自晚白垩世以来，长期处于抬升剥蚀阶段，地形向准平原化，自晚更新世起发生多次海侵、海退作用，在黄海沿岸形成断续的滨海平原；数个滨海平原中以东沟滨海平原准平原化最好。其第四纪沉积物最全，厚度大，砂金成矿条件最好，对辽东半岛黄海沿岸砂金的供源条件、成矿环境的研究，并与国外特大型滨海砂金矿床的成矿地质条件对比认为，东沟滨海平原具有形成大型特大型滨海砂金矿床的成矿地质条件，此外，东沟平原从丘陵到浅海具有沟谷砂金、河床砂金、滨海砂金、浅海砂金的成矿条件，砂金潜在远景较大。

       

      Abstract: After late Cretaceous, Liaodong peninsula was elevated and denudated,and gradually peneplaned.Since late Holocene,repeated transgressions and regressions have resulted in some intermittent coastal plains along Yellow Sea,Among them,the Donggou coastal plain is the best peneplaned with well developed Quarternary deposits of large thickness and the best mineralization condition of placer gold.
