山东省沿海岸带矿产资源分布特征

Distribution Characteristics of Mineral Resources Along the Coastal Zone in Shandong Province

摘要:

山东省沿海岸带矿产资源分布广泛，资源储量丰富。由于地壳演化历程的差异，决定其岩石建造和含矿建造的差异，从而导致了各大地构造单元内分布着各具特色的矿产；各个地质历史时期中形成的岩系都分布着一定的矿产。山东省沿海岸带属环太平洋Ⅰ级成矿带，分属于济阳(华北)成矿区、胶北(辽宁[CD*2]胶东半岛)成矿区和胶南[CD*2]威海成矿区3个Ⅱ级成矿区。由于山东省区域成矿作用的发生、发展和矿床的形成都受区域地质的发展演化控制，矿产在时间上的分布具有不均一性和规律性。

Abstract:

Mineral resources are widely distributed along the coastal zone in Shandong province with abundant reserves. Due to differences of crustal evolution, rock construction and oreberaing construction are different, thus, mineral resources distributed in each tectonic units have different characteristics. Rock series formed in each geological history distributed certain minerals. Coastal zone in Shandong province belongs to classⅠ metallogenic belt of the circumpacific. It belongs to three class Ⅱ metallogenic provinces, they are Jiyang metallogenic province(north China), north Shandong (LiaoningJiaodong peninsula) metallogenic province and Jiaonanweihai metallogenic province. Occurrence and development of regional metallogeny in Shandong province and the formation of ore deposits are controlled by the development and evolution of regional geology, thus, the distribution of minerals has the characteritics of heterogeneity and regularity in time.
