山东省沿海岸带矿产资源分布特征

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（辽宁胶东半岛）成矿区和胶南威海成矿区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。

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

Mineral resources are widely distributed along the coastal zone in Shandong province with abun-dant reserves.Due to differences of crustal evolution,rock construction and ore beraing construction are different,thus,mineral resources distributed in each tectonic units have different characteristics.Rock se-ries formed in each geological history distributed certain minerals.Coastal zone in Shandong province be-longs to classⅠ metallogenic belt of the circum pacific.It belongs to three class Ⅱ metallogenic prov-inces,they are Jiyang metallogenic province（north China）,north Shandong （Liaoning Jiaodong peninsu-la）metallogenic province and Jiaonan weihai metallogenic province.Occurrence and development of re-gional metallogeny in Shandong province and the formation of ore deposits are controlled by the develop-ment and evolution of regional geology,thus,the distribution of minerals has the characteritics of hetero-geneity and regularity in time.
