山东省滨海砂矿成矿规律及远景区划

Littoral Placers Forming Rule and Prospecting Divisions in Shandong Province

山东省滨海砂矿以石英、锆英石、磁铁矿、砂金等为主 ,其次为贝壳、球石、钛铁矿、金红石等。矿床主要分布在长期上升的胶北、胶南隆起的滨海地带。砂矿的分布与滨海带的基岩性质、海岸带类型、地貌、水系、水动力条件、海底底质等密切相关。根据成矿条件 ,可划分为7个成矿远景区。石英砂矿在全区分布较广泛 ,砂金在北部沿海成矿条件较好 ,锆英石。

Quartz, zircon, magnetite, gold are major constituents of littoral placers in Shandong province, while shell, ballstone, ilmenite, rutile being secondary. The placers mainly distribute in littoral zones of Jiaobei and Jiaonan lifts. The distributions have a close relation with bed rock property, littoral zone types, geography, water systems, hydraulic conditions and bed property of sea bottom. According to placers forming condition, 7 placers forming future areas have been divided. Quartz placers distribute widely in all areas; gold in north of littoral areas; zircon and magnetite in east and north areas.
