摘要
永和磷矿的磷质主要来自南华洋前湘锰期的海底火山活动 ,上升洋流是磷质运移的主要营力。根据本区的 2个冰海—含磷建造的旋回组合特征 ,本文提出了“冰期磷质储集库”的新解说 ,揭示了“大冰期成磷说”的内涵机理。
P matter of Yonghe P deposit mainly comes from submarine volcanic activity of preceding Xiangmeng age in South China ocean, upwelling oceanic current is main agent of P matter migration Depond on the two circles association characteristics of glaciomarine P-bearing sedimentary suite, this paper puts forwards the new explain of P matter store in ice age, and reveals the substance of great Ice Age phoshorus genisis
