查询词典 sediments

Base on above studies, some conclusions were obtained as follows:(1) ore-forming background of the studied ferromanganese crusts are mainly controlled by intensity of Antarctic Bottom Waters and variations of material source;(2) it is confirmed that the ferromanganese crusts are mainly hydrogenetic and their composition are affected by volcanic and continental material simultaneously; there are no obvious phosphatization reconstruction and element reaction occurred in them, so they have important paleoceanological significance;(3) from researches on element occurrence modes in the new-type ferromanganese crusts and the lying sediments, it is proposed that there is no great biological affection on the crusts formation and their composition mainly came from the adsorptive action of the ferromanganese oxides in them;(4) two major types of ore-controlling factors are identified through compilation of ore-controlling factors, which are geological and oceanic factors;(5) considering the long-term variation trends of the crusts composition, combing the U-series and 10Be isotope dating results, it is proposed that the ore-forming processes of ferromanganese crusts in the studied areas can be divided into three major stages (5.6~2.8 Ma, 2.8~2.7 Ma and since 2.7 Ma), and then the activities of AABW since the Late Miocene, changes of input flux coming from volcanic and continental material are confirmed.

通过研究，得出如下结论：(1)研究区铁锰结壳的成矿背景主要受控于南极底流强弱及物源供给的变化；(2)证实铁锰结壳主要为水成成因，同时其物质组成也受一定程度的火山和陆源物质的影响；结壳自形成以来没有遭受到明显的磷酸盐化等成岩后期改造和元素再迁移，具有重要的古海洋学意义；(3)通过新型铁锰结壳及下伏沉积物元素赋存状态的研究，认为生物作用对研究区结壳的形成并没有很大的直接影响，其物质成分主要来自于结壳中铁锰氧化物的吸附作用；(4)在控矿要素的研究中，归纳出了地质与海洋两大类结壳控矿要素；(5)根据结壳成分长周期变化趋势，结合铀系和10Be测年结果，将研究区结壳的形成过程划分为三个主要阶段(5.6~2.8 Ma，2.8~2.7 Ma和2.7 Ma以来)，并确定了晚中新世以来研究区南极底流的活动情况、火山和大陆来源物质输入量的变化。
