These data are incompatible with the excursion scenario unless (1) carbonates deposited during a negative δ13C excursion are more susceptible to later δ18O metamorphic alteration in proportion to their negative δ13C value, or (2)δ18O of sea water decreases as δ13C of sea water decreases to produce an array that fortuitously resembles the Cenozoic lithification domain Fig.

这些数据与想象的同位素漂移情况不一致，有两个因素应当考虑在内。1。碳酸盐在δ13C存在负值漂移时沉积更加容易受到后期δ18O变质交代作用的影响，这种影响与δ13C成比例。2。海水δ18O与δ13C的同步减少使得数据出现在图表上的近似新生代成岩作用区域，这种情况属于偶然情况。

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。

The influential factors are: horizon, different system in strata sequence framework, clast composition, structure, matrix quality in source area, sedimentary facies belt, diagenesis, volcanics distribution and pressure distribution.

There are three evolution paths for the kaolinitic rocks in the diagenesis:one is that kaolinite is transformed to the mixed minerial of kaolinite/dickite and dickite in the acid environment; the second is to be trnasformed to the ammonium illite,chlorite and pyrophyllite in alkaline environment;The third is to be transformed to well ordered kaolinite in the superfacial environment. The highly orderization of kaolinite may be related to the hot solution underground.

提出煤系高岭岩三种成岩演化轨迹；一种是在酸性环境下朝高岭石/地开石间层矿物和地开石方面演化；另一种是在碱性环境中朝氨伊利石、绿泥石和叶腊石方向演化；第三种是在表生环境种朝高度有序高岭石方向演化，高岭石的高度有序化可能与热水溶液作用有关。

Based on the seal mechanism, the sealing conditions of the three migration pathways are analyzed in this paper: the seal on a fault rock zone without adhesive power is dependant on the content of fault mud; the seal of an associated fracture inside a crushed zone is dependant on the relationship between the section pressure and fragile strength of the fault gouge; the seal quality of an induced fracture zone is controlled by the quantity of later rock-forming fill.

基于这种封闭机理，分析了3种通道封闭的条件：无粘结力断层岩带是否封闭取决于断层泥含量大小；破碎带内部伴生裂缝的封闭性取决于断面压力和断层泥塑性强度关系；诱导裂缝带封闭程度受控于后期成岩充填的程度。
