This study recognized that original rocks of the felsic metamorphic rocks from a key horizon (termed K and K_S) in Guangchangling Archean Banded Iron Formation are tuffaceous intermediate acidic volcanic lava for biotite-quartz-albite gneiss (K) and tuffaceous sedimentary rock for garnet-mica-quartz schist (K_S) respectively.Therefore, K and K_S can not be the same horizon. According to this and some new stratigraphic sections, the stratigraphic section for Guangchangling Archean Banded Iron Formation was renewed....

This study recognized that original rocks of the felsic metamorphic rocks from a key horizon (termed K and K_S) in Guangchangling Archean Banded Iron Formation are tuffaceous intermediate acidic volcanic lava for biotite-quartz-albite gneiss (K) and tuffaceous sedimentary rock for garnet-mica-quartz schist (K_S) respectively.Therefore, K and K_S can not be the same horizon. According to this and some new stratigraphic sections, the stratigraphic section for Guangchangling Archean Banded Iron Formation was renewed. It suggests that this banded iron formation was developed in a shallow sea environment on a continental shelf and the iron ore beds are in mid-upper part of the transgressive series. The characteristics of sedimentary rock association of Guangchangling Banded Iron Formation are different from that of greenstone belt and similar to that of typical supracrustal rocks in high-grade terranes.

弓长岭太古代条带状硅铁建造中的长英质变质岩为该地层的标志层(K和K_S层)。原岩恢复表明二矿区黑云母石英钠长变粒岩(K层)为含火山灰的中酸性火山熔岩;而岭东区的石榴云母石英片岩(K_S层)为含火山灰的泥砂质沉积岩,二者不能对比。据此,本文补充和完善了该区地层剖面。它表明弓长岭硅铁建造生成于大陆边缘的陆棚浅海环境,其铁矿层赋存于一海进层序的中上部。该建造的沉积岩组合特征与绿岩带不同,而与典型的高级区表壳岩组合类似。

Reserach has revealed that there exists about 19.2m marine formation of Holocene in B_2 core of the Haihe delta.Form the bottom to the surface of the formation,it can be divided into six sedimental facies:intertidal-flat deposits,shallow marine deposits, prodelta deposits,delta bay deposits,river mouth bar deposits and river mouth-side flat deposits.The two facies in the lower part,near the bottom,showed transgressive se- quence and the others regressive sequence. The boundaries of these facies are discontinuity...

Reserach has revealed that there exists about 19.2m marine formation of Holocene in B_2 core of the Haihe delta.Form the bottom to the surface of the formation,it can be divided into six sedimental facies:intertidal-flat deposits,shallow marine deposits, prodelta deposits,delta bay deposits,river mouth bar deposits and river mouth-side flat deposits.The two facies in the lower part,near the bottom,showed transgressive se- quence and the others regressive sequence. The boundaries of these facies are discontinuity surfaces except the base of the river mouth-side fiat deposit.This shows that the Holocene marine formation is discontinu- ous deposit.Research shows that the discontinuous deposit is referable to sea-level change. The sea-level has continuously been in the state of osillation with an amplitide of approximately lm since the highest sea-level of Holocene passed.One oscillation wave can leave a chenier on the coastline.In the last 5000 odd years oscillation wares occurred five times,which resulted in five cheniers accumulated on the regression plain of the west coast of Bohai Bay. The discontinuity surfaces in the regressive sequence of B_2 core correspond to the erosion surfaces of chenier bases and rising phase of each sea level oscillation wave. From the research we can see that the coast deposits spreading towards the sea as shown in the regressive sequence of this area does not result from a large scale sea-level falling but rapid deposition in estuary area.

B_2孔揭示海河口地区全新世海侵层厚达19.2m,自下往上依次出现潮间滩、近岸浅海、前三角洲、三角洲湾、河口砂坝及河口边滩六个亚相,下部两个亚相呈海进层序,上部四个亚相呈海退层序。除河口边滩亚相底界外,其他所有亚相间的界面均为不连续面,显示海侵层为不连续沉积。研究表明该不连续沉积与海面波动有关.在全新世海侵高峰后,海面一直处于幅度不大(约1m 左右)的振荡运动状态,一次振荡波就在海岸线上留下一道贝壳堤,近5000余年来发生了5次振荡波,在海退平原中就有5道贝克堤与之对应。B_2孔海退层序中曲不连续面与贝壳堤基底侵蚀面相对应,也与振荡波的上升坡段相对应。海退层序所表现出来的海岸向海推进现象不是海面大幅度下降的反映,而主要是河口区沉积物迅速加积的结果。

Owing to the complexity of high-grade metamorphism,the divisions of Archean eon inthis area are in various opinions.On the basis of the protolith restoration,a new schema ofstratigraphic division was set up.It consists of Caozhuang Group of early Archean era(3600-3200 Ma),Qianxi Group of middle Archean era(3200-2800 Ma),Zunhua Group(2800-2450Ma)and Shuangshanzi Group and Zhuzhangzi Group(2650-2450 Ma)of late Archean er-a.According to the data of lithochemistry,microelement and rare earth element,the environ-ments...

由于高级变质区的复杂性,因此对区内太古字的划分众说纷坛。在恢复变质岩原岩的基础上,论证了新的地层及时代划分方案,包括古(早)太古代曹庄群(时限为3600~3200Ma)、中太古代迁西群(包括早期的下亚群水厂表壳岩,时限为3200~3000Ma及晚期的上亚群太平寨表壳岩,时限为3000~2800Ma)、新(晚)太古代早期的遵化群(2800~2650Ma)与晚期的双山子群(原滦县群,相当下亚群〕、朱丈子群(二者的时限为2650~2450Ma)。利用岩石化学、微量元素、稀土元素分析广太古宇的变火山岩系列,认为均属沟、弧盆的生成环境,曹庄群属于稳定单陆屑建造。生成于冒地槽环境(沉积第一阶段);迁西群至朱丈子群为非稳定型杂陆屑建造。参照听伴生的火山岩的地化成果,进一步划分中太古代属于岛内至岛前盆地的海进层序(第二沉积阶段)及新太占代各群白早而晚为孤前、孤内至孤后盆地的海退层序(第三沉积阶段)。
