Quaternary folding in the south piedmont of central segment of Tianshan Mountains

The Tianshan Mountains are an important active structural belt in the interior of Eurasia. By integrated methods of surface geology survey and interpretation of seismic profiles, we distinguish fold scarps located at the south limb of the Kuqatawu anticline and the north limb of the Dongqiulitag anticline in the Kuqa rejuvenation foreland thrust belt, south piedmont of central segment of the Tianshan Mountains. Fold scarp is a newly found structural phenomenon. Because of the bend of thrust plane and the movement of hanging wall above the thrust plane, the original horizontal deposits of hanging wall and their surface become a monocline structure, resulting from the separating and migration of the active and fixed axial surfaces. Measuring the geometry of fold scarp and using the data of age of the deformed deposits, the crustal shortening rate resulting from the deeply seated subsurface thrust is calculated. The crustal shortening rate reflected by the fold scarp located at the north limb of the Dngqiulitag anticline is (1±0.1) mm/a. The fold scarps of the Dongqiulitag anticline and the Kuqatawu anticline identify that the deformation process of the crustal compressive structures in the Kuqa area extends into the Late Quaternary.     

郯庐断裂带鲁南段新元古界石旺庄组的震积岩序列

在郯庐断裂带鲁南段新元古界石旺庄组碳酸盐岩地层中,鉴别出一套震积岩,其主要类型为液化方解石脉、同沉积褶曲、震碎角砾岩、海啸岩等。经过分析,这些现象是地震作用形成的震积岩—啸积岩序列,该序列为地震原地相和海啸异地相震积层组成的双层结构,两层之间被震积不整合面所分隔,因而为鲁西新元古界的地层对比增添了新的材料。     

Discovery of deep-level foreland thrust-fold structures in Taihang Mt. and its implication for early tectonic evolution of North China

Delineation and correlation of Dragon Spring Shear Zone with its deep-level structures at foreland have been studied by field work. This paper reports our new findings of thrust-fold structures within Taihang Neoarchean basement, which include flat thrusts,large-scale recumbent folds, subhorizontal foliation patterns, etc. It reveals that early tectonic evolution of North China clearly involves the horizontal contraction on a large scale, comparable to those of foreland of classical collisional orogenic belts. The vertical variation of structural patterns with foreland fold-thrust belt from shallow to deep levels has been documented for Taihang Mt. by structural correlation,which is associated with tectonic transposition and imbrication of basement complex with supracrustal sequences in the Neoarchean.     

淮北宿临矿区构造特征及演化

宿临矿区是淮北煤田的主要赋煤地带。自石炭二叠纪以来，该区经受了多次构造活动。在早期形成的徐准拗陷基础上主要发育有东西向及北北东向的断裂，这些断理解共同构成了矿区的基本构造格架。断块内褶皱多为开阔短轴褶皱，并发育有较大一级的北东向断层有层滑构造等。岩浆岩的侵入明显受断裂构造控制。矿区内地球物理场特征（场值及分布）也正证实了矿区内构造展布及演化的综合特征。而这种构造演化与华北板块南缘和东缘的两条板缘构造活动带密切相关。

太湖穹窿中逆－逆冲断层及外围的推覆构造

太湖穹窿中逆－逆冲断层均发育在褶皱的翼部，并在平面上成放射状排列。而推覆构造为浅成的、弧立的飞来峰散布在穹窿的外围．通过几何学、运动学的研究，揭示这些构造与太湖穹窿在成因上有密切联系．即当垂直构造力向上顶托形成隆起时，岩层沿下震旦统软弱层发生垂直半径方向的收缩，产生侧向挤压，形成穹窿褶边褶皱，并在褶皱陡翼产生逆－逆冲断层，组合成放射状构造。而在穹窿的中心顶部出现正断层，受正断层切割的顶部地层失去相互牵制力，在重力作用下发生向四周滑动，形成散布在穹窿外围的推覆体。穹窿顶部成为构造剥蚀区，其缺失的地层与推覆体相对应．因此逆断层、逆冲断层、推覆构造、褶边褶皱是形成太湖穹窿时，同一构造力作用的产物，并组成统一的构造系统。
