Authors suggest that uranium ore formation occurred after the appearance of the above subsidiary tectonic units, and sandstone bodies of the Ⅱ,Ⅲ,Ⅳ,Ⅶ cycles, Shuixigou Group in the southern syncline, and sandstone bodies of the Ⅰ,Ⅱ,Ⅲ,Ⅴ cycles, Shuixigou Group, as well as sandstone bodies of Xiaoquangou Group in the northern monoclinal zone, they are ...

文章认为铀成矿作用发生在这些次级构造单元形成之后，且具有找矿前景的是南部向斜带水西沟群第Ⅱ、Ⅲ、Ⅴ、Ⅶ旋回砂体和北部单斜带水西沟群第Ⅰ、Ⅱ、Ⅲ、Ⅴ旋回砂体及小泉沟群砂体。从容矿层位连续性、分布面积、砂体特征及层间氧化带发育特征等成矿条件看，北部单斜带铀成矿条件和找矿前景均优于南部向斜带。

Based on a comprehensive study of drilling and log data, sequences of short-term base-level cycle of turbidite fan in Yanchang Formation of Triassic in Longdong area are divided into three basic structure types: up - deepening non - symmetry, up -shallowing non ?symmetry and symmetry ones according to recognition sign of the interface of the short - term base - level cycle.

以高分辨率层序地层学理论和技术方法为指导，以钻井、测井资料的综合研究为基础，运用短期基准面旋回界面的识别标志将陇东地区三叠系延长组浊积扇短期基准面旋回层序划分为向上"变深"非对称型、向上"变浅"非对称型和对称型3种基本结构类型。

Grain-size analysis and sedimentary structure observation show that different types of swamp deposit sections are characterized by pluvial-paludal deposit cycles, which includes a pluvial period and a paludal period.

粒度分析与沉积构造观察表明，华北平原不同类型沼泽沉积剖面都具有洪水-沼泽沉积旋回特征，每一个旋回对应一个洪水期和一个沼泽期。

Based on 14C dating of the top of paludal layers, it is confirmed that there are at least 10 cycles in the North China Plain during Holocene with the ending time as:（13000±140） aB.P.,（12910±180） aB.P.,（10530±120） aB.P.,（9500±40） aB.P.,（8760±250） aB.P.,（8030±150） aB.P.,（5600±85） aB.P.,（5020±200） aB.P.,（4600±190） aB.P., and （3470±125） aB.P.

以沼泽层层顶14C测年结果为划分沉积旋回的时代界限，华北平原全新世至少存在10个洪水-沼泽沉积旋回。

Dated from Proterozoic to Mesozoic, they have poly-circle characteristics, found from one tectonic circle to another, which is very rare in the worldwide orogens. This reveals that the orogen and stable area of the world, the mantle and crust states of the Proterozoic and Phanerozoic are different in tectonic evolvement and dynamic process and that the rapakivi granite of the Qinling-Kunlun is a kind of orogenic granite different from the stable area of the Proterozoic.

它们出现在每一个大的造山旋回晚期，即向另一个构造旋回的转折期，这在世界造山带中是十分罕见的，反映出世界上造山带与稳定区元古宙和显生宙的地慢与地壳状态是不一样的，有着不同的构造演化历史和动力学过程，表明秦岭－昆仑地区的环斑花岗岩是一种有别于元古宙稳定区的造山型环斑花岗岩。

The gigantic pillow lava, characterized by huge pillow bodies (5 to 8 m) and diverse shapes, constitutes a distinctive landscape of volcanic rocks.

辽西义县许家屯巨型枕状熔岩产在义县旋回第二亚旋回火山岩沉积夹层中。

Cyclostratigraphy was born in 1980s as a subdiscipline of stratigraphy. Based on the Milankovitch theory, outcrop sections and cores are analyzed with methods such as geochemistry, spectrum analysis, and time-sequence analysis to study the complex responses of orbital forcing to sedimentary records.

旋回地层学作为一门独立的地层分支学科诞生于20世纪80年代，它以米兰科维奇天文轨道旋回为理论基础，以露头剖面、岩心等为研究对象，应用地球化学、光谱分析和时间序列分析等方法，研究天文轨道参数周期性变化在地层记录中的沉积响应。
