Hannorpa Basalts, located at the north of Zhangjiakou,Hebei Province consist of two kinds of basalts of different chemical compositions. These, two kinds of basalts are interbeded and closely associated with each other, and thus give rise to a lithological cycle marked by regular variation in compositions. The characteristic values and the types of distribution of the rare earth elements in both two kinds of basalts show different features but possess a regular variation. They are all the partly melted products...

Hannorpa Basalts, located at the north of Zhangjiakou,Hebei Province consist of two kinds of basalts of different chemical compositions. These, two kinds of basalts are interbeded and closely associated with each other, and thus give rise to a lithological cycle marked by regular variation in compositions. The characteristic values and the types of distribution of the rare earth elements in both two kinds of basalts show different features but possess a regular variation. They are all the partly melted products of upper mantle materials. The calculation with the formula of part-melting quantitative model suggests that the alkaline basalts and the tholeiitic basalts are the lower grade partly melted products of garnet iherzolite (the lower level)and spinel iherzolite (the overling level) respectively in the upper mantle.

位于中国河北省张家口以北的汉诺坝玄武岩,由两类岩性不同的玄武岩组成,它们相间成层、相伴互生,构成变化规律的岩性旋回。两类岩石的一系列稀土元素特征数值和分配型式都表现出既不相同又有变化规律的特征。它们都是上地幔物质部分熔融的产物,据部分熔融定量模式计算认为,本区碱性系列玄武岩和拉斑系列玄武岩分别是上地幔处于不同部位的,既较深处的榴石二辉橄榄岩和其上部的铬尖晶石二辉橄榄岩的低度熔融的产物。

Block Shu 103 buried hill of the western depression in Liaohe oilfield consists of Gaoyuzhuang formation, Changcheng (Great Wall) system,middle Proterozoic erathemIts sedimentary environments belong to a carbonate peritidal zone Well logging data and seismic profiles show that internal strata of the buried hill have two distinct sedimentary cyclic sequencesFrom drilling cores,it is deduced that these cycles are composed of micrite,laminate stromatolite, conophyton or thrombolite dolomites,formed under the different dynamic conditions and with various levels of texture, structure and porositySome rocks,such as conophyton and thrombolite dolomites, are the products in mediumhigh energy zones, with coarse texture,well developed primary porosity, pore filled later and better solution openings and caves for dissolution, the others belong to the products in lower energy zones with worse porosity and texturesThe cyclic variation in petrology, and the difference in weathering and dissolution at various positions may affect production capability of oil wells

辽河西部凹陷曙103块潜山由中元古界长城系高于庄组组成,其沉积环境属碳酸盐岩台地潮缘,测井资料和地震剖面均显示出潜山内幕具两个明显的旋回层序。根据钻井岩心资料推断,这些旋回的岩性组合是:泥晶白云岩、层状叠层石白云岩、锥状叠层石白云岩或凝块石白云岩,它们分别形成于不同的水动力条件,因此其岩石结构、构造及孔隙发育程度都不尽相同。锥状、凝块石白云岩等属于中高能带的产物,结构粗,原生孔隙发育,后期多充填,在此基础上经溶蚀形成较发育的溶蚀孔洞;而其余岩类均为低能带产物,孔隙、裂缝不甚发育。这种岩性的旋回性变化与潜山各部位风化溶蚀程度的差异,直接影响各油井的产能

The carbonate ramp, characterized by the wide sedimentary facies, is short of visual physical markers of the sequence surface. But the multi scale lithological cycles caused by the fluctuation of regional climate sea level are well developed, which are strong in regional correlation and abundant in fossils.

The carbonate ramp, characterized by the wide sedimentary facies, is short of visual physical markers of the sequence surface. But the multi scale lithological cycles caused by the fluctuation of regional climate sea level are well developed, which are strong in regional correlation and abundant in fossils. Therefore, the regional outcrop sequence stratigraphy can be well studied in the light of the application of cyclostratigraphy and ecostratigraphy. The stacking patterns of the lithological cycles, i.e. parasequences, and the migration of the habitat types show that the Lower Triassic sequences are properly identified, on the outcrops in the Lower Yangtze region, for the establishment of the sequence stratigraphic framework. In addition, the transgressive surface can be used to define the third order sequences in the outcrop sequence stratigraphy on carbonate ramp, which are more understandable and practical.

碳酸盐缓坡区沉积相带宽 ,缺乏直观的物理层序界面标志 ,但区域上受气候海平面控制的多级岩性旋回发育 ,可对比性强 ,生物丰富 ,因而可借助于旋回地层学和生态地层学方法进行区域露头层序地层研究 .通过岩性旋回叠加型式和生境型迁移过程研究 ,较好地进行了下扬子区下三叠统露头层序划分 ,建立了层序地层格架 ,并提出以海侵面为界进行层序划分对于碳酸盐缓坡区露头层序地层研究更有可操作性和实用性
