通过对钻井、测井、三维和二维地震资料的综合研究,将内蒙古银额盆地查干凹陷白垩系至新生界划分为2个一级层序、4个构造层序、6个超层序和11个层序。根据等时层序格架下各层序单元内部的沉积充填演化特征,建立了不同级次构造成因层序... 通过对钻井、测井、三维和二维地震资料的综合研究,将内蒙古银额盆地查干凹陷白垩系至新生界划分为2个一级层序、4个构造层序、6个超层序和11个层序。根据等时层序格架下各层序单元内部的沉积充填演化特征,建立了不同级次构造成因层序的构造-层序关系。在此基础上,结合构造应力机制研究和区域构造应力场演化,采用平衡剖面技术解析查干凹陷的构造-沉积史,将该凹陷的构造和沉积演化序列划分为4个一级构造-沉积演化阶段和若干二级、三级构造-沉积演化阶段,进而分析了各构造-沉积演化阶段的构造和沉积特征、凹陷原型的性质及成因机制。 展开更多

以塔里木盆地上泥盆统东河塘组为研究对象,通过野外剖面观测、钻井岩心观察、测井曲线解释,认为东河塘组是一个具有完整海侵至海退旋回的标准Ⅰ型层序,相当于3级海平面旋回的沉积地层。东河塘组由低位体系域(LST)、海侵体系域(TST)与高... 以塔里木盆地上泥盆统东河塘组为研究对象,通过野外剖面观测、钻井岩心观察、测井曲线解释,认为东河塘组是一个具有完整海侵至海退旋回的标准Ⅰ型层序,相当于3级海平面旋回的沉积地层。东河塘组由低位体系域(LST)、海侵体系域(TST)与高位体系域(HST)组成。低位体系域仅发育局部的河流沉积体系;海侵体系域主要为受潮汐控制的滨岸沉积体系,由一系列向上变浅和变细的准层序叠置成退积的准层序组;高位体系域主要发育以波浪作用为主的浪控滨岸沉积体系,由一系列向上变浅和变粗的准层序叠置成进积的准层序组。此外在盆地周缘发育冲积扇、冲积平原及扇三角洲沉积体系。 展开更多

通过对贵州修文—广西天峨地区早三叠世地层剖面测制和相序解析,并对其相的确定和划分。重点从各地层组的岩性组合、生物组合、顶底界线入手,进行综合对比研究,进而达到相区划分。得出研究区早三叠世早期广海陆棚沉积环境演化为碳酸盐... 通过对贵州修文—广西天峨地区早三叠世地层剖面测制和相序解析,并对其相的确定和划分。重点从各地层组的岩性组合、生物组合、顶底界线入手,进行综合对比研究,进而达到相区划分。得出研究区早三叠世早期广海陆棚沉积环境演化为碳酸盐缓坡沉积环境;末期向镶边碳酸盐台地沉积环境过渡,而罗甸板庚一带为孤立台地沉积环境。同时建立起研究区早三叠世两个三级层序。 展开更多

We are glad to know that our paper "Review of research in internal-wave and internal-tide deposits of China" (Gao et al., 2013) published in Journal of Palaeogeography has attracted close attention of international peers, and we noted that Shanmugam has provided a critical assessment of our paper. He claimed that "interpretations of ten ancient exam- ples in China and one in the central Appalachians (USA) as deep-water deposits of internal waves and internal tides are unsustainable", among many other comments and criticisms, and he concluded that "any interpretation of ancient strata as deposits of internal waves and internal tides is premature". This article is aimed at responding to his major criticisms. We believe that constructive discussions will benefit the development of the study in internal-wave and internal-tide deposits. Unfortunately, Shanmugam seems not to follow this line of scientific criticism, but is trying to reject all research results in this subject based on his illogical and inconsistent reasoning, and distortion of others' points of view. In this article, with facts and evidences, we will refuse the main wrong assertions of Shanmugam's, for example, "the use of bidirectional cross-bedding as evidence for deposition by baroclinic currents in outcrop studies is sedimentologically erroneous " and "any interpretation of ancient strata as deposits of internal waves and internal tides is premature". We will also use typical characteristics of the ancient examples to demonstrate that they are certainly not turbidites, or contourites, or tsunami-related deposits, but internal-wave and internal-tide deposits as the most plausible to defend the rationality of our interpretation in our previous papers. 展开更多
