2018年11月,国际石油地质重要期刊《AAPG Bulletin》刊发了中国地质大学关于中国东部渤海湾盆地断陷湖盆浅水三角洲发育特征的研究成果,并且野外露头照片被设置为本期封面。论文第一作者为资源学院构造与油气资源教育部重点实验室黄传炎高级工程师,共同作者分别为资源学院王华教授,东方地球物理公司涿州分院张宏伟,华北油田研究院吴健平,资源学院刘英杰。
The dramatic, dinosaur-to-bird transition that occurred in reptiles millions of years ago was accompanied by profound changes in the skull roof of those animals — and holds important clues about the w...
The ophiolitic remnants of the Upper Mesozoic Rocas Verdes basin in southernmost South America were studied from the perspectives of petrography, chemistry of minerals, bulk-rock geochemistry, and U–...
Small-scale isolated carbonate mounds situated on a smoothly inclined homoclinal ramp characterized the initial phase and acted as nuclei of further carbonate buildup growth. However, only the ideal p...
The Ankara section of the İzmir-Ankara-Erzincan Suture Zone (IAESZ) is characterized by two major groups of contractional structures, namely the Ankara forced folds-monoclines and the southward-...
A detailed ichnological analysis, for the first time, has been preformed on Upper Eocene-Lower Oligocene Transition of Manipur, Indo-Myanmar Ranges (Northeast India). Previous trace fossil analyses in...
In October of 2003 a fleet of autonomous underwater gliders began a time series of transects across the New Jersey shelf. The gliders are equipped with a conductivity-temperature-depth sensor, and som...
Biological C-sequestration includes a series of well-known techniques to help meeting the requirements of the Kyoto protocol : various biological methods (trees, agriculture etc.) have been debated in...
Abstract: Development of preferred orientations of illite-smectite (I-S) has been studied using X-ray diffraction (XRD) texture goniometry to produce pole figures for clay minerals of a suite of 16 mu...

Diffuse X-ray scattering from single crystals of metamict zircon reveals residual crystallinity18 ?-decay events/g). The experimental evidence does not sug- even at high fluences (up to 7.2 ? 10 g...
Clay mineralogical X-ray diffraction and electron microprobe studies have been carried out on separated <2 ?m fractions from cutting and core material from three wells in the Chipilapa geother- mal ...

Within the framework of the Adam-Gibbs (configurational entropy) theory of viscosity,it is shown that for a given composition, the ratio of parameters Be (a temperature inde-pendent constant) to Sc( ...
The structural changes associated with the C 2/ m - P 21/ m phase transition in cumming-tonite with (Fe 1 Mn)/(Fe1 Mn1 Mg) ┆ 0.50 have been studied with single-crystal X-ray diffraction at various pre...
The effect of water (5 H2O 1 OH) on the environment of Co21and Ni21 in albite glass was investigated by electronic absorption spectroscopy. The visible spectra of Co21-doped glasses change only slight...
