近期,中国地质大学资源学院王生维教授团队在岩石力学领域著名期刊《Rock Mechanics and Rock Engineering》上发表题为《Geometry and Filling Features of Hydraulic Fractures in Coalbed Methane Reservoirs based on Subsurface Observations》的研究成果。该文通过...
The hydrogen and oxygen isotopic characteristics of precipitation in coastal areas of Japan were explained on the basis of a long period (23 years) observation of hydrogen and oxygen isotopic ratios ...
The morphology of pore space has a strong effect on mechanical and transport properties of mudrocks and clay-rich fault gouge, but its characterization has been mostly indirect. We report on a study o...
Preliminary observations are presented concerning endoskeletal morphology in the Lower Carboniferous symmoriiform shark Denaea fournieri, and some problems in the original description are highlighted....
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...
Mineral dissolution experiments using batch cultures of soil and groundwater bacteria were monitored with solution chemistry and various microscopic techniques to determine the effects of these organi...
We report the direct experimental observation of a structural anomaly near 825 K insynthetic and natural titanite samples by high-temperature, hard-mode infrared spectros-copy. The anomaly in titanite...
TEispaperreports observations ofetched internal {OOO1}, {lOTO},{1120}, {loT1},and {1121} surfaces of Durango apatite. Three types of surfaces are distinguished: Ptype, S type, and T type. After initia...
Abstract: TEM characterization of stacking relations in I/S of expanded shale samples from the Gulf Coast and Michigan Basin was carried out to address the issues of the degree of coherency and the na...
Specimens ofdense high-pressure hydrous magnesium silicates, notably phase A,phase B,and superhydrous phase B,have been synthesized for use in calorimetric and spectro-scopic experiments. X-ray diffra...
Abstract: A process for treating smectite-bearing rock samples that utilizes LR White resin; allows TEM observation of expanded smectite interlayers and therefore preservation of original rock texture...
Transmission electron microscopy (TEM), including selected area electron diffraction (SAED), has been used to identify polytypes in illite, phengite and muscovite from samples representing a wide rang...
Abstract: Treatment of smectite with laurylamine hydrochloride was verified to cause expansion of d(001) which may be retained and observed in ion-milled samples by transmission electron microscopy. T...
The equilibrium diagrams developed for Al-hydroxide and for kaolinite by Garrels and Christ (1965) have been modified by taking into account the existence of gels. From the stability zones obtained, t...
Electron optical observations on Marblehead illite showed the presence of twinned aggregates of lath-shaped crystallites. The selected area diffraction patterns of these aggregates indicate a strict o...
