近日,中国地质大学资源学院马奔奔副教授团队在国际顶级石油地质期刊《AAPG Bulletin》上刊发研究成果,研究成果主要揭示了深埋藏条件下致密砂岩储层水-岩相互作用过程、潜在成岩物质迁移方式及其成岩响应机制。
近日,资源学院博士生王雨轩在国际著名地质学期刊《GSA Bulletin》上刊发研究成果,研究成果主要揭示了重庆涪陵地区五峰-龙马溪组富有机质页岩的多尺度非均质性特征,探讨了富有机质页岩非均质的成因及其对页岩纳米孔隙体系的影响。
To ascertain factors controlling melt production along a typical distal, ‘hotspot-interacting’ mid-ocean ridge, we investigated the extent and distribution of both plume-related and plume-unrelated b...
Abstract: The purpose of this study was to characterize more fully the surface charge characteristics of the end-member smectite in illite-smectite (I-S) mixed-layer phases found previously in pelitic...
Abstract: Adsorption studies of aromatic hydrocarbons of various molecular sizes on organo-clays in aqueous solution were carried out for characterizing the surface heterogeneity of organo-clays. Benz...
Several soil and reference smectites and vermiculites and one reference illite were examined by high-resolution transmission electron microscopy (HRTEM) to decipher the nanostructure and layer charge ...
Water vapor adsorption isotherms were measured for samples of loessial soil clays modified by removing organic matter and Fe and Al compounds. The isotherms were analyzed by the exponential adsorption...
Abstract: The heterogeneity of sites for Ca→K exchange was examined by microcalorimetry in the <0.2-&micro;m fractions of some selected smectites. Six groups of sites, ranging in exothermic exchange e...
Measurements of the differential heats of K-Ca exchange are used to show that 6 groups of sites (ranging from −13.8 to −5.1 kJ/eq and with as many as 4 in any one sample) exist in kaolins ...
The broad charge heterogeneity typical of nearly all smectites is not necessarily characteristic of vermiculites. In addition to vermiculites with pronounced heterogeneity, minerals with no or only li...
Integrated intensities of the fundamental modes of vibrations of ammonium in heat-treated, NH4+-exchanged swelling minerals permits (1) a quantitative determination of the amount of tetrahedral substi...
Abstract: A comparison is made of the ion exchange behavior, towards the cobalt ion, of five sodium montmorillonite clays. The selectivity for the bivalent ion at low cobalt loading is correlated with...
A specimen montmorillonite (Arizona bentonite) was treated with hydroxy-aluminum solutions of various basicity. The cation exchange sites of this clay were found not to be homogeneous in their strengt...
