“…They also played a key role as catalysts in the genesis of petroleum from organic matter generated from living organisms, this time following a top‐down process. As above indicated, clay minerals help concentrate organic matter by adsorption, leading to organoclay complexes that subsequently may play a catalytic activity, in this case to generate oil and gas . The direct involvement of clays in the interaction and further transformation of dispersed organic matter promote the formation of liquid and gaseous hydrocarbons at moderate temperatures …”

The rise of organic-inorganic hybrid materials in both academia and industry results from a convergence of diverse expertise and communities and is driven by the curiosity of open-minded scientists. In this review article, a historical perception on the evolution of hybrid material science is described. The major periods associated with the genesis of hybrid materials are discussed: prebiotic hybrid chemistry, hybrid materials made through know-how, the rise of silicates and silicon chemistry, modern hybrids: a mushrooming multidisciplinary field of research, and current applications of hybrid materials fully integrated in the society. Finally, the review presents an outlook that summarizes some future prospects related to hybrid materials.

“…Kaolinite, montmorillonite, illite, and chlorite are the most common clay minerals which are ubiquitously found in the subsurface environment (Wilson et al 2014). Other clay types are those composed of a mixture of these four clays (Jiang 2012). Clay particles have a high potential to interact with other (bio) colloids and could serve as carriers of colloids due to their surface charge heterogeneity (Schroth and Sposito 1997;Vasiliadou and Chrysikopoulos 2011;Syngouna and Chrysikopoulos 2013;Cai et al 2014).…”

Utilization of nanoparticles (NPs) for a broad range of applications has caused considerable quantities of these materials to be released into the environment. Issues of how and where the NPs are distributed into the subsurface aquatic environments are questions for those in environmental engineering. This study investigated the influence of three abundant clay minerals namely kaolinite, montmorillonite, and illite in the subsurface natural aquatic systems on the transport and retention of aluminum oxide (Al 2 O 3 , 40 nm) and titanium dioxide (TiO 2 , 10-30 nm) NPs through saturated limestone porous media. The clay concentrations in porous media were set at 2 and 4 vol% of the holder capacity. Breakthrough curves in the columns outlets were measured using a UV-Vis spectrophotometer. It was found that the maximum NPs recoveries were obtained when there was no clay particle in the porous medium. On the other hand, increase in concentration of clay particles has resulted in the NPs recoveries being significantly declined. Due to fibrous structure of illite, it was found to be more effective for NPs retention in comparison to montmorillonite and kaolinite. Overall, the position of clay particles in the porous media pores and their morphologies were found to be two main reasons for increase of NPs retention in porous media.

“…Mixed layer clays exist here as a geothermometer and indicator of thermal maturity based on the concept first applied in detailed studies of the Gulf Coast (Hoffman & Hower, 1979). The transformation of clay minerals during diagenesis is from montmorillonite to mixed -layer smectite/ illite to illite (Jiang, 2012). During early diagenesis, maturity of the source rock is relatively low and smectite favors the percentage of illite-smectite mixed layer clays.…”

The Belaga Formation is a deep marine turbidite interpreted in relation to a submarine fan and therefore a prospect worth evaluating. The scope of this paper will focus on the shales from the thick sedimentary sequence of the Belaga Formation (Upper Cretaceous to Eocene) consisting of five (5) members in Central Sarawak, Malaysia, of which attention is given to the depositional environment and clay minerals as factors to consider as predictive tools for organic matter richness and gas storage capacity using the spectral gamma ray method using Thorium (Th), Potassium (K) and Uranium (U) as indices for inferences. A mineralogical chart of Th/K (ppm/%) indicates that the dominating clay minerals of the shales are mixed-layer types. The Th/U as a redox indicator is used to assert that the shales are of anoxic conditions of deep-marine environments. Despite the relatively high insoluble Th values (9.93-20.13) ppm, the presence of U in substantial amounts, which only occurs in reducing conditions where it is preserved as a lower insoluble valence (U 4+) explains for the low Th/U values ranging between (1.86-4.57) ppm/ppm of the fifty-eight analyzed shale samples. The overall Th/U value of the evaluated shales remain less than 7, where Th/U < 7 is suggestive of marine sediments, grey and green shales, whereas Th/U < 2 is indicative of marine black shales of reducing conditions. The 30Ma interval of sediment deposition of the Belaga Formation Eocene recorded varied climatic fluctuations influential to clay minerals contained in the shales and ascribe the paleoweathering state of the shales, which from the standard imitative ternary plot of normalized K-U-Th of shales from Northern America address the shales of the Belaga Formation as of deep weathering residuum.
