Inorganic Geochemical Study of the Siliciclastic Sediments penetrated by Ash-3 Well in the Greater Ughelli Depobelt, Niger Delta Basin, Nigeria by K. Itiowe, B. Kpege, O.N. Ekone, O.J. Aliu

“…Using Herron’s plot for classification shows that the siliciclastic sediments were classified into Fe-shale, Fe-sand and quartz arenites fields. Roser and Korsch’s discriminant function diagrams for provenance signature and tectonic setting show quartzose sedimentary provenance and passive margin tectonic setting fields respectively. …”

Fractal Characteristics of Pore Structure of Longmaxi Shales with Different Burial Depths in Southern Sichuan and Its Geological Significance by Manping Yang, Yanyan Pan, Hongye Feng, Qiang Yan, Yanjun Lu, Wanxin Wang, Yu Qi, Hongjian Zhu

“…The fractal dimension has a positive association with the pore structure parameters (SSA, PV), TOC, and <i>R</i>_o and a negative association with the mineral component (quartz, feldspar, clay mineral) contents. Minerals like quartz, feldspar, and clay will slow down the expansion of pores, but when SSA and PV increase, the pore heterogeneity will be greater and the pore structure more complex.…”

Aggregation modes of anionic oxacarbocyanines with polycations in solution and in ESAMs by Andrea Lodi, Glauco Ponterini

“…On the contrary, the latter are extensively and almost exclusively obtained in electrostatically self-assembled multilayers (ESAMs) prepared by alternate polycation/dye adsorption on quartz substrates. The J-aggregate growth on supported polycations is qualitatively shared by the four cyanines, a fact that reveals the crucial role of the double anionic substitutions on the dyes. …”

The impact of coarse aggregate mineral compositions on skid resistance performance of asphalt pavement: A comprehensive study. by Chen Zhang, Lihao Zeng, Huimin Wang, Xin Qu

“…At the molecular level, feldspar showed the highest micro-scale friction coefficient with rubber, while quartz exhibited the lowest. The micro-scale adhesive friction coefficients correlated well with the macroscopic findings (correlation coefficient of 0.81), providing theoretical support for optimizing coarse aggregate selection to enhance skid resistance in road applications.…”
