description: Metal oxide minerals ubiquitously exist with organic matter in sedimentary rocks. Therefore, the chelation of organic matter on mineral surfaces is expected to affect mineralization and the stability of detrital grains, such as quartz. Understanding the complexation of goethite-humate chelation with quartz is important because quartz is the fundamental material in reactions that affect the petrophysical properties and sorption capacity of sandstones. However, this complexation interaction has not been characterized. Hence, this study uses Field emission scanning electron microscopy (FESEM) and Transmission electron microscopy (TEM) as well as Fourier infrared transform and (FTIR) and X-ray photon (XPS) spectroscopic methods to characterize the chelation of humate on goethite, and the complexation of this chelation with quartz. The FESEM showed the adsorption and coating of the synthesized chelations on quartz substrates, forming secondary precipitates that occlude the quartz grains. The TEM images depict the chelations intruding the lattice spaces of quartz. The characteristic peaks for Fe-O, Si-O-Si, C-H and H-O-H bonds as well as that of XPS further confirmed the adsorption interactions between goethite-humate chelations and quartz. The study showed that the complexation reaction controls the binding of iron oxides to quartz thereby influencing the porosity of siliciclastics.
