Petrological and organic geochemical characteristics of oil sands from the Middle Jurassic Yan’an Formation in the southern Ordos Basin, China
Published 2019“…The positive correlations between porosity and permeability and NPI and RQI (R2 = 0.77 and R2 = 0.65, respectively) show that the studied rocks contain many large pores with pore-to-pore throat connection structures that enhance permeability, which is further supported by the relatively high connection coefficient between NPI and RQI (R2 = 0.65). …”

The Seven Sisters Hydrothermal System: First Record of Shallow Hybrid Mineralization Hosted in Mafic Volcaniclasts on the Arctic Mid-Ocean Ridge
Published 2020-05-01“…Barite is ubiquitous, and is sequentially replaced by pyrite, which is the first sulfide to form, followed by Zn-Cu-Pb-Ag bearing sulfides, sulfosalts, and silica. The mineralized rocks at Seven Sisters contain highly anomalous concentrations of ‘epithermal suite’ elements such as Tl, As, Sb and Hg, with secondary alteration assemblages including silica and dickite. …”

Formation of quaternary Zn(AlxGa1−x)2O4 epilayers driven by thermally induced interdiffusion between spinel ZnGa2O4 epilayer and Al2O3 substrate
Published 2023-12-01“…The Al content (x) in ZAGO epilayer gradually increased up to around 0.45 as the annealing temperature was raised to 1100 °C, which was confirmed by transmission electron microscopy (TEM) and energy dispersive x-ray spectroscopy. X-ray rocking curve measurement revealed a small full width at half maximum value of 0.72 °, indicating the crystal quality preservation of the ZAGO epilayer with a high Al content. …”
