The Late Great Unconformity of the Central Canadian Shield
The Great Unconformity is a widely distributed surface separating Precambrian rocks from overlying Phanerozoic sedimentary sequences. The causes and implications of this feature, and whether it represents a singular global event, are much debated.

On some aspects of the study of age ratios of rock complexes of the Ukrainian Shield
The article discusses the applicability of stratigraphic dismemberment in the study of high-temperature metamorphic complexes of the Ukrainian Shield. The effectiveness of the stratigraphic method with respect to these complexes was called into question

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Stratigraphic schemes of the Precambrian of the Ukrainian Shield (analytical review)
The first stratigraphic schemes of the Precambrian of the Ukrainian Shield were compiled in 1926 by V. I. Luchytskyi and D. M. Sobolev, and were subsequently developed by numerous authors until 1967.

ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Well XA‐1, completed at a true vertical depth of 11 156 m in the Shawan Sag of the Junggar Basin, is the deepest predominantly near‐vertical well drilled in a sedimentary basin. The figure shows the basin's tectonic framework and well location (a), a structural cross‐section spanning the Shawan Sag and adjacent uplifts (b), and the stratigraphic column

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin
The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...
