Volcanism and Volcanic Rocks in Antarctica

Antarctic Record, 1977
The distribution of volcanoes in Antarctica, especially those of the later part of Cenozoic time, has considerable bearing on any interpretations of orogenic patterns or history. The volcanic rocks vary considerably in composition throughout the Marie Byrd Land and Victoria Land, forming a large alkalic province.

Combination of CO 2 ${\text{CO}}_{2}$ storage and geothermal energy production in porous and fractured superhot geothermal systems

Deep Underground Science and Engineering, EarlyView.
The graphical abstract depicts the workflow for porous‐ and fractured‐media simulations, where stochastically generated discrete natural fractures are required for the fracture‐media simulation. Abstract CO 2 ${\text{CO}}_{2}$ leakage is one of the main risks and barriers to geologic carbon storage. However, under the high‐temperature and high‐pressure

Major engineering breakthrough of Well XA‐1, the deepest ten‐thousand‐meter well in a global sedimentary basin

Deep Underground Science and Engineering, EarlyView.
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

137Cs in volcanic rocks.

GEOCHEMICAL JOURNAL, 1977
A non-destructive gamma-ray spectrometry was applied to a number of volcanic products from Japan. Considerable amounts of 137Cs (∼10-13Ci/g) were determined in some volcanic rocks. The presence of 137Cs does not appear to have any relation to the type, age and spatial distribution of the volcanic rocks.

Renewable energy mapping in Northeastern Morocco: A geographic information system‐based comparison of geothermal, solar, and wind potential in the Guercif‐Guilliz and Beni Snassen regions

Deep Underground Science and Engineering, EarlyView.
The graphical abstract summarizes a geographic information system (GIS)‐based synthesis of renewable energy resources in Northeastern Morocco, focusing on the Guercif‐Guilliz and Beni Snassen areas. It visually presents the spatial distribution of solar irradiation and wind energy potential derived from available datasets, alongside their relationship ...
