Geophysical and geomechanical characteristics of Gabbro from locality Pantelej, Macedonia [PDF]
The paper represents the geophysical and geomechanical characteristics of gabbro from the locality Pantelej in Macedonia. This gabbro is wide spread and it intruded in Paleozoic chlorite - sericite and graphite schists.

The Pobei mafic-ultramafic complex in northwestern China comprises magmatic Cu-Ni sulfide ore deposits coexisting with Fe-Ti oxide deposits. The Poshi, Poyi, and Podong ultramafic intrusions host the Cu-Ni ore. The ultramafic intrusions experienced four

U–Pb geochronology and Hf isotope data from the Late Cretaceous Mawat ophiolite, NE Iraq
The Mawat ophiolite, NE Iraq, is one of the Neo-Tethyan ophiolites within the Iraqi Zagros orogen. It consists of many metre-to kilometre-sized tectonic slices of serpentinized dunite, peridotite, gabbro, basaltic rocks and associated oceanic ...

The effects of wind power plants on surrounding vegetation remain poorly understood. Vegetation surveys at three Norwegian wind power plants commissioned 4, 12, and 19 years ago showed that roads caused shifts in plant functional strategies toward species with ruderal strategies.

Abstract Porosity and permeability are crucial factors influencing hydrothermal flow in the oceanic crust. This paper provides a comprehensive overview of measurements and estimates of porosity and permeability. Although scientific drilling projects have yielded direct measurements of these properties, available data remain limited, particularly for ...

The ODP/IODP multileg campaign at ODP Site 1256 (Cocos plate, eastern equatorial Pacific) provides the first continuous in situ sampling of fast spreading ocean crust from the extrusive lavas, through the sheeted dikes and down into the uppermost gabbros.

Abstract Natural hydrogen (H2) is a promising clean energy resource and a significant component of geothermal gases, yet its origins and release mechanisms remain poorly constrained. Here, we present geochemical and isotopic data (CO2, N2, Ar, H2, He, CH4, 3He/4He, δ13C‐CO2, and δ13C‐CH4) for hydrothermal gases from the Changning–Menglian suture (CMS),

Investigating the Magma Reservoir of Taupō Volcano Using Receiver Functions
Abstract The Taupō Volcanic Zone (TVZ), one of the most active volcanic systems globally, poses significant hazards. To improve our understanding of crustal structure and implications for hazards, we apply P‐to‐S receiver function analysis, supplemented by S‐to‐P for validation, to temporary seismic network data surrounding Taupō volcano. This provides

We examined the petrography, petrology, and geochemistry of two types of gabbroic xenoliths (A- and B-type xenoliths) in olivine basalt and biotite rhyolite units among the dominantly rhyolitic rocks in Niijima volcano, northern Izu-Bonin volcanic arc ...
