Structural Control, Evolution, and Accumulation Rates of Massive Sulfides in the TAG Hydrothermal Field

Geochemistry, Geophysics, Geosystems, Volume 21, Issue 9, September 2020., 2020
Abstract The Trans‐Atlantic Geotraverse (TAG) hydrothermal field on the Mid‐Atlantic Ridge is one of the best‐studied hydrothermal systems to date. However, high‐resolution bathymetric data obtained in 2016 by an autonomous underwater vehicle (AUV) reveal new information about the distribution of active and inactive hydrothermal deposits, and their ...

Wide‐Angle Seismic Imaging of Two Modes of Crustal Accretion in Mature Atlantic Ocean Crust

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 6, June 2020., 2020
Abstract We present a high‐resolution 2‐D P‐wave velocity model from a 225‐km‐long active seismic profile, collected over ~60–75 Ma central Atlantic crust. The profile crosses five ridge segments separated by a transform and three nontransform offsets. All ridge discontinuities share similar primary characteristics, independent of the offset.

The Effect of External and Internal Application of Organosilicon Compounds on the Hydrophobicity of Recycled OCC Paper

BioResources, 2016
There are various applications of organosilicon compounds in papermaking. Additionally, organosilicons have been applied to improve the water resistance of some lignocellulosic materials. The performance, however, of such compounds for the hydrophobation

The Effect of Old Corrugated Container (OCC) Pulp Addition on the Properties of Paper Made with Virgin Softwood Kraft Pulps

BioResources, 2013
In this study, old corrugated container (OCC) pulp was added in different ratios (5%, 10%, 15%, 20%, and 25% w/w) to unbleached virgin pulps of both European black pine and Scots pine, and its effects on paper properties were investigated. As a control, OCC pulp-free handsheets were separately produced from European black pine and Scots pine pulps. The

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Massive Sulfide Deposition at the 13°30’N Oceanic Core Complex: Lessons Learned From Coupled Hydro‐Thermo‐Mechanical Modeling

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract Young oceanic lithosphere created at mid‐ocean spreading centers is subject to complex magmatic, tectonic and hydrothermal processes, especially in regions of widespread detachment faulting. This study focuses on the oceanic core complex (OCC) at the Mid Atlantic Ridge at 13°30’N. The OCC hosts the active Semenov‐2 vent field and four inactive
