Box Models of Volatile Cycles over the Entire Phanerozoic [PDF]

open access: yes, 2006
Three stand-alone geochemical box models have been developed to simulate globally coupled biogeochemical cycles. These models reflect the evolution of the participating biotic and abiotic constituents in marine and terrestrial environments, including the

Structure and lithogenesis of hydrothermal clays from Nizhne-Koshelevo geothermal anomaly (Southern Kamchatka)

open access: yesЛитосфера, 2017
On the basis of well drilling and prospect-hole digging and detailed level-by-level approbation the lithological structure of hydrothermal clays of Nizhne-Koshelevo geothermal anomaly, one of the largest on Kamchatka, is investigated.

Estimation of CO2 release from thermal springs to the atmosphere [PDF]

open access: yes, 2019
Introduction Geodynamically active regions have long been recognized as areas of anomalous Earth degassing [Irwin and Barnes, 1980]. Areas found at plate boundaries are characterized by seismic, volcanic and geothermal activity as well as ore deposition.

In‐Tip Nanoreactors for Simultaneous Proteolysis and Enrichment of Phosphorylated Peptides

open access: yesAnalytical Science Advances, Volume 6, Issue 1, June 2025.
ABSTRACT Protein phosphorylation introduces negative charges on the hydroxyl groups of serine, threonine, and tyrosine residues, reducing the ionization efficiency of phosphorylated peptides. The low abundance of phosphorylated peptides often diminishes their detection using mass spectrometry. To enhance the identification of the low‐abundance peptides,

Beyond Conventional Approaches: The Revolutionary Role of Nanoparticles in Breast Cancer

open access: yesMedComm – Biomaterials and Applications, Volume 4, Issue 2, June 2025.
This review explores integrated approach of nanotechnology to breast cancer diagnosis and treatment. We highlight imaging techniques for tumor detection and biomarker analysis in biological samples for early diagnosis. Advanced therapies, including targeted drug delivery and antibody‐drug conjugates, enable precise medication transport to cancer cells,

What Is the Energy Budget of Subduction Zone Hazards?

open access: yesReviews of Geophysics, Volume 63, Issue 2, June 2025.
Abstract Subduction zones are host to some of the largest and most devastating geohazards on Earth. The magnitude of these hazards is often measured by the amount of energy they release over short periods of time, which itself depends on how much stored energy is available for the geologic processes that drive these hazards.

Ore‐controlling structures revealed by magnetic and resistivity anomalies in the Linares–La Carolina mining district (Spain)

open access: yesGeophysical Prospecting, Volume 73, Issue 5, Page 1379-1395, June 2025.
Abstract The effectiveness of magnetic and electromagnetic geophysical methods in delineating geological structures with mining implications was analysed in this study, specifically for structures that affect the possible extension of the lead‐based metal phylonian deposits concealed by young sedimentary cover.

The Cu–Au–Mo deposit mineralization dynamics at the northern margin of the North China Craton and the southeastern margin of the Central Asian Orogenic Belt based on crustal oxide content

open access: yesGeophysical Prospecting, Volume 73, Issue 5, Page 1651-1666, June 2025.
Abstract The study of the mineralization dynamics of the Cu–Au–Mo deposit at the northern margin of the North China Craton and the southeastern margin of the Central Asian Orogenic Belt is important for understanding metallogenic settings. We calculated the crustal oxide content in heterogeneous systems using crustal temperature, seismic wave velocity (

Neon Isotopes in Geothermal Gases From the Kenya Rift Reveal a Common Deep Mantle Source Beneath East Africa

open access: yesGeophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract The seismic velocity structure beneath East Africa suggests interconnected corridors of hot mantle are upwelling beneath the continent. However, the geochemical evidence for deep mantle in Ethiopia‐Kenya‐Tanzania volcanism is sparse questioning the existence of superplume.
