Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Risk assessment using IEUBK model for the Naica mine tailings

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Mexico has a long history of mineral extraction, during which limited environmental regulations allowed the accumulation of toxic waste near communities, primarily in rural or undeveloped areas. Some of these toxic substances, such as lead, pose significant risks to vulnerable populations, particularly children aged 0 to 7 years.

Geochemical Modelling of the Fracturing Fluid Transport in Shale Reservoirs

Energies, 2022
Field operations report that at least half of the fracturing fluid used in shale reservoirs is trapped. These trapped fluids can trigger various geochemical interactions. However, the impact of these interactions on well performance is still elusive.

Assessing the link between the Geochemistry of Soils and the Bioaccessibility of Arsenic, Chromium and Lead in the Urban Environment [PDF]

, 2012
One of the principal pathways for potentially harmful elements (PHE) in soil to enter the human body is through ingestion. The amount of PHE which enters the systemic circulation is governed by the amount of PHE released in the Gastrointestinal Tract ...

Geochemical modeling of mercury in coastal groundwater

Chemosphere, 2022
The systematic analysis of groundwater in the Greek island of Skiathos revealed a seasonal increase of total mercury concentrations after the extensive groundwater abstraction during the busy and heavily touristic summer months. This contamination was accompanied by a corresponding increase of the chloride content of groundwater, attributed to seawater

Cost Analysis Insights for Offshore CCS Hubs: A Case Study of the Santos Basin, Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT The reuse of decommissioned offshore platforms for geological carbon storage offers a cost‐effective and technically feasible strategy to reduce greenhouse gas emissions in emerging economies. This study presents a comprehensive techno‐economic assessment of offshore carbon capture and storage (CCS) hubs in Brazil, with a focus on the Merluza ...

Trace element mobility during CO2 storage: application of reactive transport modelling [PDF]

E3S Web of Conferences, 2019
The geologic storage of CO2 carries both physical and chemical risks to the environment. In order to reduce those risks, it is necessary to provide predictive capabilities for impacts so that strategies can be developed to monitor, identify and mitigate ...

Post-collisional Tertiary–Quaternary mafic alkalic magmatism in the Carpathian–Pannonian region: a review [PDF]

, 2004
Mafic alkalic volcanism was widespread in the Carpathian–Pannonian region (CPR) between 11 and 0.2 Ma. It followed the Miocene continental collision of the Alcapa and Tisia blocks with the European plate, as subduction-related calc-alkaline magmatism was
