Closely-spaced carbonate replacement veins: the influence of external stress on focused fluid flow during carbonation of peridotite

Manuel D. Menzel , Janos L. Urai & Estibalitz Ukar
The reaction of serpentinized peridotites with CO2-bearing fluids to listvenite (quartz-carbonate rocks) requires massive fluid flux and maintained permeability despite volume increase. Here we investigate listvenites and serpentinites samples from Hole BT1B of the Oman Drilling Project to improve our understanding of the mechanisms and feedbacks of fracturing and vein formation during peridotite carbonation. The samples are characterized by a high abundance of magnesite veins which are often bundled into closely-spaced, parallel sets. Relative cross-cutting...

Relative Importance of Climate and Humans on Water Storage Changes using GRACE Satellite Data

Bridget R. Scanlon
Understanding climate and human impacts on water storage is critical for sustainable water-resources management. Here we assessed causes of total water storage (TWS) variability from GRACE satellites by comparison with climate forcing, particularly droughts and irrigation water use, in major aquifers in the U.S.. Results show that long-term variability in TWS from 2002 – 2020 tracked by GRACE satellites is dominated by interannual variability in most of the major aquifers. Low TWS trends in the...

From Poverty to Prosperity: The Real Energy Transition

Scott W. Tinker
The energy dialog varies by economic status. Western Europe and the United States suggest there is clean and renewable vs dirty and non-renewable energy, and further that clean energy is cheaper than dirty energy. In this narrative, carbon neutral drives the dialog. Some propose to eliminate coal, oil and even natural gas and nuclear altogether, and suggest that solar, wind and batteries can power the world and address climate change. The IEA just released a...
