Added 25 mg/L Silicon (Si) and 5 mg/L Aluminium (Al) to the hydrogeochemical baseline of the Svystunova Gully mine water impoundment, modeling clay mineral phase equilibria using RedModRphree + PHREEQC (Thermoddem database, T = 12°C).
Key thermodynamic outcome (pe–pH diagrams across pH 2–10):
The solid-phase stability field is completely dominated by Beidellite(Na) and acidic forms of montmorillonite (Hmontmorillonite).#Geochemistry #Hydrogeology #PHREEQC #ThermodynamicModeling #EnvironmentalDataScience #Rstats #Geoscience #ClayMineralogy #SvystunovaGully

Biogeochemical cycle (Biogeochemical cycle 🔄)
A biogeochemical cycle, or more generally a cycle of matter, is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule...

Du nouveau chez Minetosh online (https://www.minetoshsoft.com):
Tous les modules d'« AmphiCalc-1 » destinés au calcul et à la classification des amphiboles ont été révisés. La saisie des valeurs pour déterminer la teneur en Fe₂O₃ et calculer les valences a été améliorée et simplifiée. Les calculs sont désormais effectués directement lors de la saisie. De plus, la valeur recherchée peut maintenant être déterminée plus rapidement à l'aide d'un curseur.
Malheureusement, il y a des problèmes avec les navigateurs basés sur Chromium (par exemple Vivaldi). Firefox et ses dérivés fonctionnent. Désolé ! Je vais essayer de régler ce problème dès que possible.

News from Minetosh online (https://www.minetoshsoft.com):
All components of “AmphiCalc-1” used for the calculation and classification of amphiboles have been revised. The process of entering values to determine the Fe₂O₃ content and calculate valences has been improved and simplified. Calculations are now performed immediately as values are entered. In addition, the desired value can now be determined more quickly using a slider.
Unfortunately, there are issues with Chromium-based browsers (e.g., Vivaldi). Firefox and its derivatives work fine. Sorry! I'll try to fix this as soon as possible.

Deploying a fleet of high-altitude aircraft to artificially dim the sun is not a triumph of human ingenuity; it is a tragic, desperate monument to our collective failure to live within the absolute thermodynamic limits of our world. Yet, if faced with the imminent collapse of the ecosystems that sustain billions of lives, it may quickly become the most desperate, necessary responsibility we ever undertake.

🌎 Why 1960s Geoscience Classics Still Matter in Data Science
Data without domain expertise is noise. It’s easy to get caught up in R or ML, but foundational science drives true insight.
I'm revisiting N.M. Strakhov's masterpiece "Principles of Lithogenesis" (1960-62, translated 1967). Springer’s 2014 digital reprint (Google Books) proves its value. Over 60 years later, his systematic approach to sedimentary environments and geochemistry remains highly relevant.
❓ Why this matters for spatial analytics:
🔹 Ground-Truthing: You can't model watershed contamination, mine waters, or deposits via desktop sowtware alone if you ignore baseline lithological and geochemical laws.
🔹 Feature Engineering: The best domain features come from understanding physical processes—like how basins and geochemical barriers function.❗ Tools change, but physical laws are timeless. Understanding both turns raw data into actionable insights.

🔹 Feature Engineering: The best domain features come from understanding physical processes—like how basins and geochemical barriers function.❗ Tools change, but physical laws are timeless. Understanding both turns raw data into actionable insights.

Earth, Sweet Earth ( Science For Everyone) by Ekaterina Radkevich
The book is based on the author’s impressions of her numerous expeditions in the many countries. It is a fascinating narrative rather than a mere record of facts irrespective of how scientifically valid they can be. The book is bound to be appreciated as a piece of absorbing reading by anyone who cares to increase the scope of his or her competence about our sweet home of a planet that must be saved from destruction at all costs.
Ekaterina Radkevich, Corresponding Member of the USSR Academy of Sciences, is one of the most distinguished geologists whose works are well known in her own country and in many other parts of the world. The overwhelming success of her publications is chiefly due to her indefatigable practical activity in the USSR and elsewhere and her unflagging interest in theoretical research which she has been conducting for quite some time at the Institute of Geological Studies in the Far East (Viadivostok).
Note: This book was the last remaining volume in the Science for Everyone Series! This completes volume the SFE series in English.
Many, many thanks to Hassaan Ali who purchased and posted this book to us to complete this series. Much appreciated help!

Rock Weathering Can Counteract River CO2 Emissions Induced By Permafrost Thaw

H/T @aaron Bufe
“[The researchers] measured carbon emissions and water chemistry in 50 headwater rivers draining 780,000 km² of the Tibetan Plateau.
The rivers flow in landscapes underlain by continuous permafrost and landscapes in which the permafrost has retreated since the last glacial maximum. They collect[ed] organic carbon from soils and dissolved inorganic carbon that is fixed by rock-weathering.
Where the permafrost cover is continuous, rivers emit CO2 from degrading (permafrost) soil carbon. Weathering reactions in these catchments are relatively slow.
In landscapes with (almost) no permafrost, carbon fluxes from weathering are faster than CO2 emissions from rivers.
Thus, as permafrost landscapes transition to landscapes without permafrost cover, chemical weathering reactions may play an ever more important role in riverine carbon cycling.
Interestingly, weathering can affect the carbon cycle in different ways. Where sulfide minerals are present, weathering reactions can emit CO2. Where silicate minerals dominate, weathering draws down CO2 from the atmosphere…”

“Climate-induced permafrost thaw unlocks large stores of organic carbon that are mineralized and emitted as carbon dioxide (CO2) from rivers to the atmosphere. Concurrently, warming and permafrost thaw can increase mineral weathering rates, thus affecting the release and sequestration of inorganic carbon. Yet how these biological and geological carbon cycles interact and jointly affect CO2 dynamics (emission compared with drawdown) in permafrost rivers remains unknown. Here [they] combine[d] CO2 emissions, organic and inorganic solute concentrations, dual carbon isotopes (δ13C–Δ14C) and geochemical modelling to infer how permafrost thaw may affect river biogeochemistry over decades to centuries across the Qinghai–Tibet Plateau. Leveraging a gradient of thermal permafrost degradation, we find that river CO2 emissions decline, whereas solute fluxes from rock weathering increase with decreasing permafrost cover. Across this region, net CO2 drawdown fluxes from rock weathering are about 35% of river CO2 emissions, varying from around 15% in catchments with continuous permafrost to more than 100% in catchments with discontinuous or isolated permafrost. Thus, carbon fluxes from chemical weathering may become increasingly important with ongoing permafrost thaw, potentially even outpacing river CO2 emissions. [Their] findings disentangle the interplay between biological and geological carbon fluxes that are important for the cryosphere and the global carbon cycle…”

A methodological audit of regional hydrogeochemical literature reveals a systemic gap. Legacy environmental assessments for the Kryvyi Rih Iron Ore Basin rely on frameworks designed for fresh water, which fail when applied to highly mineralized mine waters. Standard equilibrium algorithms are inadequate for environments with extreme ionic strength.
This limitation extends to mass transport: conventional modeling overlooks density-driven convection and gravitational settling of heavy brines, leading to inaccurate spatial migration models.
Overcoming this inertia requires a return to the fundamental laws of chemical thermodynamics and multiphase flow physics, aligning predictive models with actual environmental constraints.
