#geochemical — Public Fediverse posts

💧 Exploring how contaminated mine waters behave in a carbonate aquifer — through the lens of metasomatic zoning and thermodynamic #geochemical modeling.

Using #PHREEQC simulations, data analysis in #RStats, and geospatial visualization in #QGIS, I’m studying how mine drainage transforms groundwater systems and mineral equilibria over time.

📘 The draft version (v0.75) of my monograph on this topic has already been downloaded 550+ times on #Zenodo — showing how relevant this issue has become for both science and environmental policy.

It’s independent research that links theory, modeling, and practical hydrogeochemical assessment — focused on the long-term impact of mine waters in the Kryvyi Rih region.

Ancient Crystal from #Sahara Reveals a Lost World of Martian Water
#<eteorite, nicknamed “Black Beauty,” is about 4.45B years old, dating to a time when #Mars was new. #Geochemical analysis of zircon grain revealed textural and mineral signatures of thermal water systems that existed on planet when this meteorite formed the earliest epoch in Martian history, known as Pre-Noachian period.
In other words, this grain preserves the oldest direct evidence of hot #water on Mars

"Physical and biogeochemical drivers of solute mobilization and flux through the critical zone after wildfire" just added to our Publications library.

This study analyzed a nine-year series of #nutrient concentrations in three forested catchments in #NewMexico. It focused on chemical changes following a 2013 #wildfire, revealing long-term #geochemical impacts and recovery patterns.

#Steel tools were already in use in #Europe around 2900 years ago. Using #geochemical analyses, the researchers were able to prove that stone stelae on the #Iberian Peninsula that date back to the Final Bronze Age feature complex engravings that could only have been done using tempered steel.

#MacroPhotography is also an interest of Fox (the #photographer). #Minerals and #crystals are especially interesting as subjects, both because of their properties and how their shape and viewing angle reacts with light, but also because of the #geophysical and #geochemical forces that produced them.
In this #photo, you can see a partial #termination (crystal point) of an #amethyst (#quartz/#SiO2/#silicondioxide which often contains inclusions of #iron in the crystal).
#Forcedperspective is also an interesting aspect of macro photography.
