🎉 A small milestone for my hydrogeochemistry monograph about #SvystunovaGully

Today, my Zenodo record passed 1,500 downloads across both released versions — something I never expected when I began this project as a personal, curiosity-driven exploration.

It’s an independent study on groundwater–rock interaction, technogenic metasomatism, and carbonate–water equilibria, based largely on PHREEQC thermodynamic modelling and geospatial data.

I’m grateful to everyone who took an interest, skimmed, downloaded, or shared it.
Your attention gives this work a life I didn’t imagine it would ever have.

❗ And one more thing: in the monograph’s preamble I explicitly thank the developers of free and open-source software. Without their tools — R, PHREEQC, QGIS, LaTeX, Linux, JabRef and many others — this research would simply not have been possible.

📘 A small milestone for my independent research project

I’m honestly a bit shocked.
When I published the first version of my hydrogeochemical monograph on May 27 (v0.72), and then the updated version on August 4 (v0.75), I expected almost no reactions at all.

Today, the combined statistics on Zenodo show:
- 1,400 downloads
- almost 3,000 views

For a niche, highly technical, openly accessible monograph created by one person — this is far beyond anything I imagined.

Thank you to everyone who found the work useful enough to download, save, or read it.
Your interest is the only reason this project keeps growing.

🧪 Mine water + fresh water ≠ simple average

When high mineralized mine waters mix with fresh groundwater, mineral reactions don’t behave linearly.

The graphs below show how saturation indices for selected minerals respond to dilution:
🔹 Copper sulfates (Antlerite, Brochantite, Langite) display clear peaks and drops.
🔹 Gypsum remains undersaturated — yet falls sharply at high dilution.

Each “dip” or “window” reflects a short-lived equilibrium where new mineral phases may form or dissolve — revealing the hidden dynamics of technogenic metasomatism in aquifer systems.

💧 Beyond Diffusion: Groundwater as a Rock–Fluid System

Contaminant plumes in groundwater are often seen as passive — just diffusion and advection through porous media.
But what if we treat them as active geochemical fronts instead?

In my recent modeling work, I describe contamination not as a mechanical process, but as a metasomatic transformation — a reaction zone between aggressive mine waters and carbonate aquifers.

Each sector of the aquifer develops its own thermodynamic balance and mineral stability field.
The plume itself becomes a chemical engine — reshaping host rocks, opening new pathways, and shifting the entire water–rock equilibrium.

🌎 Mapping dominant chemical speciation in a polluted carbonate aquifer

In my recent modeling work, I modeled the dominant forms of element speciation in groundwater within a carbonate system.

Beyond pure geochemical curiosity, this approach provides a practical lens:
– it reveals where mineral precipitation is most probable,
– and helps identify zones where remediation can be most effective.

💻 Combining thermodynamic modeling (PHREEQC) with spatial analysis in R and QGIS turns subsurface processes into actionable insights for water-quality management and contamination mitigation.

🔬 Metasomatic Zonation as a Model of Groundwater Contamination

One of the key theoretical bases in my research is the classical metasomatic zonation model (Korzhinskii, 1960s).

I interpret the contamination halo formed by mine waters not as passive dispersion — but as an active metasomatic system, where aggressive fluids drive alteration and re-precipitation reactions within the carbonate aquifer.

Highly mineralized mine waters create a complex interaction front.
Thermodynamic modeling (based on well-monitoring data) allows identification of several geochemical zones partly analogous to Korzhinskii’s metasomatic sequence.

📊 The image shows my preliminary zoning concept.

💧 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.
