🛠 What does an end-to-end open-source stack look like for an independent hydrogeochemical monograph? Doing full-cycle research—from thermodynamic calculations to print-ready LaTeX typesetting—requires a synchronized toolkit. Here is the exact stack: 🧪 Thermodynamics & Analytics: • #PHREEQC 3.7.3 for aqueous speciation&equilibrium modeling. • #Rstats Stack: RedModRphree, ggtern, sf/terra, tidyverse (ETL). 🗺 GIS & Literature Search: • #QGIS for spatial alignment & cartography. • #Recoll for local full-text search across reference databases. 📚 Typesetting & Reproducibility: • #LaTeX2e + #TeXStudio + #JabRef for typography & #BibTeX references. • xtable for automated R-to-LaTeX data exporting. • #Debian Linux as a main engine. 💡 Takeaway: Zero proprietary software licenses needed. Complete reproducibility from raw analytical data to a print-ready PDF. 🔗 The published version of monoghraph is here: https://zenodo.org/records/20709306 #Hydrogeology #Geochemistry #LaTeX #GIS #OpenScience #DataScience #SvystunovaGully

🌎 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. #Geology #Geochemistry #DataScience #SpatialAnalysis #Springer #GoogleBooks #Lithogenesis
