Purpose
Chemical elements and isotopes studied through minerals, fluids, reactions and cycles linking Earth's interior, crust, oceans, atmosphere and life.

Use chemistry to trace Earth processes across reservoirs.
Geochemistry makes element movement measurable by combining thermodynamics, kinetics and isotopic signatures with geological context.
Water-rock reactions
Connect dissolution, precipitation, redox and transport to changing fluid and mineral chemistry.
Isotopes
Use stable and radiogenic isotope ratios as tracers of source, age, process and mixing.
Biogeochemical cycles
Track carbon, sulfur, nitrogen and other elements across rock, ocean, atmosphere and biosphere reservoirs.
Deep Earth & magmas
Infer mantle and crustal processes from melt chemistry, mineral equilibria and elemental signatures.
Keep the boundaries visible.
These separations prevent nearby ideas from collapsing into one another before the subject is understood.
concentration ≠ flux
isotope ratio ≠ element abundance
equilibrium ≠ instantaneous reaction
Questions that organize the Side.
Use these to test whether the model is becoming explanatory rather than merely familiar.
Which geochemical signatures preserve source information and which are reset during later alteration?
How can isotopes distinguish mixing from reaction?
When do kinetic effects dominate predictions based on equilibrium thermodynamics?
What should carry weight here?
Tie chemical analyses to sampling context, standards, mass balance and reaction models; contamination, alteration and open-system behavior must be tested rather than assumed away.
