Weathering Profile
nounPronunciation: /ˈwɛðərɪŋ ˈproʊfaɪl/
A vertical sequence of rock layers showing progressive chemical and physical alteration from fresh rock at depth to oxidized minerals and clay minerals near the surface. In abandoned mines, weathering profiles indicate the extent of oxidation and predict future contaminant generation.
Plain English
The gradual breakdown of rock from fresh material deep down to altered, decomposed material near the surface.
Etymology & History
Usage
"The weathering profile in exposed pit walls reveals sulfide oxidation rates and predicts long-term AMD generation."
Style guide notes: Describe weathering profile characteristics using depth intervals and mineral composition percentages.

Frequently Asked Questions
Why study weathering profiles in abandoned mines?
They reveal oxidation extent, predict AMD generation rates, and guide remediation design decisions.
What does a typical weathering profile show?
Fresh rock transitions upward through partially weathered rock to clay-rich, oxidized material at the surface.
Why Test Candidates on This?
Useful for predicting long-term geochemical stability and contaminant generation potential at reclaimed sites.
