What You Can Do

Upload your geochemical datasets—including elemental concentrations, isotope ratios, trace element profiles, or alteration mineralogy—and receive instant ore-type classifications tied to known deposit models. You get detailed interpretations of geochemical signatures, assessment of metallogenic potential, and actionable insights for exploration and resource estimation.

Features

Ore-Type Classification

Automatically classify samples against major deposit models (porphyry, VMS, skarn, epithermal, IOCG, lithium-rich brines) with confidence scores and reasoning.

Element Ratio Analysis

Interpret binary and ternary element ratios (e.g., Zn/Pb, Cu/Mo, rare earth element patterns) to identify geochemical signatures specific to deposit types.

Trace Element Modeling

Evaluate the behavior and significance of trace elements (Ba, Pb, Zn, Ag, REE) in the context of hydrothermal alteration and ore-forming processes.

Alteration Mineral Assessment

Analyze XRD or lithogeochemical proxies for alteration mineralogy (sericite, clay, chlorite, feldspar) and link them to deposit stage and ore potential.

Rare Earth Element (REE) Interpretation

Evaluate REE patterns (Ce anomalies, HREE enrichment, fractionation) to infer magmatic, hydrothermal, or supergene processes.

Data Quality Evaluation

Assess sampling strategy, analytical precision, detection limits; flag outliers, contamination risks, or anomalous data patterns.

Exploratory Report Generation

Compile interpretive summaries with analysis of classification results, geochemical patterns, and exploration recommendations.

Example Output

Classification Result:

  • Sample AU-23-045: Porphyry Copper (confidence 92%)
    • Cu: 487 ppm, Mo: 12 ppm, Re: 0.8 ppm
    • Cu/Mo ratio: 40.6 (typical range: 25–60)
    • Interpretation: Magmatic-hydrothermal Cu enrichment consistent with hypogene porphyry; consider deep drilling.

REE Pattern Analysis:

  • LREE-enriched with negative Ce anomaly (Ce/Ce*: 0.68)
  • Suggests feldspar fractionation + magmatic contribution
  • Inference: Calc-alkaline igneous source, possible porphyry environment

Data Quality Flag:

  • Zn detection limit: 5 ppm (adequate for VMS screening)
  • Pb: 2 samples exceed 1000 ppm—verify lab split duplicates
