Validating geochemical assay data requires standards and duplicate samples that must be extracted and analyzed to ensure that batch results fall within statistical limits.

The montaj Geochemistry extension helps you perform essential tasks for due-diligence and reporting. The extension includes QA/QC tools to confirm the validity and quality of geochemical data, including assay, standards and location data acquired in surveys.

The extension also provides a full range of symbol and grid display and map making functions, which include CAD tools for editing and the creation of interpretations.

The full suite of easy to use geochemical analysis functions includes summary statistics, histograms, scattergrams, tri-plots, principle component analysis, probability analysis and correlation plots.

Kimberlite Indicator Mineral Geochemistry Analysis

Included within the Geochemistry extension is SEMplot, a simple-to-use workflow for analyzing indicator mineral grain geochemistry within the Oasis montaj software environment. The SEMPlot workflow enables the import of the data, mineral identification of the grain based on its chemistry, display of the selected grains on the discriminating graphs and interactive re-classification.

Standard published graphs are included. Users are also able to create their own graphs and overlays. Users may use the raw data, cation, recast, Fe normalized or Fe corrected data stages. The built in OM Dynamic linking ensures the spatial context between the grain graphs, database and maps is maintained. Watch the SEMplot video.

Use montaj Geochemistry to:

• Simplify the quality control process with easy-to-use standard and duplicate handling capabilities
• Analyse multi-element geochemistry with interactive histograms, scatter plots, probability and ternary plots to identify outliers and populations
• Select and subset data interactively from maps based on rock codes, regions or map groups
• In diamond exploration, effectively discriminate samples of interest based on their indicator mineral grain geochemistry
• Identify geochemical trends and anomalies quickly and efficiently
  Enhance your maps with advanced symbol plotting and data gridding techniques
• Combine surface geophysics, geology and geochemistry data into dynamically linked maps

New in the 7.2 release

Duplicate Sample Identification	Duplicate sample identification has been simplified. The Duplicate indicator column now contains the original sample number of the parent sample. This enables you to have multiple duplicates that reference a single parent sample.
Log Options for Box Plots	Box plot graphs have been improved with the addition of a new option for plotting a logarithmic scale.
