Weathering domains and bulk-density assignment in Tanga graphite: deidentified paired differences and reproducibility code

Deidentified supporting data and reproducibility code for an applied geological study of bulk-density assignment in weathered graphite from Tanga, Tanzania. The package contains coded-hole paired differences, pair means, domain/weathering categories, aggregate same-support method summaries and geological volume-transfer summaries, plus standalone reproduction scripts. Original hole identifiers, sample identifiers, coordinates and depths are excluded. Analytical comparisons and scenarios do not establish true density, independent geological truth, total resource uncertainty or a revised mineral resource. Public outputs permit reproduction of the agreement statistics and aggregate model arithmetic; raw project records and depth-dependent modelling inputs are not distributed.
