MapMark4 Version Update (Version 1.1)
MapMark4 is a software package originally released by Ellefsen (2017) that implements the probability calculations in three-part mineral resource assessments (Singer and Menzie, 2010). The name is derived from the descriptive phrase “mineral assessment program mark4”—the name “mark4” is chosen because the previous, similar program was called “mark3”. Functions within the software package...
Software for Bayesian Mapping of Regionally Grouped, Sparse, Univariate Earth Science Data (Program BMRGSU)
BMRGSU is software developed by the U.S. Geological Survey for Bayesian mapping of regionally-grouped, sparse, univariate, Earth-science data. This software implements an algorithm that smooths the estimated property across regions so that the deleterious effects of sparse data are mitigated. The algorithm can account for measurements that are censored, it can process multiple datasets...
Software for SIR 'Effect of Data Pooling on Predictions From the Three-Part Method for Quantitative Mineral Resource Assessment-An Investigation of a Previous U.S. Geological Survey Assessment'
The Three-Part Method for Quantitative Mineral Resource Assessment has been used by the USGS to predict mineral resources since at least 1975. These predictions use pooled data, and the effects of the pooling on the predictions is investigated and reported in the forthcoming USGS publication. The calculations and figures for this report are performed with software that will be...
Processing Routines in IDL for Spectroscopic Measurements (PRISM)
USGS Processing Routines in IDL for Spectroscopic Meausres (PRISM) software provides a framework to conduct spectroscopy analysis of measurements made by spectrometers. PRISM functions allows users to compare spectra of materials of unknown composition with reference spectra of known materials.
