Record quality tables for the Mineral Resources Data System

Online link https://doi.org/10.5066/P9DYLWMP
Description Measures of quality for each of 304,643 records in the Mineral Resources Data System (MRDS) database. This analysis is intended to separate records that describe those resources well and are trustworthy from those that lack fundamental information or cannot be verified easily. Data are provided in tab-delimited text, Microsoft Excel, and SQLite. PHP code used to carry out the analysis is included for reference.
