Company samples in Greenland

The dataset contains geochemical sample data from four company reports submitted to the Ministry of Mineral Resources (MMR) and previously to the Geological Survey of Denmark and Greenland (GEUS). The reports were originally delivered in paper format and later scanned. The geochemical data have been digitally restored through optical character recognition of scanned documents and georeferencing of sample locations. The dataset has been uploaded to the GEUS sample database with necessary adjustments to sample names and metadata. The dataset includes samples with coordinates but without geochemical analyses, as well as samples with analyses lacking unambiguous coordinates.

Purpose
The purpose of the dataset is to make historical company-reported geochemical data digitally accessible and searchable through the GEUS sample database. The dataset supports geological and geochemical analyses but must be used with consideration of the documented methodological and analytical limitations.

Statement
The dataset is based on four historical company reports: Allen & Harris, 1980; Coppard et al., 1992; Harris et al., 1992; and Pearson & Joudrie, 1995. The reports were originally submitted in paper format and later scanned as PDFs. The geochemical data have been digitally restored through optical character recognition of text and numerical values, as well as georeferencing of sample locations. Errors may have been introduced during scanning, optical character recognition and digitisation. The match between geochemical analyses and geographic coordinates is not unambiguous in all cases, and samples may occur with coordinates but without analyses, as well as analyses without unambiguous coordinates. Information on analytical methods, detection limits, measurement uncertainty, laboratories and grain-size fractions is generally sparse or not reported in the original sources. During import into GEUS’ sample database, sample names and selected metadata were adapted to the database structure, and sample names may therefore differ from those in the original reports. The dataset should be used with these reservations, and the original reports should be consulted for documentation and scientific context.
