Leicester and Leicestershire topsoils: supporting data, code, QA/QC and sensitivity analyses for technology-associated elements Antonio Peña-Fernández (24688270) Tomás Cámara-Pastor (24688292) Exploration geochemistry Inorganic geochemistry Geochemistry not elsewhere classified Toxicology (incl. clinical toxicology) Metals and alloy materials gallium germanium niobium tantalum tungsten zirconium hafnium tellurium technology-associated elements technology-critical elements urban soil topsoil environmental geochemistry Leicester Leicestershire England QA/QC - quality assurance/quality control <p dir="ltr">This repository contains supporting data, analysis code and audit materials for a study of acid-recoverable gallium (Ga), germanium (Ge), niobium (Nb), tantalum (Ta), tungsten (W), zirconium (Zr), hafnium (Hf) and tellurium (Te) in composite topsoils from Leicester and Leicestershire, UK. It includes original analytical workbooks, analysis-ready N=52 physical-subsample and N=26 site-composite datasets, procedural-blank and QA/QC outputs, the executed R analysis workflow, session information and SHA-256 manifests. It also includes analyses performed during peer review: exclusion of the Beaumont Park Ga anomaly (N=25), leave-one-site-out influence analyses, PCA loading-congruence assessment, Ga/Ge sensitivity, and a raw-to-final Ga concentration-conversion audit based on the original Syngistix workbooks.</p><p dir="ltr">N=26 site composites are the environmental units of inference. N=52 physical-subsample records are used for detection/censoring, QA/QC, within-composite reproducibility and sensitivity only. The repository supports data-processing transparency, auditability and computational reproducibility. It does not constitute independent analytical validation of target-element recovery or matrix-specific trueness.</p> 2026-09-20T18:06:27Z Dataset Dataset 10.6084/m9.figshare.33945742.v2 https://figshare.com/articles/dataset/Leicester_and_Leicestershire_topsoils_supporting_data_code_QA_QC_and_reviewer_sensitivity_analyses_for_technology-associated_elements/33945742 CC BY 4.0
