BGS laboratory: a. XRF analysis for major oxides and trace elements on pressed powder pellets. b. pH: a sub-sample (10 g ±2 g) of the <2 mm fraction (obtained by cone and quartering), slurried with 0.01M CaCl2 solution, with a soil/solution ratio of 1:2.5. Soil pH was measured using a calibrated pH meter. c. Loss on ignition (LOI): 1 g of milled sample was dried in an oven at 105°C for a minimum of 4 hours. The sample was then heated in a furnace at 450°C for 4 hours. LOI was calculated using the weight loss between the sample heated at 450°C and dried at 105°C. 2. SGS Laboratories (Toronto): aqua regia digestion of a 1 g sub-sample, followed by trace element analysis by ICP-OES and ICP-MS. Deep soil/ 'S' sample Samples from the 35–50 cm depth were analysed as follows at SGS Laboratories: 1. Aqua regia digestion of a 1 g sub-sample, followed by trace element analysis by ICP-OES and ICP-MS. 2. Multi acid (HF-HClO4-HCl-HNO3) ‘Near-total’ digestion, followed by trace element analysis by ICP-OES and ICP-MS. 3. Lead fire assay of a 10 g sub-sample of milled material followed by Au, Pd and Pt analysis by ICP-MS. 4. Dilute hydrochloric acid digestion of a 1 g sub-sample followed by sulphate analysis by ICP-OES. Stream sediments 1. BGS laboratory: XRF analysis for major oxides and trace elements on pressed powder pellets. 2. Acme Analytical Laboratories Ltd. (Vancouver): lead fire assay of a 10 g sub-sample of milled material followed by Au, Pd and Pt analysis by ICP- MS; boron analysis by ICP-MS. Waters 1. ALcontrol Laboratories, Hoogvliet,Netherlands: anion and NPOC by Ion Chromatography. 2. GTK, Espoo, Finland: trace element analysis by ICP-AES and ICP-MS. The Tellus survey was funded by the Department of Enterprise, Trade and Investment (DETI), now the Department for the Economy (DfE) in Northern Ireland and the INTERREG IVA programme of the European Union (EU) Regional Development Fund.
