Tellus Geochemistry - Stream sediments

The latest stream sediments data from the Tellus project, managed by the Geological Survey Ireland.
A total of 52 major and trace elements in 9,471 stream sediment samples were determined by XRFS on pressed pellets. Analyses of Au, Pd and Pt were carried out on 9,257 samples using Fire Assay followed by inductively coupled plasma / mass spectrometry (ICP-MS). The survey was conducted on foot; samples were collected approx. every 4 sq km from. For more information please visit tellus.ie.
The following elements were analysed and the data merged with Northern Ireland: Antimony, Arsenic, Barium, Cadmium, Calcium, Cerium, Chromium, Cobalt, Copper, Gallium, Gold, Iron, Lanthanum, Lead, Magnesium, Manganese, Molybdenum, Nickel, Niobium, Palladium, Phosphorus, Platinum, Potassium, Rubidium, Selenium, Silver, Strontium, Thorium, Tin, Titanium, Uranium, Vanadium, Yttrium, Zinc, Zirconium The following elements were analysed and only show the Tellus Border area: Aluminium, Bromine, Chlorine, Germanium, Hafnium, Iodine, Neodymium, Samarium, Scandium, Silicon, Sodium, Sulphur, Tantalum, Tellurium, Thallium, Tungsten, Ytterbium. The following elements were analysed for the South Eastern Ireland area: Aluminium,Antimony,Arsenic,Barium,Bismuth,Bromine,Cadmium,Caesium,Calcium,Cerium,Chromium,Cobalt,Copper,Gallium,Germanium,Gold,Hafnium,Iodine,Iron,Lanthanum,Lead,Magnesium,Manganese,Molybdenum,Neodymium,Nickel,Niobium,Palladium,Phosphorus,Platinum,Potassium,Rubidium,Samarium,Scandium,Selenium,Silicon,Silver,Sodium,Strontium,Tantalum,Thallium,Thorium,Tin,Titanium,Tungsten,Uranium,Vanadium,Ytterbium,Yttrium,Zinc,Zirconium The current coverage includes: Tellus Border survey block (2011-2013, Co Donegal, Sligo, Leitrim, Cavan, Monaghan, Louth) South Eastern Ireland survey block (Historical archive data, collected 1986-1990, re-analysed by XRFS analysis in 2016) Some elements have been merged with topsoil data from Northern Ireland conducted in the mid ninties and noughties.
