Summary

Analytical results for 405, <63µ till samples and 30 field duplicates from west-central Newfoundland, (NTS map areas 12A/05 and parts of NTS 12A/04, 06 and 11‒14) are released. These samples have been analyzed by ICP-OES for aluminum, arsenic, barium, beryllium, cadmium, calcium, chromium, cobalt, copper, dysprosium, iron, lanthanum, lead, lithium, magnesium, manganese, molybdenum, nickel, niobium, phosphorus, potassium, scandium, silver, sodium, strontium, sulphur, titanium vanadium, yttrium, zinc, and zirconium; and by INAA for antimony, arsenic, barium, bromine, cerium, cesium, chromium, cobalt, europium, gold, iron, hafnium, lanthanum, lutetium, molybdenum, rubidium, scandium, samarium, selenium, sodium, strontium, tantalum, terbium, thorium, tungsten, uranium, ytterbium and zirconium. Loss-on-ignition (LOI) was determined gravimetrically, while fluoride was analyzed by ion-selective electrode after alkaline fusion. The analyses have been quality checked for acceptable accuracy and precision. Interpretations of the geochemical data along with an interpretation of the surficial geology will be released later as two separate Open File reports.
