Fluoride in Till Project, Newfoundland, 2017-2018
Project Description
In 2017, till samples collected across Newfoundland from 1985 to 2017 were analysed for fluoride ion (F-) by alkaline fusion with ion-selective electrode determination. It was the first F analysis of older samples and reanalysis of samples collected more recently. Some of the original samples did not have enough archived material for analysis.
Due to the current interest in fluorite and the critical metals associated with fluoride enrichment (e.g., W, Mo, rare-earth elements), fluoride analyses are now a component of the analytical suite for all till-geochemical samples in the province.
Samples from the following areas were analysed for F:
