Geophysical and geological investigations of Hesten, Vardfjellet and Grunnvåg graphite occurrences, Senja, northern Norway
Abstract
As a part of the MINN project (Minerals in Northern Norway) a helicopter-borne geophysical survey were performed at Senja in 2012 - 2014. Electromagnetic data from this survey showed up anomalies that could be caused by large graphite mineralisations. Geophysical and geological follow-up work was carried out at three locations in 2016, Hesten, Vardfjellet and Grunnvåg, with additional funds from the Troms County administration. A new showing at Grunnvåg was discovered in a short geological visit.
