Читать книгу Iceland Within the Northern Atlantic, Volume 1 - Группа авторов - Страница 20

The Greenland–Iceland–Faroe Ridge (GIFR) consists of a shoal interspersed with three fairly deep channels (about 2,000 m), which steers the North Atlantic from Greenland to the Faroe Islands, leaning against Iceland. It forms a relief of crucial importance not only as a recording of the last phases of the opening of the North Atlantic, but also for understanding the formation of the current thermohaline circulation, one of the major drivers of the evolution of our climate.

The GIFR crust has an anomalous thickness, ranging from 25 to 40 km, equivalent to that of a continental crust. It is not associated with any interpretable magnetic anomalies except locally between Iceland and the Faroes (Nuuns et al. 1983; Hjartarson et al. 2017).
