The Geological Guide - South Greenland describes the geology of the region along the long fjord Tunulliarfik from Narsarsuaq at the head of the fjord to Narsaq, which is located where the fjord changes name to Skovfjord, and further on to Qaqortoq at the mouth of the fjord. The geology of the region is very interesting. 1200 million years ago, this part of Greenland was the site of volcanic activity. The volcanic cones and most of the lavas have been removed by erosion. Thus, Tunulliarfik and the neighbouring fjords and valleys offer unique opportunities for studies of the geological processes which took place at depth beneath the volcanoes. Furthermore, some of these volcanic "root zones" are outstanding in the world in their richness in rare rocks and minerals. One of the rare minerals is the red tugtupite which has become a popular gemstone and is a sort of ambassador for the region. The area includes the Ilimaussaq complex, which is one of the world's most fascinating igneous complexes because of its extreme enrichment in rare elements expressed in more than two hundred and twenty-five different minerals and in unique multi-coloured rocks. Thirty minerals were first discovered and described in the complex and twelve are unique to it. Narsarsuaq airport is the gateway to a mountainous region dissected by valleys and fjords which give access to a variety of landscapes and provide rich opportunities for a broad spectrum of tourist activities such as hiking, fishing, climbing and visiting towns and settlements and sites of historical or naturalistic interests such as the sites of some of the most important Norse settlements: Brattahlid, Gardar and Hvalsey which can be visited from Narsarsuaq and Qaqortoq. This book presents an introduction to the geology of the region and describes localities of particular geological interest. Many of the described localities are within walking distance from Narsarsuaq, Qassiarsuk, Igaliku and Narsaq, but most localities can only b
