The CADIC’s Geological Resources Program will soon turn 40 years of fruitful development. During this period many projects were carried out and others remain to be implemented. In the course of time three generations of researchers have been formed. Mentioning names would be unfair to those that could be involuntarily omitted. There is still a long way to go. The eagerness for knowledge should not stop.

This book is a tribute to all those people who have worked in the different projects of pure and applied science, and educational, and human resources training, granted to this founding program and associated laboratories of the regional center of CONICET in Ushuaia, Tierra del Fuego, Argentina.

The twenty papers which constitute this book have a genuine Latin appeal, having been written by 50 authors based in Argentina and Spain. All this contributions are concerned with Fuegian geological resources. Everyone concerned with this work hopes that it will prove a fitting and lasting memorial to Nacho Subías, whose personal contribution to our knowledge of this geology was outstanding.
