Senior managers and Heads of Geological Survey Organizations (GSOs) from around the world have contributed a collection of papers to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs continue to provide key scientific information about Earth systems, natural hazards and climate change. As countries adopt sustainable development principles and the public increasingly turns to social media to find information about resource and environmental issues, the generation and communication of Earth science knowledge become increasingly important. This volume provides a snapshot of how GSOs are adapting their activities to this changing world. The different national perspectives presented converge around several common themes related to resources, environment and big data. Climate change and the UN’s Sustainable Development Goals provide an increased incentive for GSOs of the world to work in harmony, to generate knowledge of Earth systems and to provide solutions for sustainable management of the planet.

This is a summary of the known facts about the minerals that make up the rocks, soils, and ore deposits of Colorado. Compilation and abridgment of the literature from 1858, when gold was discovered, through 1957 (with a few additions for 1958 and 1959) is supplemented by information from unpublished sources. Designed to be of use to both professional and amateur mineralogists, the main part of the report describes the chief occurrences of 445 mineral species,42 of them first found in Colorado, together with many subspecies, varieties, and discredited "type" species. Directions for finding these localities are also given in the text. The bibliography contains more than 800 selected references to the most significant literature on the subject
