The Geology of the Canary Islands

636 pages, Elsevier, 2016.

 

The Geology of the Canary Islands provides a concise overview of the geology and volcanology of the Canary Islands, along with 27 carefully planned day excursions comprising trips on all of the islands. Each stop includes a description on how to approach a site and where to park with GPS locations provided.

 

The book covers all the spectacular features of the islands, including active ocean island volcanoes whose origins are linked to a hot spot or plume causing anomalously hot mantle material to intrude the African plate, submarine volcanic sequences uplifted inside the islands, sub- aerial shield volcanoes, and the remains of giant lateral collapses.

 

  • Includes a forward by Prof. C. J. Stillman (Trinity College Dublin), a leading expert on the volcanology and geology of the Canary Islands
  • Features 500 full color images, coupled with in-depth introductory text and a chapter on each island, followed by 27 guided excursions that include all of the seven islands of the archipelago
  • Familiarizes the reader with the variety of volcanic landforms and eruptive products in the Canary Islands and provides practical support in recognition, recording, and interpretation
  • Develops understanding of growth, evolution, and destruction of ocean island volcanoes, promoting temporal and spatial thinking within a given geological framework

Teide Volcano: Geology and Eruptions of a Highly Differentiated Oceanic Stratovolcano.

279 pages, Springer, 2013

 

Teide Volcano has many different meanings:

For the Guanche aborigines, who endured several of its eruptions, it was Echeide (Hell).

 

Early navigators had in Teide, a lifesaving widely visible landmark that was towering over the clouds.

 

For the first explorers, Teide was a challenging and dangerous climb, since it was thought that Teide's peak was so high that from its summit the sun was too close and far too hot to survive.

 

Teide was considered the highest mountain in the world at that time and measuring its height precisely was a great undertaking and at the time of global scientific significance.

 

For von Buch, von Humboldt, Lyell and other great 18th and19th century naturalists, Teide helped to shape a new and now increasingly 'volcanic' picture, where the origin of volcanic rocks (from solidified magma) slowly casted aside Neptunism and removed some of the last barriers for the development of modern Geology and Volcanology as the sciences we know today.

 

For the present day population of Tenerife, living on top of the world's third tallest volcanic structure on the planet, Teide has actually become "Padre Teide", a fatherly protector and an emblematic icon of Tenerife, not to say of the Canaries as a whole.

 

The UNESCO acknowledged this iconic and complex volcano, as "of global importance in providing evidence of the geological processes that underpin the evolution of oceanic islands". Today, 'Teide National Park' boasts 4 Million annual visitors including many 'volcano spotters' and is a spectacular natural environment which most keep as an impression to treasure and to never forget.

Dr. R.I. Tilling (USGS, Chief Scientist Volcano Hazards): "Given its scope and breadth, the 'Carracedo and Troll' book is destined to have a long shelf-life, serving as a valuable reference work for decades to come.

... this book sets a benchmark for the production of similar summaries of the other historically and potentially active volcanoes of the Canary Islands."

Dr. K. Németh (Massey University New Zealand): Overall, I think the first book of the Active Volcanoes of the World series, Teide Volcano, is an excellent work that is detailed enough to be a reference book on the shelf of any volcanologist. The easy to understand style of the book means that it could equally be a general guidebook for a geotourist wishing to plan a trip to Teide. I can recommend this book to anyone with a reasonably good earth science background and a general interest in volcanic geology.

A geological excursion guide to Rum.

The Palaeocene Igneous Rocks of the Isle of Rum, Inner Hebrides.

152 pages, NMSE-Publishing Ltd. The Geological Society of Edinburgh, 2009.

 

This pocket-sized, flexi-back guide gives an overview of the geological evolution of the island of Rum and provides a comprehensive selection of excursions illustrating Rum's Paleocene igneous rocks. It gives advice on travelling to the island, accommodation, weather conditions - and midges.

 

Journal of the Russell Society: 'Overall this is a concise and well-written field guide and a must for anyone planning a geological expedition to the "far flung" islands of the Inner Hebrides - using this guide will make such a trip well worth it.' Proceedings of the Geologists' Association ' ... thorough and clearly presented with numerous photographs, maps and illustrations ... images are sharp and well-captioned. ... a must-aehv guide!' Mineral News ' ... thoroughly researched and wonderfully detailed. ... The descriptions are fabulous ... The guidebook is designed to be practical with a water-resistant cover and colour coding of page edges so that a particular excursion can be found quickly... a top quality publication at a very affordable cost, and I recommend it highly.'
