The Collected Works of Isaac Rosenberg

Feldspar minerals make up 60% of the crust of the Earth. They are stable in the upper mantle, and are so abundant in the crust that they form the basis of the classification of igneous rocks. At the surface, feldspars weather to form clay minerals which are the most important mineral constituent of soils. The articles in this book review the chemical reactions of feldspars over the whole sweep of pressure and temperature regimes in the outer Earth, and describe the fundamental aspects of crystal structure which underlie their properties. The book covers intracrystalline reactions, such as order-disorder transformations and exsolution, and transfer of stable and radiogenic isotopes, which can be interpreted to provide insights into the thermal history of rocks. It is suitable for final year undergraduates or research workers.

Feldspars and their Reactions

A Vulture Landscape is more than just a book about vultures, in the same way that these majestic flyers are more than just birds. Vultures are a crucial part of many of the world's ecosystems, and without these specialist environmental cleansers the ecosystems wouldn't work properly. A calendar year in the lives of these gargantuan raptors is explored as they live, breed, feed and fly with effortless ease across the skies of the vulture landscape that is Extremadura in central Spain.There are four species of vulture in Europe, and a fifth that is becoming more of a regular visitor as its own global population plummets. The serious conservation issues faced on a day-to-day basis by these species, and their relatives spread across the globe, are explored, issues that in many cases threaten their very survival. However, this book is a celebration of the vulture and the landscape in which it reigns.Using the latest science, his keen eye and his passion for the birds themselves, the author takes the reader on a journey, introducing readers to the vultures, their lives and their landscape. Along the way, much of the other wonderful wildlife of the vulture landscape, from exotic Bee-eaters and bewitching Montagu's Harriers to rutting Red Stags as well as some very excitable cattle, are included. Ian explains how watching vultures is not only addictive, but that it can often lead to vulture gazing, surely the most relaxing form of bird watching there is!
