The first field guide that allows amateur rock enthusiasts to identify basic rocks and rock formations in a systematic wayMany of us are fascinated by rocks—but identifying them can seem daunting. It’s often tricky even for geologists, who rely on experience, intuition, and in-depth familiarity with rock-forming components. Rocks and Rock Formations allows everyone, amateur or professional, to successfully distinguish these amazing masses of minerals, using only careful observation, a magnifying glass, a pocket knife—and a bit of patience.Jürg Meyer provides a structured approach to the identification of all rocks within the three groups: sedimentary, igneous, and metamorphic. Bringing together more than 530 diagrams and photographs to illustrate essential characteristics, Meyer highlights some basics on rocks—their mineral constituents, structures, textures, fossils, weathering patterns, and more—which are important for a determination. The main part of the book is a handy and thorough identification key, which takes into account all possible rock variations, mixtures, and structural differences. The concluding section of the guide delves into rock systematics.Assuming little prior experience or knowledge, Rocks and Rock Formations is an invaluable resource for rock enthusiasts everywhere. Suitable for beginners and amateurs Helpful, systematic identification key Exploration of all types of rocks More than 530 diagrams and photographs

This new book by the Italian philosopher Roberto Esposito addresses the profound crisis of contemporary politics and examines some of the philosophical approaches that have been used to try to understand and go beyond this crisis. Two approaches have been particularly influential – one indebted to the thought of Martin Heidegger, the other indebted to Gilles Deleuze. While opposed in their political thrust and orientation, both approaches remain trapped within the political ontology that has framed our conceptual language for some time. In order to move beyond this political ontology, Esposito turns to a third approach that he characterizes as ‘instituting thought’. Indebted to the work of the French political philosopher Claude Lefort, this third approach recognizes that the road to reconstructing a productive relation between ontology and politics, one that is both realistic and innovative, lies in instituting praxis. Building on this insight, Esposito conceptualizes social being as neither univocal nor plurivocal but as cross-cut by the dual semantics of political conflict. This new book by one of the most original European philosophers writing today will be of great interest to students and scholars in philosophy, social and political theory and the humanities generally.
