Deformation Microstructures in Rocks

Study of microstructures is an indispensable component of understanding the structural geology of any terrain. This volume details known structures with attractive colour photographs and also covers related topics such as boundary migration and boudins.

Study of microstructures is an indispensable component of understanding structural geology of any terrain. A number of 'new' microscopic structures such as 'flanking microstructures', trapezoid-shaped mineral grains, reversal of ductile shear sense, micro-duplexes, V-pull aparts, and new minerals nucleating inside host minerals have recently been described in individual manuscripts. However, for the sake of brevity, microstructural papers cannot show all possible variation in their morphology. The proposed book aims to present these structures with attractive colour photographs. Each photomicrograph will have a comprehensive caption. The book also presents grain boundary migration, boudins, symptoms of metamorphic retrogression, and how well known shear sense indicators (S-C fabrics, mineral fish etc.) vary in morphology in serial-sections. The target audience is for graduate and postgraduate geosciences students and researchers of structural geology.

189 colour photos of microstructures Many less known structures in micro-scale Will act as a reference book for researchers and students Includes supplementary material: sn.pub/extras

Résumé

From the reviews: "The book under review presents morphological variations of few selected microstructures in the form of an atlas. ... Throughout the book major findings of fundamental observations of rocks under optical microscope have been well presented. ... This book is an asset for learners, useful for self-study of microstructures and serves as a user-friendly guide for a one-semester course. I recommend the book for libraries of geoscience institutes." (Rajkumar Ghosh, Current Science, Vol. 105 (7), October, 2013)
