Petrology has been written in an easy to read style with a good number of examples, figures and problems for better understanding by the beginners as well as to serve a reference for the researchers.
The igneous section includes texture, mega- and microstructures and petrography of igneous rocks, in addition to norm, modal analysis and graphic plot of petrochemistry data. The chapter on norm includes seventy-five problems with answers. The metamorphic section deals with fabric and petrography of metamorphic rocks and triangular (ACF, AKF and AFM) diagrams. The sedimentary section encompasses texture, structure, ichnofossils, classification and petrography of sedimentary rocks. Chapter on grain size includes detailed laboratory procedure with worked out problems. Chapter on paleocurrent and palaeohydrological analysis elaborates methods of tilt correction, drawing of rose diagram, computation of different statistical parameters and worked out problems. Heavy mineral analysis chapter depicts the separation and identification techniques. Optical properties of thirty-six heavy minerals are given in alphabetical order for easy reference.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
