Exploration is looking for minerals by means of surveys, drilling and taking samples. This includes extracting minerals for purposes other than producing them commercially. <...>

The enhancement of dissolution of quartz under the influence of clays has been recognized in sandstones for many years. It is well known that a grain of quartz in contact with a clay flake dissolves faster than when in contact with another grain of quartz. This phenomenon promotes silica transfer during the diagenesis of sandstones and is responsible of deformation and porosity variations. Here we make an attempt to explain the process of this rock deformation using a pressure solution mechanism.

Geophysics is the application of the principles of physics to the study of the earth. The subject includes, strictly speaking, meteorology, atmospheric electricity, or ionosphere physics, but it is in the more restricted sense, namely the physics of the body of the earth, that the word geophysics will be used in this monograph.

Principles Of Engineering Geology by K.M. Bangar is a book that is designed as a basic text for the students of B.Sc in Geology, B.E. in Civil Engineering and Mining Engineering, A.M.I.E. Section B, and also Diploma In Mining Engineering. This book can also be referred to by those who are appearing for the different competitive examinations conducted by the U.P.S.C. and other State PSCs. The book also provides the required information for the keen readers of Geology. Principles Of Engineering Geology covers topics such as physical geology, minerals, study of various crystals, and also the different types of rocks, such as igneous, sedimentary, and metamorphic rocks. The book also covers different geological structures and the Indian geology. Some of the other topics that are covered in the book are different deposits of ore and the role of engineering in geology. Various methods of exploration and surveying techniques are also covered in the book.K.M. Bangar is also the author of Engineering and General Geology.
