The Primary Scope Of This Text-Book Covers The Transmission As Well As Reflection Optics Of Minerals And The Methods Of Their Studies. To Explain The Optical Behaviour Of Minerals, Some Relevant Concepts In Spectroscopy Have Been Introduced. This Book Fills The Need Of The Students To A Better Understanding Of The Physical Nature Of Minerals Through Studies In Ir-Visible-X-Ray Region.This Book Contains Seven Chapters Titled As: General Optics: Interactions Of Light With Matter, Study In Polarised Light, Optical (Absorption) Sepctroscopic Studies Of Minerals, Reflection Optics, Reflection Spectroscopy, Vibrational Spectroscopy: Infrared And Raman - An Outline, X-Ray Optics. It Also Offers As Appendices The Transmission, Reflection Properties And X-Ray Data Of Minerals.This Is The Only Book That Lucidly Introduces The Principles Of Modern Methods Of Mineral Optics In A Single Volume For The Students Of Graduate And Post-Graduate Levels.

The Universal Stage is an accessory for a polarizing microscope useful in the determination of optical properties of organic and inorganic compounds. Detailed instructions are given for the mounting of crystals, centering the stage, etc. Specialized techniques are given in step-by- step procedures for the orientation of uniaxial and biaxial crystals, the identification of the orientation of uniaxial and biaxial crystals, the identification of the orientation achieved, the mathematical corrections necessary, the determination of the principal refractive indices, optic axial angle, and sign of double refraction. A glossary is included

"This volume contains a sizable suite of contributions dealing with regional impact records (Australia, Sweden), impact craters and impactites, early Archean impacts and geophysical characteristics of impact structures, shock metamorphic investigations, post-impact hydrothermalism, and structural geology and morphometry of impact structures - on Earth and Mars"--
