Description

This book is a collection of papers presented in the 30th International Geological Congress, held in Beijing, on mineralogy. The papers deal with topics on fine structures and crystallographic orientations in biogenic magnetite and thermodynamic properties of minerals.;1. Defects in natural diamonds depending on geological environment 2. Polysomatic relationships in some titanosilicates occurring in the hyperagpaitic alkaline rocks of the Kola Peninsula, Russia 3. Fine structures and crystallographic orientations in biogenic magnetite observed by TEM 4. TEM study of microstructure of omphacite in high-pressure and ultrahigh-pressure eclogites 5. Ordered-disordered stacking structure along the c-axis in calcium rare-earth fluorocarbonate minerals 6. Thermodynamic properties of minerals: The application of Kieffer's model 7.
