1. Chapter 1 Introduction

2. Content Definition of crystal and mineral Definition of crystal and mineral What is mineralogy? What is mineralogy? Major directions of investigation Major directions of investigation Some preliminary advice Some preliminary advice

3. Definitions Crystal Crystal Homogeneous Homogeneous chemical compound chemical compound with regular and periodic atomic arrangement with regular and periodic atomic arrangement  Not restricted to minerals - most solid matter: sugar, cellulose, metals, bones, DNA Mineral Naturally occurring chemical compound  Most, but not all, minerals are crystalline (some exceptions are opal, mercury, amorphous mineral products from radioactive decay)

4. What is mineralogy?

5. The study of minerals The study of minerals Previously - simple definition Previously - simple definition Today - boundaries opened and overlap other sciences Today - boundaries opened and overlap other sciences Glaciology – ice (a mineral!) Glaciology – ice (a mineral!) Medicine (biomineralogy) - Apatite, carbonates, oxalates, urates Medicine (biomineralogy) - Apatite, carbonates, oxalates, urates Cement industry – non-natural cement minerals Cement industry – non-natural cement minerals Environmental sciences – minerals formed by waste alterations or contaminated water interactions Environmental sciences – minerals formed by waste alterations or contaminated water interactions This course: This course: Rock and ore-forming minerals – small subset of 4000 known minerals Rock and ore-forming minerals – small subset of 4000 known minerals

6. Major directions of investigation Main purpose Main purpose Characterize of properties and chemical compositions Characterize of properties and chemical compositions Conditions of mineral formation Conditions of mineral formation Economically important - define resources & exploration techniques Economically important - define resources & exploration techniques Solution - problems with man-made products Solution - problems with man-made products  Relates to crystallography, chemistry, material science, physics – use basic principles

7. Basic mineralogy

8. Crystal chemistry Crystal chemistry Physical properties Physical properties Mineral formation Mineral formation Crystal growth Crystal growth Processes on earth surface and in interior Processes on earth surface and in interior Chemical reactions, influence of T and P Chemical reactions, influence of T and P Relationships between structure, composition, properties, habit, conditions of formation Relationships between structure, composition, properties, habit, conditions of formation
