Silicate structures with sketches, unit formulas of the principle silicate group of minerals. Their
relationship to the sequence of fractional crystallization in a basaltic liquid, their increasing

A few important and common sulfate and phosphate minerals and their mode of occurrence.
Sulfates: SO42Some common sulfates are gypsum, anhydrite and barite. These are evaporate minerals and are
produced by precipitation from saturated surfaces or near-sur
At least 15 sulfide minerals that are important economically. A common mode
of origin for the sulfide minerals.
A common mode of occurrence for the sulfide minerals is the hydrothermal
sulfide deposit in which sulfide paragenesis occurs. (draw and label
Aspects of oxide and hydroxide minerals discussed in class lectures, such as their physical properties
and phase stabilities.
The oxides as a group include compounds in which cations of one of more metals are combined with

Iron-Titanium Group of minerals; solid solutions, their relationship to oxygen
rich and oxygen deficient conditions.
This diagram shows that the iron-titanium group is controlled by the presence or
absence of oxygen in the rock as the rock cooled. The pro
A general classification of the minerals: basis of classification.
The general classification of minerals used in this course is known as the Dana system and is based on
classifying minerals by their chemical composition, and, for silicate minerals, based
