Geology
The study of general geology helps us understand the Earth's past and present, and can provide insights into future changes in the planet's landscape and environment.
Physical Properties of Minerals
(How Geologists Identify and Classify Minerals in the Field)Understanding the physical properties of minerals is one of the most fundamental skills in geology. Every...
Unconformities
An unconformity is contact between two rock units.Unconformities are typically buried erosional surfaces that can represent a break in the geologic record of hundreds of millions of years or more. It it called an unconformity because the ages of the layers of rock that are abutting each other are discontinuous at the unconformity. An expected age of layer or layers of rock is/are missing due to the erosion; and, some period in geologic time is not represented.
Plate Tectonics
Plate tectonics is a scientific theory that explains the movements and behaviors of the Earth's lithosphere, which is composed of the crust and uppermost...
Structure of Earth
The Earth's structure is a fascinating and complex arrangement of layers that make up our planet's interior. Understanding this structure is crucial for geologists...
Optical Properties of Minerals
Study of how light passes through thin sections – rock cut and polished to about 0.3 mm thickness
Use properties of light absorption and propogation through a mineral à affected by atomic arrangement and composition
Learn the properties of light associated with techniques governing the use of a petrographic microscope
