Study Notes

Types of Structures

Secondary structures are formed after their host rock is lithified.
Boundary structures form the boundary between distinct units.

Forces and Stresses

A force is a vector quantity with magnitude (strength) and direction.
Stress is the intensity of force per unit area.
Internal forces arise from external forces applied.

Examples of Forces

A single axial force applied to the topmost cross-section of a rod.
Seismically active fault in the Gulf of Corinth.

Strain Analysis

Conglomerate in a constrictional state of strain.
