ABOUT COURSE

COURSE OBJECTIVE

This Advanced Structural Geology course is useful for exploration geologists and geophysicists. The conservation of rock volume can be an important constraint in evaluating the feasibility of a geological interpretation. Volume-balanced cross sections are especially useful in structurally complex areas. Learn to evaluate common mistakes in structural interpretations. Construct balanced cross sections in a “hands on” workshop emphasizing the kink-bend model, fault-bend folding, and fault-propagation folding. Some exercises will involve the use of computer software for forward modeling.

• Students will learn to evaluate the feasability of geologic models.
• Learn how to construct models of fault-bend folds and fault-propagation folds with the kink method.
• Learn to construct “volume-balanced” cross sections.
• Students learn to apply kink method to seismic interpretation.
• Exercises may involve the use of Move or GeoSec geologic modeling software.
