Who Should Attend
This course is designed for petroleum geologists who are working in siliciclastic environments. The course is also useful for geochemists, and scientists interested in learning the fundamentals of siliciclastic petrography.

Upon successful completion of the course, students will be able to identify textures, classify siliciclastics, describe their textures, discuss mineralogy, explain diagenetic processes, and analyze factors affecting porosity and permeability.
