Sedimentary Petrology

Recommended Prerequisites

Basic geological knowledge.

Teaching Methods

Conventional classes with transmission and discussion of concepts.

Practical laboratory work involving  macroscopic and microscopic analysis of rocks and minerals.

Practical work centered on the recognition of lithologies in outcrop and interpretation of the sedimentary record.     

Learning Outcomes

1) Understand the criteria and methods of analysis and classification of sedimentary products as well as the reasons that led to its selection

2) Collect, organize and analyze descriptive data of sediments and sedimentary rocks, using the concepts, methodologies and field and laboratory techniques, reaching a standardized classification.

3) Conduct fieldwork and laboratory work in a responsible and safe way, adopting attitudes of analytical rigor;

4) Organize sedimentary data using specific formula and terminology.
