Objectives

Acquisition of knowledge that enable the identification of symmetry operations occurring in crystalline matter; Acquisition of knowledge allowing the stereographic projection of crystallographic models; Acquisition of knowledge and methodologies for the characterization of macroscopic properties and physico-mechanical properties of minerals and identification of expeditiously, minerals.

Learning outcomes and competences

Acquisition of knowledge of fundamental crystallographic laws, identification of symmetry operations occurring in the crystalline matter and the acquisition of knowledge and methodologies to characterize the physical properties of minerals and identification of minerals in an expeditious manner.

Eligibility for exams

Conditions for obtaining frequency: Who has completed the minimum number of practical classes according to the FCUP Regulation.

Calculation formula of final grade

The final grade will be the sum of the marks obtained in the both exames, one theoretical and one practical counted as follows: 60% quoted THEORY EXAM and 40% quoted Practical Exam. Pratical Exam: identification and characterization of the physical properties of minerals (Weight: 40%).
