Prerequisites

There are no formal prerequisites. However, a previous knowledge of the following topics is convenient:

1.- Chemical formulation

2.- Chemical valence and bonding types

3.- Matrix calculus

4.- Vector calculus

Objectives and Contextualisation

This is a basic course in first year, with direct application in second year Mineralogy as well as in Petrology and other courses in the following years.

As a consequence, the objectives are:

I. Acquisition of basic knowledge about:

1 - The crystal lattice and its mathematical description, as a basis for the description of the crystal structures of minerals.

2 - The crystal symmetry and its mathematical description, as a basis for the description of the crystal structures of minerals.

II. To know the basics of X-ray diffraction in crytals, for applying this knowledge in second year Mineralogy.

III. To visualize in 3D crystal structures in their symmetry.

IV. To perform simple tasks with crystallography software.

V. To have the basis for relating the physical properties of solids with their crystal structure.

Competences

Learn and apply the knowledge acquired, and use it to solve problems.
Relate the physical properties of matter to its structure.
Work independently.

Learning Outcomes

VI. X-ray diffraction in crystals

Practical sessions

(the order of the practical sessions can change)

II: Lattice planes

III: Close packings

IV: Metric tensor and its applications

V: 3D representation of crystal structures with crystallographic software.

VI: Point symmetry. Crystal models I

VII: Point symmetry: 3D interactive PDF files

VIII: Point symmetry. Crystal models II

IX: Space symmetry. Symmetry elements

X: Space symmetry. Analysis of crystal structures

XI: X-ray diffraction

Methodology

Practical sessions will take place in in a space with large tables where the students can work in group. Some of the sessions will take place in computing classrooms using crystallographic software. The students will have a guide with the work to make. The teacher will provide assistance and will deliver the correct results, either during the session or in the virtual campus.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Activities

Title	Hours	ECTS	Learning Outcomes
Type: Directed
Practical sessions	25	1	1, 2, 3
Theory classes	26	1.04	1, 2

Assessment

The avaluation includes two mid-term exams, one by the middle of the course and the other in the end. The avaluation will include also the delivery of several assignments.

The second-chance exam is the opportunity of repeating one or two of the mid-term exams. In this case, the qualification obtained in the second-chance exam will replace the corresponding mid-term exam. The second-chance exam do not affect the qualifications of the assignments delivered.
