Day 1 – Preparation Techniques for Optical Microscopy Analysis

  • Theoretical Session: Standard preparation techniques for optical microscopy analysis (reflected Light microscopy).
  • Practical Session Sampling; mounting; polished blocks improvement and care.

Day 2 – Optical Properties of Opaque Minerals in Polished Sections

  • Theory Session: Using the optical polarized reflected light microscope to identify opaque minerals; Mineral textures and their importance.
  • Practical Session: Common ore minerals identification using the optical microscope; Mineral intergrowths and texture analysis.

Day 3 – Applied Mineralogy to Earth, Planetay and Environmental Studies

  • Theory Session: Complementary electron beam analyses techniques and automated mineralogy to characterize ore minerals and process products and its application to environmental studies.
  • Practical Session: Case-studies in applied mineralogy to earth, space and environmental sciences; Final discussion and conclusions.


Minerals, as the inorganic solids that comprise the rocks, ores, sediments and soils of the Earth and any solid space object, are the essential part of our environment and the universe. The mineralogical characterization of these materials is of paramount importance for the society, no matter what the final objectives of its study are (research, economics or environment). The optical microscopy, particularly the polarizing microscope to examine thin and/or polished sections in transmitted or reflected light, is often the simplest means to identify the mineral species present in a sample. The objectives of this short course are: (1) to introduce the participants to a range of techniques used in samples processing; (2) to teach the theoretical and practical aspects of the polarising microscope and to train competences and skills to identify opaque minerals under the polarised optical microscope and; (3) to understand, based on real case-studies, the practical aspects of applied mineralogy to the different scientific fields.
