Learning Outcomes

By the end of this course the student will be able to:                    

  1. Elaborate X-ray Diffraction analysis data and perform qualitative mineralogical analysis using X-ray Diffraction patterns.
  2. Treat mineralogical and petrological raw data and classify them by using relevant built in diagrams (classification diagrams) or by constructing new ones (binary, ternary, spider, etc.).
  3. Use digital images of mineralogical and petrological samples (mainly from thin or thic sections) for evaluating their mineral modes and textural characterization.

By the end of this course the student will, furthermore, have developed the following general comptence):

  • Develop skills needed for the elaboration of X-ray analysis data and their evaluation through the dedicated databases (PDF databases of the ICDD)
  • Ability to manipulate mineralogical and petrological raw data for classification and characterization purposes.
  • Ability to treat images of mineralogical and petrological samples in digital form in order to deduce significant characterization parameters.
General Competences
  • Searching, analysis and synthesis of facts and information, as well as using the necessary technologies
  • Autonomous (Independent) work
  • Group work

Lectures and Laboratory exercises (hands-on)

  • Evaluation of XRD analysis data through the implementation of dedicated software package and its complemented diffraction databases
  • Use of Software package dedicated to the treatment and elaboration of mineralogical and petrological raw data.
  • Use of a public domain Java image processing program for the modal and textural analysis of mineralogical and petrological materials.
Delivery  Lectures and laboratory work face to face.
Use of Information & Communication Technology
 Use of Information and Communication Technologies (ICTs) (e.g. powerpoint) in teaching.
Teaching Methods
Activity Semester workload
 Lectures (2 conduct hours per week x 13 weeks)  2x13=26
 Laboratory work (2 conduct hours per week x 13 weeks)  2x13=26
 Hours for private study of the student and preparation of home-works and preparation for the Laboratory   48
 Total number of hours for the Course  100
 Student Performance Evaluation
  • Written examination (50% of the final mark)
  • Oral examination (50% of the final mark)

Percentages are valid t only when the student secures the minimum mark of 5 in the final written examination

Greek grading scale: 1 to 10. Minimum passing grade: 5.

Grades <3 correspond to ECTS grade F.

Grade 4 corresponds to ECTS grade FX.

For the passing grades the following correspondence normally holds:

5 <-» E, 6 <-> D, 7 <-> C, 8 <-> Β and >9 <-> A
