Hours of classroom activity:
Objectives Contents Practical laboratory activity on mesoscopic rock samples aimed at recognizing, describing and classifying sedimentary rocks (terrigenous siliciclastic, carbonate, evaporitic, siliceous, residual, hydrocarbons and coals). The recognition is done by naked eye, with the aid of simple tools such as geologist hummer and lens, steel pick, ruler, diluted hydrochloric acid, water. The recognition and classification of the different types of sedimentary rocks is preceded by theoretical lessons on classification criteria and schemes according to the most common international geologic practice.
Extended Syllabus 1) Introduction to the course. Textures and structures of sedimentary rocks; foundations of sedimentary rocks classifications;2)Terrigenous siliciclastic rocks: grain size-based classification, main compositional features; classification of rudites, arenites and pelites;3) Carbonate rocks: main textural and compositional features; Folk and Dunham classifications; recognition and classification of dolostones and travertines;4) Recognition and classification of evaporitic rocks;5) Recognition and classification of siliceous, residuals, hydrocarbon and coal rocks.

Teaching Methods Taught class in laboratory. Independent and group work of the student, aided and verified by the teacher.
Evaluation methods Verification of learning:
During the course, the learning level is verified by testing the ability of each single student in describing and classifying rocks. The final test consists of a short written test (multiple-choice questionnaire) followed by oral exam consisting in mesoscopic recognition, description and classification of sedimentary rock samples (in general, at least two samples).
