As a response to the need to implement a comprehensive tool for the classification of rocks, an interdisciplinary and interuniversity teaching team formed by teachers and students has been constituted. The team develops teaching actions to improve the university learning on petrology and mineralogy. Such actions will have positive repercussions to undergraduates and postgraduates students as well as to secondary and baccalaureate teachers, and to other professional not directly related to teaching. Moreover, with the implementation of such tool will clearly promote the self-learning of students by means of a uniform and common system of classification of rocks aimed to all types of public.
