Una dolomía muy especial. Una propuesta conjunta de trabajo de campo y laboratorio con alumnos de educación secundaria obligatoria.

This paper describes a laboratory activity that reproduces the biological production of hydrogen sulphide to microscale and the basic study of microbial metabolism. This activity helps to high school students to understand why some types of sedimentary rocks produce a fetid smell when they are hit, such as some dolostones, and the impact on their formation.
