In Portuguese schools the absence of petrographical microscopes is almost a general trend. The high cost of this equipment in relation to the biological microscopes leads to a deficient perception of students by geological subjects. This application simulates real microscopical observations of rocks. Obviously doesn't replace the traditional microscope but, when there isn't another possibility, it is a good way to solve this problem.
This on-line application, a preview for a more complete version that will be available for CD-ROM edition, is available only in portuguese version. Only some pages are available in english.
Students and their teachers from secondary level. The different subjects are also suitable for the general public.
