geotourism presents a great variety of possibilities. We can mention
examples the floors of São Paulo's shoppings, covered by rocks
with stromatoliths and details in squared stones of countless ancient
consctructions of the colonial Brazil, as Ouro Preto public fountains
or even granite covering buildings in big cities. Our purpose is to
join geological information to the places of easy visibility, offering
the observer another possibility of knowledge that surrounds him.
This kind of geotourism presents important and democratic points because most of people live in metropolis and all cities are able to develope it. Beauty of geology knowledge can supply, in many cases, absence of scenic attractives.
