Abstract

Considering that the volume of natural sand used in the Great Sao Paulo Region (12 million inhabitants) is presently estimated at about 700,000 cubic metres per month (gross volume of US $ 3,5 million) and that there is no organized information about this mineral resource available, the authors think it is high time to develop a research programme on this subject.

After a bibliographic survey on the regional geology, extensive fieldwork was carried out and the samples collected were tested in the laboratory to obtain the mineralogical, granulometric, chemical and technological characteristics.

Also studied was the regional mining types, the calculated reserves and the actual production of the ninety existing mines.

Résumé

La quantité de sables naturels consommée mensuellement dans la Région Métropolitaine de Sao Paulo (12 millions d'habitants) est d'environ 700.000 mètres cubes (valeur proche de 3,5 millions de dollars américains). Le manque d'informations systématiques sur ces produits nécessite un inventaire des ressources.

Les auteurs, à la suite d'une recherche bibliographique sur la géologie de la région, ont réalisé une campagne extensive de prélèvements d'échantillons de sables naturels qui furent soumis aux analyses de laboratoire, dont le but était d'obtenir des informations sur les granularités, les compositions chimiques et minéralogiques ainsi que d'autres caractéristiques géotechniques. Cet article présente, en plus, des données sur les techniques d'exploitation, les réserves et la production actuelle de 90 gisements de sable de la Région Métropolitaine de Sao Paulo.
