dc.descriptionCultures of Aspergillus fumàrícus and Penicillium rotundum isolated from soils, grown in Czapeck-Dox liquid, have shown the capacity to attack both diopside and hornblende, the principal components of diopsidite, colletect between Amaralina and Rio Vermelho beaches close to the Méridien Hotel (Salvador, BA). These rocks occur as enclaves in high grade metamorphic rocks, metamorphosed in granulite facies. The diopsidite is holomelanocratic, has a black color, is medium grained with a massive structure and has a granoblastic texture. The microorganisms cause ferric-iron, calcium and magnesium solubilization after three successive incubatíons, each of 90 days. Microscopically, it has been observed that Aspergillus fumaricus atacks more strongly than Penícillium rotundum, which, in turn, attacks more strongly than water, which, in turn, attacks more strongly than the culture médium. The minerals altered to amorphous materials not identified by a "standard" microscope. These products are líght to dark grey or black in colour, isotropic. Is was observed that diopside alters more than horndlende and the last, more than plagioclase.en-US
