1. Potential Slow Release Fertilizers Based on K2MgSiO4 Obtained from Serpentinite
In this work, a potassium magnesium silicate mineral based on phase K2MgSiO4 was prepared from serpentinite rock and studied as a potential K and Mg slow-release fertilizer. The material was prepared by impregnation of serpentinite/KOH and calcination at 700 °C to produce K2MgSiO4 phase, olivine and forsterite. The release patterns of K and Mg in the stirre

2. Interação de forsterita-91 e da cisteína em condições de química prebiótica utilizando diferentes técnicas espectroscópicas, químicas e mineralógicas
This work simulated prebiotic conditions existed on primordial Earth and studiedthe interaction between forsterite-91, cysteine and artificial seawater. These interactions were studied in aqueous medium at two values of pH 2.0 and 8.0. The samples of olivine plus distilled water and artificial seawater were mixed for 24h, centrifuged, the solids and supernat

3. Petrography and mineral chemisty from Indaiá I and Indaiá II intrusions, western Minas Gerais State / Petrografia e química mineral das intrusões Indaiá I e Indaiá II, oeste do Estado de Minas Gerais
An integrated petrographic and mineral chemistry study has been carried out on ultramafic, potassic to ultrapotassic and silica-undersaturated rocks of kimberlitic affinity of the Indaiá I and Indaiá II intrusions, Western Minas Gerais State, Brazil. These rocks outcrop at the Alto Paranaíba Igneous Province (PIAP), within a N30W-trending, elongated area,
