Electron spectroscopic investigations are used to show that defects at various concentrations are inherently present on surfaces of KNbO3 crystals. Their concentration at the surface is determined by the bulk concentration as well as by diffusion. These defects are important for most classical measurements on KNbO3 and similar materials.

    The Cretaceous Banhadão alkaline complex in southeastern Brazil presents two potassic SiO-undersaturated series. The high-Ca magmatic series consist of initially fractionated olivine (Fo) + diopside (WoEnAe), as evidenced by the presence of xenocrysts and xenoliths. In that sequence, diopside...
