Cristallochimie et propriétés physiques des borates magnésiens des skarns de la province banatitique de Roumanie

Autor: Marincea, Stephan

L'étude apporte des nouvelles données sur les borates magnésiens de cinq gites de skarns de Roumanie : Baita Bihor, Pietroasa, Ocna de Fier, Masca-Baisoara et Cacova Ierii. Les aires de skarn sont developpées autour des intrusions calco-alcalines
