Abstract
Single micro-crystals of Li2CO3 (zabuyelite) werre observed on (0001) calcite surfaces, epitaxially grown and oriented along the <210> directions of calcite, the (001) forma of zabuyelite being by far the best candidate to form the epitaxial interface. Besides, threefold pseudo twins of zabuyelite were observed in epitaxy on the cleavage (10-14) rombohedron surface of calcite. the new twinning law is described along with the most probable zabuyelite/calcite interface. Further, a general rule is proposed, concerning the conservation of the orientation of the carbonate group across the epitaxial interfaces and twin boundaries in carbonates.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
