Journal Article
Published: 01 March 2000
European Journal of Mineralogy (2000) 12 (2): 411–429.
...Stefano MERLINO; Elena BONACCORSI; Thomas ARMBRUSTER Abstract Clinotobermorite, Ca 5 Si 6 O 17 ·5H 2 O, is a rare mineral, structurally related to tobermorite 11 Å. It is characterized by the presence of structural disorder (evidenced by the diffuseness of the reflections with k odd) which, until...

...Stefano Merlino; Elena Bonaccorsi; Thomas Armbruster The real structures of clinotobermorite, tobermorite 9 Aa, and tobermorite 11 Aa were determined through the application of OD approach, which allowed us to explain their peculiar disorder and polytypic features and to derive the main polytypes...

... related to the hydration state, phases having a 14 Å (plombièrite), 11 Å (tobermorite, kenotobermorite, and clinotobermorite), and 9 Å (riversideite) basal spacing have been described. Tobermorite and kenotobermorite belong to the so-called tobermorite group and differ for their thermal behaviour which...

... Å compounds have been described. In this paper a new nomenclature scheme for these mineral species is reported. The tobermorite supergroup is defined. It is formed by the tobermorite group and the unclassified minerals plombièrite, clinotobermorite and riversideite. Plombièrite (‘14 Å tobermorite...

.... The results of the micro-Raman spectroscopy are in agreement with those of the NMR study, indicating the occurrence of double chains. The observed conformation of the double chains can be easily reached through the shrinking of clinotobermorite-like chains. An intermediate clinotobermorite-like phase...
