...Richard N. Abbott; Charles W. Burnham Abstract Energy calculations were used to evaluate the stability relationships for low Ca, low Al biopyribole polysomes in the compositional range defined by (010) pyroxene slabs (P slabs) with composition near (Mg,Fe) 4 Si 4 O 12 and (010) mica slabs (M slabs...

... are petrographically distinctive. The minerals are biopyriboles and are chemically intermediate between anthophyllite and talc. The ideal chemical composition for jimthompsonite and clinojimthompsonite is (Mg, Fe) 10 Si 12 O 32 (OH) 4 , and that of chesterite is (Mg, Fe) 17 Si 20 O 54 (OH) 6 . The new minerals might...

... Amphiboles, in particular, may be factored by (010) cuts into layers that are alternately pyroxene and trioctahedral mica (or talc). The pyroxenes, amphiboles, and trioctahedral micas thus form several such series and we shall designate these minerals, collectively, as the biopyriboles , following Johannsen...

...Massimo Nespolo; Akihiro Umayahara; Jean-Guillaume Eon The modular analysis of the biopyriboles–palysepioles polysomatic series is extended to take into account the local symmetry of each module and the partial operations mapping pairs of modules, to build the corresponding space groupoids. We show...

...Massimo Nespolo; Kenza Bouznari Abstract: Biopyriboles and palysepioles are two polysomatic series traditionally described as built by the juxtaposition of modules taken, respectively, from phyllosilicates and pyroxenes and from palygorskite and sepiolite. We show that all the minerals in these two...

...Bernard H. Grobety Abstract Retrograde hydration of anthophyllite found in ultramafic lenses of the Lepontine Alps, southern Switzerland, resulted in the formation of talc and additional ordered and disordered biopyribole polysomes. Among the ordered sequences, 13 new short-range biopyribole...

... Abstract The concept of polysomatism developed in the ’70s with the fundamental work by Thompson (1970, 1978) on biopyriboles. Since then, this concept proved to be of invaluable help in the description – sometimes in the prediction – of relevant crystal chemical features in several...
