Abstract The magnetic susceptibility of ordered and partially disordered manganogrunerites (composition Ca0.1Mn1.9Mg1.25Fe3.562+Fe0.383+Si7.81O22(OH)2 and Ca0.24Mn1.57Mg2.27Fe2.762+Fe0.323+Si7.84O22(OH)2) has been measured ...
The crystal structure of a manganoan cummingtonite, composition ([M4])(Na0.13Ca0.41Mg0.46Mn1.00) 102,614(2)(n) from Talcville, New York, has been refined at high temperature using in situ neutron powder diffraction. The ...
The partitioning of Fe and Mn between the large M(4) site and the octahedral sites, M(1,2,3) in the amphibole structure has been investigated in two natural manganogrunerites of compositions Ca0.1Mn1.9 Mg1.25Fe2+ 3.56Fe3+ ...
