The Peloso complex is a 1000m thick gabbroic body composed of two main layered zones (ZA and ZB) that are made up of cyclic macrolayers of olivine gabbro, leucogabbronorite and anorthosite cumulates, ...
Possible Role of Microbial Polysaccharides in Nontronite Formation
Biomineralization Extracellular Polysaccharides Microbes Micromorphology Microstructure Nontronite
2011/12/5
Abstract: Nontronite and microbes were detected in the surface layers of deep-sea sediments from Iheya Basin, Okinawa Trough, Japan. Nontronite, an Fe-rich smectite mineral, was embedded in acidic pol...
Perturbative Theory of Mica Polytypism. Role of the M2 Layer in the Formation of Inhomogeneous Polytypes
Crystal Growth Long-Period Polytypes Mica Polytypism
2011/12/2
Abstract: A new model is proposed to explain, within the framework of the theory of spiral growth of Frank, the formation on inhomogeneous mica polytypes. This model relates the interaction and cooper...

Microbial mats on the surfaces of modern, marine stromatolites at Highborne Cay, Ba-hamas, were investigated to assess the role of microbial processes in stromatolite forma-tion. The Highborne Cay str...
Solid-solid reactions mediated by a gas phase: An experimental study of reaction progress and the role of surfaces in the system olivine+iron metal
Solid-solid reactions olivine+iron metal
2012/4/1
The intergranular fluid involved in solid-solid reactions is tacitly assumed to be a melt or a (C-O-H-S-Cl-F)-bearing phase. We have studied the system olivine 1metal using dif-fusion couple experimen...
