deep-mantle crystal structuresferropericlasehydrous silicatesSummary The crystal structures of lower mantle minerals are vital components for interpreting geophysical observations of Earth's deep interior and in understanding the history and composition of this complex and remote region. While bridgmanite, ...

These hydrates are the minerals vermicullite, hydrated halloysite and mont-morillonite. Their compositions, subject to iso-morphous replacements, are (OH)MgSiO.8HO; (OH)AlSiO.4HO; and (OH)AlSiO.nHO, respectively. Each structure contains sheets formed by joining tetrahedra of oxygen atoms ...
Nodular is the name of a habit in which mineral crystals grow to form rounded or bulbous structures. The crystals are usually arranged in a radial structure within the nodule, even though the nodules may exhibit concentric banding. In the concentric banding, each layer is composed of crystals ...

Figure 3.3 shows the typical crystal structures: the body-centered cubic (bcc) structure, the face-centered cubic (fcc) structure, and the hexagonal close-packed (hcp) structure. The symmetry of the crystal structure is lower for hcp than bcc and fcc, and the packing density of the atoms ...
Volumes 1 and 2 of Feldspar Minerals were published in 1974, but Volume 3 was not completed because I was forced to devote 3 years to the resolution of unforeseen problems in the construction of an ion probe. By 1977, the incomplete draft for Volume 3 had become obsolete because of the ...
