Muscovite Muscovite is a member of the mica group of silicate minerals (sheet silicates) in which the base of all of the SiO 4 tetrahedra lie in one plane and three corners of the base are shared with the neighbouring tetrahedra. This creates a strongly layered sheet-like structure, hence the term sheet silicate (the sheets are weakly bound together by layers of potassium ions).

The earliest names attributable to muscovite include Muscovy Glass, Silver, and Lapis Specularis (stone mirror); these names appearing in texts in the seventeenth century and before.
Abstract. The present chapter focuses on the scientific and technical research on clay-based nanocomposites. It begins with an introduction reminding the definition of clay nanocomposites reinforcement, the history of evolution of their field of research and development, their properties and their application fields.
Les pneumatites ont des cristaux de quartz, de feldspaths et de muscovite. Quand la température passe de 600°C à 400°C, la concentration en éléments volatils et en B et F augmente. Il y a alors formation de filons de pecmatites avec des cristaux de …
The Q is the concentration of reactants before precipitation, S is the solubility of precipitate in the medium from which it is being precipitated. Therefore, to get particle growth instead of further nucleation we must make the relative supersaturation ratio as small as possible.

No validated biological markers (or biomarkers) currently exist for appropriately selecting patients with cancer for antiangiogenic therapy. Nor are there biomarkers identifying escape pathways that should be targeted after tumors develop resistance to a given antiangiogenic agent.
We describe conjugate systems of shear-enhanced compaction bands oriented oblique to the maximum compressive stress and developed in Paleocene quartz-rich calcarenites formed by the interplay between shearing, mechanical compaction, and dissolution.

Its perfect single cleavage and easy division into thin flexible sheets usually sets muscovite apart from other minerals, except for other micas.
Muscovite from the selvage of a quartz-wolframite vein at Enguialès yielded 40 Ar-39 Ar ages of 305 ± 3 and 306 ± 3 Ma, whereas a plateau age of 312 ± 3 Ma was obtained for muscovite …

Microvasculature is defined as vessels (venules or capillaries) with a maximum average diameter of 0.3 millimeters.As the vessels decrease in size, they increase their surface-area-to-volume ratio. This allows surface properties to play a significant role in the function of the vessel.
