Reference Entry
The definitions of the term "mica" are presented. The term mean a crumb. It also refers to a mineral composed of various silicates of metals that occurs in thin, laminated scales. The reference entry is from the "Taber's Cyclopedic Medical Dictionary," published by F.A. Davis Co. The pronunciation of the term is also provided.

    We report amphibole and mica [sup 40] Ar/[sup 39] Ar ages from the Makkovik Province. Amphibole ages from metamorphic rocks decrease towards the interior of the province, indicating a first-order pattern of monotonic cooling with progressive migration of the province into a more distal back-arc...

    White micas in carbonate-rich tectonites and a few other rock types of large thrusts in the Swiss Helvetic fold-and-thrust belt have been analyzed by 40Ar/39Ar and Rb/Sr techniques to better constrain the timing of Alpine deformation for this region. Incremental 40Ar/39Ar heating experiments of...

    The article presents information on disilicates. This group of silicates is characterized by an arrangement of the SiO[sub 4] tetrahedrons in a way that makes their closest grouping in a horizontal plane, closely locked sheets, giving the crystals a hexagonal or pseudohexagonal symmetry. In the...
