85 Rb + F , + 19 (1) where 0.3857 is based on the natural abundance ratio of 85Rb (0.721654) to 87Rb (0.278346) as defined by the Interna-tional Union of Pure and Applied Chemistry (IUPAC) (Meija et al., 2016). The raw 87Sr/86Sr ratio is calculated from the signal ratio of 87Sr19F+to 86Sr19F+, as expressed in eq. (2).

Mineral mika dibezakan oleh belahan basalnya yang sempurna, yang bermaksud bahawa ia mudah dipecah menjadi kepingan nipis, selalunya telus. Dua mika, biotit, dan muskovit, adalah sangat biasa sehingga dianggap sebagai mineral pembentuk batu . Selebihnya agak jarang berlaku, tetapi phlogopite adalah yang paling mungkin dilihat di lapangan.

MICA. O grupo de minerais mica é composto por diversos minerais do grupo dos filossilicatos. Sua classificação de cor é considerada alocromática devido a sua variedade de cores (branca, preta, marrom, roxo, verde). Sua dureza na escada de Mohs é de 2 a 4. Os principais minerais deste grupo são: Biotita, moscovita, lepidolita, flogopita

Os minerais de mica distinguem-se pela sua clivagem basal perfeita, o que significa que são facilmente divididos em folhas finas, muitas vezes transparentes. Duas micas, biotita e moscovita, são tão comuns que são consideradas minerais formadores de rocha . O resto é relativamente incomum, mas a flogopita é a mais provável de ser vista

· Abstract. Mica (i.e., muscovite and phlogopit) are platelet-shaped reinforcing fillers used for increasing heat deflection temperature and reducing warpage in polymers. Mineralogically the mica group consists of phyllosilicates all with monoclinic crystal structure and perfect basal cleavage. Micas are muscovite (typically white to gray

· The analyzed mica products are special compared to other muscovite mica minerals because the deposit contains unusual finely distributed, delaminated mica particles. Table 3 summarizes the behavior of a series of non-surface-treated muscovite mica products in polypropylene at 20 % filler load.

Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.
