Abstract
<p>A review of the results of the complementary use of vibrational spectroscopy (infrared and Raman) and X-ray powder diffraction in the process of identification and spectra–structure correlation of some cyclo-, phyllo- and tectosilicate minerals originating from the Republic of Macedonia is presented. The following minerals are studied: schorl, Na(Fe<sup>2+</sup>,Mg)<sub>3</sub>Al<sub>6</sub>(BO<sub>3</sub>)<sub>3</sub>Si<sub>6</sub>O<sub>18</sub>(OH)<sub>4</sub>; beryl, (Be,Mg)<sub>3</sub>Al<sub>2</sub>Si<sub>6</sub>O<sub>18</sub>; chrysotile, Mg<sub>3</sub>Si<sub>2</sub>O<sub>5</sub>(OH)<sub>4</sub>; antigorite, (Mg,Fe<sup>2+</sup>)<sub>3</sub>Si<sub>2</sub>O<sub>5</sub>(OH)<sub>4</sub>; talc, (Mg,Fe<sup>2+</sup>)<sub>3</sub>Si<sub>4</sub>O<sub>10</sub>(OH)<sub>2</sub>; clinochlore, (Mg,Fe<sup>2+</sup>)<sub>5</sub>Si<sub>3</sub>(Al,Cr)<sub>2</sub>O<sub>10</sub>(OH)<sub>8</sub>; cymrite, BaAl<sub>2</sub>Si<sub>2</sub>O<sub>8</sub>×H<sub>2</sub>O; montmorillonite, (K,Ca)<sub>0.3</sub>(Al,Mg)<sub>2</sub>Si<sub>4</sub>O<sub>10</sub>(OH)<sub>2</sub>×nH<sub>2</sub>O; muscovite, KAl<sub>2</sub>(Si<sub>3</sub>Al)O<sub>10</sub>(OH,F)<sub>2</sub>; phlogopite, KMg<sub>3</sub>(Si<sub>3</sub>Al)O<sub>10</sub>(OH,F)<sub>2</sub>; biotite, K(Mg,Fe<sup>2+</sup>)<sub>3</sub>AlSi<sub>3</sub>O<sub>10</sub>(OH,F)<sub>2</sub>; sheridanite, (Mg,Al)<sub>6</sub>(Si,Al)<sub>4</sub>O<sub>10</sub>(OH)<sub>8</sub>; albite, NaAlSi<sub>3</sub>O<sub>8</sub>; microcline, KAlSi<sub>3</sub>O<sub>8</sub>; sanidine, (K,Na)(Si,Al)<sub>4</sub>O<sub>8</sub> and stilbite, Na<sub>3</sub>Ca<sub>3</sub>Al<sub>8</sub>Si<sub>28</sub>O<sub>72</sub>×30H<sub>2</sub>O.</p>
