Abstract

The green tourmalines from Kayah state, Myanmar were investigated by WD X-ray fluorescence, UV-vis, and mid-infrared spectroscopy for comparison to tourmalines of other deposits. The group of tourmaline was calculated and classified by chemical analysis. The samples belonged to the Calcic group and Uvite. The green tourmalines showed a strong absorption band at 415 and 611 nm. The presence of $V^{3+}$ ions is responsible for these absorption bands. Combination of the stretching and bending mode by the vibration between cationic and hydroxyl units (metal-OH) are observed in the 4600 ~ 4200 $cm^{-1}$.

미얀마 Kayah산 녹색 투어말린의 특성을 X-선 형광분석, 자외선-가시광선 그리고 중적외선 분광분석을 통하여 타산지의 녹색 투어말린과 비교하였다. 화학성분 분류에 의해 미얀마 투어말린이 속한 그룹을 조사 하였다. 미얀마 투어말린은 V 원소를 많이 함유하고 있었고 X 사이트에 Ca 원소를 반 이상 함유한 Calcic 그룹에 속했고 우바이트 (Uvite)로 명명되었다. 자외선-가시광선 분석결과 $V^{3+}$ 이온에 의한 415와 611 nm에 강한 흡수밴드가 나타나 녹색 투어말린의 원인이 되었다. $Fe^{2+}$ 이나 $Cu^{2+}$ 이온에 의해 녹색이 나타나는 타산지의 녹색 투어말린과 차이가 있었다. 중적외선 분석에서는 수산기와 금속들 간의 진동에 의한 흡수가 일어났는데 1100 $cm^{-1}$ 근처에서 스트레칭 모드, 3500 $cm^{-1}$ 주변에서 벤딩 모드 그리고 4600과 4200 $cm^{-1}$ 사이에서 스트레칭과 벤딩 모드의 혼합 밴드가 나타났다.
