초록

천연산 녹주석($Be_3Al_2Si_6O_{18}$, P6/mcc) 중 산출지가 각각 다른 아쿠아마린 시료인 녹주석-A, 녹주석-B를 물을 압력전달 매개체로 사용하여 고압실험 및 고온-고압실험을 실시하였다. 기존 문헌과 다르게 압력전달 매개체로 물을 이용했을 때 고압 및 고온-고압 상태에서 녹주석의 조성과 구조에 어떠한 영향을 주며 탄성 특성이 어떻게 변하는지를 확인하기 위함이다. 그 결과 녹주석-A, B의 체적탄성률은 각각 111(7) GPa, $K{_0}^{\prime}=73(7)$; 110(9) GPa, $K{_0}^{\prime}=65(8)$로 확인되었다. 이는 기존 연구에서 메탄올 에탄올 4 : 1 체적비로 혼합하여 관찰한 것과 다른 값 및 경향성을 보여주는 것으로 확인하였으며 관찰된 녹주석의 치밀화는 ICE VI, ICE VII 상변이 구간인 약 1.0 GPa, 약 2.5 GPa 구간과 일치하였다.

In-situ high-pressure and ex-situ high temperature-pressure experiments of natural beryl ($Be_3Al_2Si_6O_{18}$, P6/mcc) from two different localities (beryl-A and beryl-B) were studied using pure water as pressure transmitting medium. Compared to the previous study using a mixture of methanol:ethanol medium in 4 : 1 by volume, pressure- and temperature-induced chemical and structural changes under water medium are expected to be different. The derived bulk moduli are 111(7) GPa, $K{_0}^{\prime}=73(7)$; 110(9) GPa, $K{_0}^{\prime}=65(8)$ for beryl-A and beryl-B, respectively. We observe densifications in volume compression, which appear to be attributed to the phase transitions of water to ICE VI and ICE VII around 1.0 GPa and 2.5 GPa, respectively.
