초록

감람석은 맨틀 상부의 주요 광물이고, 탄성적으로 매우 비균질하다. 맨틀암석이 고압고온에서 변형될 때, 이러한 감람석이 배열되어 격자선호방향(LPO, Lattice Preferred Orientation)이 형성된다. 감람석의 격자선호방향은 압력, 응력, 그리고 감람석 내부의 물(OH)의 양에 따라 크게 영향을 받을 수 있다. 이 논문에서는 물, 응력, 그리고 압력이 어떻게 감람석의 격자선호방향(LPO)의 형성에 영향을 주는지에 대해 그동안 발표된 논문들을 리뷰했고, 자연 맨틀암석에서 발견된 감람석의 격자선호방향들을 요약했으며, 감람석의 격자선호방향과 맨틀상부에서 나타나는 지진파의 비등방성과의 연계성에 대해 토의하였다. 그리고 최근에 맨틀암석에서 발견된 사방휘석의 네 가지 격자선호방향들을 기술하였다.

Olivine is a dominant mineral in the upper mantle and is elastically very anisotropic. When olivine is deformed under stress at high pressure and high temperature, lattice preferred orientation (LPO) is formed. It is known that the LPO of olivine is affected by water, stress, and pressure. In this paper, I reviewed the papers dealing with the effects of water, stress, and pressure on the LPO of olivine, summarized the papers on the LPOs of olivine in natural mantle rocks, and discussed its implications for seismic anisotropy in the upper mantle. In addition, I also described four types of LPOs of orthopyroxene recently found in natural spinel lherzolite.
