The temperature derivatives of  v  p  (∂ v  p /∂ T ) and  v  s  (∂ v  p /∂ T ) show a discontinuous change at ~400 °C. The ∂ v  p /∂ T  is −0.9 × 10 −4  km/s/°C below 400 °C and −4.4 × 10 −4  km/s/°C above 400 °C. The ∂ v  p /∂ T  also increases from −0.7 × 10 −4  to −4.1 × 10 −4  km/s/°C. These  v  p  and  v  s  show reversible changes between 25 and 700 °C. In contrast, both  v  p  and  v  s  increase (0.08 and 0.08 km/s, respectively) at 700–800 °C, and show irreversible changes after heating to 800 and 900 °C. The X-ray powder diffraction analysis shows that the run product heated to 900 °C shows a higher lattice angle γ than the run products obtained on heating up to 700 °C, which is comparable to the lattice angle γ of high and low plagioclase, respectively. We ascribe the discontinuous change in  v  p ,  v  s , ∂ v  p /∂ T , and ∂ v  s /∂ T  to the order-disorder transition of plagioclase at high temperatures."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380848661729548545","@type":"Researcher","foaf:name":[{"@value":"Y.
