Abstract

関東山地において,ひすい輝石+石英組合せを持つ岩石を新たに発見した。この岩石は第三紀の栃谷層と断層関係にある超塩基性岩とともに露出している。この岩石は,ひすい輝石+石英組合せが安定な変成作用(高圧条件)と,アルバイト+エジル輝石が安定な変成作用(中圧条件)の2回の温度圧力条件を記録している。

Jadeite+quartz rocks are newly found in the Kanto Mountains, central Japan. It is associated with ultramafic rocks which are in fault contact with the Tertiary Tochiya Formation. Two metamorphic stages are recorded in the rock: the high pressure jadeite+quartz stage and the medium pressure albite+aegirine-augite stage.
