    • GDESC:　　標本RM06-021為變質砂岩，屬於矽質的區域變質岩，為砂岩受到輕度的變質作用所形成，與石英岩不同的地方主要在於其石英含量較低。
      　　變質砂岩之礦物組成及顏色與砂岩相似，常見礦物為石英、長石、雲母及方解石，有時亦可發現鋯石、磷灰石、磁鐵礦或黃鐵礦等礦物，此外可能含有經變質作用產生之石墨或綠泥石等礦物。砂岩與變質砂岩經常是漸變關係，有時兩者之分界不易確定，但變質砂岩之礦物顆粒一般於壓力下再結晶而變得較大，此外變質砂岩因壓力作用而具有特定的礦物排列或構造方向，質地較為緻密且堅硬。
      　　變質砂岩於臺灣本島的分布廣泛，主要位於中央山脈地區，相關岩層包含廬山層、四稜砂岩、八重溪層、樟山層、禮觀層及石洞層等。
      　　於應用上，變質砂岩因其堅硬特性於傳統上被作為建材，此外在近代也是工業上玻璃、陶瓷、研磨及冶金助溶劑等領域之重要原料。
      　　本標本之原產地不詳，標本長寬約10 x 9公分，呈現長方形的緻密塊狀，結晶顆粒細緻，顏色為灰色並帶有部分灰褐色緻褐色的外層。
