中文摘要 | 臺灣西南部「月世界」泥岩富含非膨脹性粘土礦物如高嶺石(26%)、白雲母( 19 %)及綠泥石( 14 %)。膨脹性粘土礦物幾不可測。 機械組成是砂粒 5 %、坋粒 60 %及粘粒 35 %; 而「玉井」泥岩則以初生礦物為主, 其中石英含量高達 60 %,鉀長石 17 %,機械組成是砂粒 32 %、坋粒 53 %、粘粒 15 %。此外,由於「月世界」泥岩 pH 值高於 85,因此含鈉量特高( 7.6cmol/kg )而其有機物含量特低( 0.85 %); 至於「 玉井」泥岩因其 pH 值低於 85,鈉含量較低。 |
英文摘要 | The mineralogical composition of the mudstone in the "Moon-world" of west-southern Taiwan predominates the non-expanding clay minerals, such as kaolinite (26%), muscovite (19%) and chlorite (14%). The expanding clay minerals are non-detectable. The mechanical composition contains 5% of sand, 60% of silt and 35% of clay. The mudstone in this area is very high in sodium (7.6cmol/kg) and low in organic matter (0.85%). Its pH value is higher than 8.5. The mudstone at Yuh-ching contains primary minerals such as quartz (59%), orthoclase (17%), goethite (5.2%), calcite (5.4%) and magnesite (6.5%). The mechanical composition of the mudstone contains 32% of sand, 53% of silt and 15% of clay. |
