dc.description.abstract本文將討論由臺東向陽礦區不同地點所採集的雲母礦樣本之礦物組成、產狀和成因,在礦物組成方面藉由 X 光粉末繞射鑑定礦物種類和純度,並使用雷射粒徑分析儀分析其粒徑分布。依照野外產狀的觀察和礦物組成的結果可將本區白雲母礦分為三大類,第 1 類以區域變質作用為主,具有透鏡狀石英脈填充且劈理發達的白雲母片岩,表面經氧化過呈現黃色,顆粒度大且粒徑分布不平均,為本區成分最純的白雲母。第 2 類也屬於區域變質型,且劈理發達的白雲母片岩,以夾層型態夾在綠泥石片岩中,其白雲母的含量亦純,但含有少量的鈉鉀雲母和鈉長石,礦物顆粒較粗,粒徑分布較不平均。第 3 類為熱液蝕變或風化作用後形成的細顆粒絹雲母,其礦物成分與礦區開採後運送至選礦廠的樣品成分較為相近,含有綠泥石和少量方解石。石英在所有樣本中幾乎都有出現,經洗選過後的樣本石英含量明顯降低許多。長石多出現在第 1 和第 2 類區域變質作用類型。在第 3 類的熱液蝕變絹雲母中,長石含量幾乎消失,可能形成次生的葉蠟石。向陽公司目前開採的絹雲母樣本成分和第 3 類組成類似,以細顆粒的絹雲母為主,然洗選後的樣本仍含有少量的綠泥石和葉蠟石組成。en_US
