dc.description.abstract矽孔雀石藍玉髓為臺灣本土最知名的寶玉石品種,因其美麗的綠藍至藍綠色澤,也被業界尊稱為"臺灣藍寶"。世界各地藍玉髓多以斑岩銅礦副產物之形式產出,由熱液作用帶來隱晶質二氧化矽,混合矽孔雀石為主的一系列含銅礦物,而其美麗色澤即起因於矽孔雀石微包裹體。臺灣藍玉髓主產於海岸山脈都巒山層的安山岩與火山角礫岩中,藍玉髓以透鏡狀體產於圍岩裂隙或破裂帶內,玉髓脈周圍也因後期熱液換質作用而產生綠鱗石化或黏土化。受限於礦業法規,臺灣本土礦場受到嚴格的管制,開採的環境成本日增且產能有限,造就了臺灣藍玉髓的高昂身價。隨著寶石市場需求日增,進口藍玉髓以臺灣藍寶之名銷售已對本土產藍玉髓產生衝擊。因應產業之需求,本研究對七個產地的藍玉髓樣本進行一系列礦物及地球化學分析,樣本分別來自於臺灣-都蘭山寶豐祥礦場1號坑(Bao-Feng-Xiang)、美國-亞利桑那州靈感礦(Inspiration mine, Arizona, U.S.A.)、美國-亞利桑那州雷礦(Ray mine, Arizona, U.S.A.)、秘魯-皮斯科百合(Lily mine, Pisco, Peru)、秘魯-阿雷基帕(Arequipa, Peru) 與印尼-卡西魯達島(Kasiruta Island, Indonesia)、墨西哥-澤卡特卡斯(Zecatecas, Mexico)等七個產地,希望透過礦物組成或地球化學特徵等,區別臺灣與其他產地藍玉髓的差異,作為未來業界藍玉髓產地鑑定之可行性評估。初步結果顯示,不同產地之藍玉髓在礦物組成上,可能透過斜矽石含量加以區分,印尼產藍玉髓平均斜矽石含量最高,墨西哥澤卡特卡斯礦則是平均最低,幾乎不含斜矽石;部分產地之藍玉髓在地球化學特徵上有明顯差異,以臺灣寶豐祥藍玉髓為例,相較於其他產區具有高錳、高鈾與高鉀的趨勢。en_US
