上回我們終於找到化石中有黃金的標本;最近又有礦物界朋友問我:有沒有金礦又是螢光礦物?這件事我早就在注意,並且用紫外燈試了幾百個標本,以及最近寄來最可能是螢光礦物的兩件標本:
〈一〉碲金礦含自然金母岩是螢石:
Strong Mine, Cripple Creek District, Teller Co., Colorado
3.72cm x 3.66cm x 2.16cm
A terrific example of calaverite from this classic locality!!! This specimen consists of the characteristic matrix that hosts numerous striated prismatic crystals partially included in the matrix!!! The crystals have a particularly golden-silver hue in person and, upon close examination, appear to host some partial native gold pseudomorphs (best viewed with a loupe or scope)!!! The matrix itself hosts a distribution of microcrystals as well!!! The fluorite has lively purple color and there are some curious square-shaped marks (quartz replacing fluorite?) present as well!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!!
〈二〉自然金母岩是方解石:
Val d'Or, La Vallée-de-l'Or RCM, Abitibi-Témiscamingue, Québec, Canada
2.88cm x 2.46cm x 1.45cm
A fantastic example of native gold from Canada!!! This specimen consists of a rich showing of complexly crystalline native gold protruding from calcite matrix!!! The gold has a brilliant, lively yellow hue!!! This specimen retains an old Howard Belsky dealer label (c.1980) as well!!! The pics hardly do it justice!!!
照射的結果,與我原本的金礦有螢光反應的都相同,均為暗紫色螢光反應,希望以後可以找到螢光
更為光鮮亮麗的金礦標本。
