- 作者:大野狼(julienbike)
很多人到澎湖都會到藝品店購買文石,通常都是印章。澎湖生產優質文石,其中以將軍生產的優質文石最負盛名。將軍 產的文石並不是一般作為印章用的文石,而是作為寶石,以及作為藝品類的文石。將軍文石有兩大特點:一是有同心圓狀的 眼;另一是具有十分討喜的金色同心圓。
今天來跟大家分享在這文石之島上,文石是多麼的普遍。文石的成因跟火山爆發有關,澎湖的玄武岩依照岩漿的性質而 分可以分為兩類:鹼性玄武岩和矽質玄武岩,而依照型態則可分為緻密玄武岩和多孔狀玄武岩。其中鹼性玄武岩顏色深黑而 極堅固,在澎湖數量不多,七美的玄武岩就是屬於這種。這種玄武岩因為他的質地緻密而通常屬於緻密玄武岩,也因為這樣 的特性所以是不會產生文石的,因此七美沒有產文石。另一種蜂窩狀玄武岩,顧名思義內部就充滿了像蜂窩般的孔洞,文石 就是產生在這類的玄武岩中。
文石是如何在玄武岩中形成的呢?這有兩個原因,一是潮汐的影響,海水中充滿的礦物質,在孔洞中堆積結晶,久了就 成為色彩多變的文石。但是這樣的影響僅止於潮間帶,可是文石的產地並不是僅在潮間帶上。而這就要談到冰河期了,因為 澎湖的高度低,因此多次的冰河期產生了海進海退,澎湖就有時在海面下,有時在海面上,因此產生了大量的文石礦。
目前文石是禁止開採的,所以其實想購買到真正澎湖產的文石是相當不容易的,大多都是以前開採保留下來的,而低價的文石則多是進口的了。既然將軍是優質文石的產地,所以文石其實是隨地可見的,只不過這些大多不具商業價值因此才能保留到現在。在將軍的海邊到處走走看看,偶爾也能發現一些美麗而有趣的文石礦石,不過記得喔!別把他帶走!!
