- 文章：漫步將軍澳(二)貝殼之島
- 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！！
