而除了藻類感染之外,大自然間亦有著長年累月呈紅色的湖泊。312Please respect copyright.PENANAtbOx6ZEFQp

(圖2)在喜馬拉雅山脈位置34°0.280′N 76°43.295′E,就有著一道長年累月均為棕紅色的湖泊。312Please respect copyright.PENANAw8J7B38abA

(圖3)紅湖的形成,相信是由於湖水含有高濃度的氯氣,與周遭岩石的鐵離子產生化學反應,形成棕紅色的針鐵礦 (Goethite)及赤鐵礦 (Hematite)等。312Please respect copyright.PENANAw2d92HnofP

但是紅湖的不遠處有著藍色的湖泊,為何它又不會呈棕紅色的呢?312Please respect copyright.PENANACJwcKCtpnb
那就有待有心人上山採樣本發掘真相了。312Please respect copyright.PENANAVw4q8azBe3
