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。587Please respect copyright.ＰＥＮＡＮＡkDKvh3sQiC

(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。587Please respect copyright.ＰＥＮＡＮＡ8eXiD3kUmG

(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。587Please respect copyright.ＰＥＮＡＮＡGY3JOfANvc

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?587Please respect copyright.ＰＥＮＡＮＡEFh7c6BNW6
那就有待有心人上山採樣本發掘真相了。587Please respect copyright.ＰＥＮＡＮＡXGI37Wl3Xd
