當湖水或海水受到藻類或微生物感染的時候，水的顏色便會變成紅色一片。395Please respect copyright.ＰＥＮＡＮＡWehFxI0WOr

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。395Please respect copyright.ＰＥＮＡＮＡ9aMbhFqrVb

(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。395Please respect copyright.ＰＥＮＡＮＡ1ITeAtxjUC

該湖泊海拔5060米高，低氧、高紫外線及寒冷集於一身，冬天平均溫度攝氏-16，夏天平均溫度攝氏-6。395Please respect copyright.ＰＥＮＡＮＡVRHywg9KGc

(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。395Please respect copyright.ＰＥＮＡＮＡ9aoNuTfZMA

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?395Please respect copyright.ＰＥＮＡＮＡja0O6aVxs8
那就有待有心人上山採樣本發掘真相了。395Please respect copyright.ＰＥＮＡＮＡgx9NIWY4e1
