淡水的绿松石天蓝色的颜色外观的身体是很好地解释和例子Kumar的在2016年的一篇论文,题为“[* *研究绿松石和明亮的天蓝色的出现淡水身体* *][1]”。在这篇文章中,作者解释了导致淡水的蓝绿色色调的深浅发现世界各地的机构,提出一个分类/分类的淡水。作者分类不同的绿松石蓝色出现淡水的身体分为两类:1)自然2)人为这样的水体因素自然起源的“自然”和因果因素下非天然的起源(人为)被放置在“人为”类别。“自然”范畴进一步细化分类分为三个子类:a。冰川美联储(溪流、湖泊似乎绿松石蓝色由于散射光的冰川面粉(石粉),除Phoksundo湖(尼泊尔),冰碛湖(加拿大),等等。b。火山热液:在火山地区的湖泊和河流,水热也出现蓝绿色的天蓝色的起源。例如,kawah Ijen(印度尼西亚),Yudamari湖(日本),出现蓝色由于散射粒子从硫酸亚铁。里约热内卢天蓝色的另外一个在哥斯达黎加人中河出现蓝绿色从铝硅酸盐粒子散射的结果。c。碳酸钙丰富:碳酸钙丰富的淡水的身体也出现蓝绿色的天蓝色的从悬浮的方解石颗粒散射的结果。例子,Havasu溪(大峡谷),熊湖(犹他州),特湖(克罗地亚)。2。 Anthropogenic : The author has discussed two water bodies appearing turquoise to sky-blue. Lukha river (Wah Lukha) which flows in meghalaya (India) turns turquoise every year in winter season, real cause not known but coal and limestone mining cited as a reason. Wilge river (S Africa) flows in coal mine affected area appears turquoise and aluminium has been cited as causing agent. I would recommend reading the paper if you are interested in getting a deeper understanding. Picture 1. Different Glacial-fed freshwater bodies. 2. Calcium carbinate rich freshwater bodies. 3. River appearing turquoise as result of anthropogenic activities.
