"The etymology of Aksai Chin is uncertain regarding the word "Chin". As
a word of Turk origin, aksai literally means "white brook" but whether
the word Chin refers to Chinese or pass is disputed. The area is largely
a vast high-altitude desert including some *_salt lakes_* from 4,800
metres (15,700 ft) to 5,500 metres (18,000 ft) above sea level. It
covers an area of 37,244 square kilometres (14,380 sq mi)."
http://en.wikipedia.org/wiki/Salt_lakes
"A salt lake or saline lake is a landlocked body of water which has a
concentration of salts (mostly sodium chloride) and other dissolved
minerals significantly higher than most lakes (often defined as at least
three grams of salt per liter). In some cases, salt lakes have a higher
concentration of salt than sea water, but such lakes would also be
termed hypersaline lakes. A salt lake that has a high content of sodium
salts, especially chlorides and *_sulfates_*, is sometimes termed a soda
lake."
This did ring a bell to me, as I remember that during experiments
conducted in chemistry-class, Copper-sulfate (CuSO_4 ยท5H_2 O) creates
crystals with a *_blue_* color while a solution of Copper-nitrate
(Cu(NO_3 )_2 )has a *_green_* color and also creates crystals with a
*_blue_* color.
This could very well explain the blue-ish/greenish areas in these links
http://g.co/maps/375xc and http://g.co/maps/73s5d
In the areas in the second link I wouldn't be surprised at all when
these are used to "harvest" Copper-sulfate/nitrate and during a special
"drying" process the Copper is extracted.
