Deposit FRESH WATER EVAPORATION RATES ARE ABOUT 3000 MM/YR AND RAINFALL IS ABOUT 12.5-25 MM/YR. TEMPERATURES RANGE FROM FREEZING TO 24 DEG C IN JUNE (WINTER) AND 9 DEG C TO 35 DEG C IN JANUARY (SUMMER). SEE MRDS RECORD I000504: SALAR DE ATACAMA-SOCIEDAD CHILENA DE LITIO. ; INFO.SRC : 1 PUB LIT
Deposit LIMESTONE IS MASSIVE AND WHITE. THE BARRA HONDA LIMESTONES CROP OUT IN A SERIES OF ISOLATED KNOLL-LIKE HILLS AROUND THE HEAD OF THE GOLFO DE NICOYA IN A TRIANGULAR AREA BETWEEN NICOYA IN THE WEST, COLORADO IN THE EAST, AND STRETCHING NORTHWARDS ALMOST TO LA GUINEA.
Deposit THE SALAR COVERS AN AREA OF 3000 SQ KM AND HAS A SALT NUCLEUS COVERING 1400 SQ KM. THE TOTAL SALT THICKNESS EXCEEDS 400 M. THE TOP 30 M ARE POROUS AND IMPREGNATED WITH BRINES. SEDIMENTS OCCUPY THE NORTHERN HALF OF THE SALAR, BECOMING FINER TOWARDS THE SOUTH. K, LI, AND B ARE CONCENTRATED IN THE SALAR. THE SULFATE CONTENT IS HIGHER IN THE NORTH AND THERE IS AN AREA OF HIGHER CALCIUM CONTENTS TO THE SOUTH. THE BRINE CHEMISTRY IS SUCH THAT MURIATE AND POTASH SULFATE CAN BE PRECIPITATED SEQUENTIALLY. THE DRAINAGE BASIN OF THE SALAR EXTENDS OVER AN AREA OF 13,300 SQ KM. THE LITHIUM CONCENTRATION AT ATACAMA IS 7 TIMES THAT AT SILVER PEAK, NEVADA.
