Geocharacteristics and medical value of carbonate geothermal water in downtown Chongqing
Objective To study the physical and chemical characteristics and medical effects of carbonate geothermal water in downtown Chongqing.Methods Thedataofphysicalandchemicalcharacteristics of carbonate geothermal water in downtown Chongqing was collected and analyzed by field testing
sampling and laboratory testing.Results The temperature of geothermal water of research area was 24.5
