- •
The efflorescence mineralogy showed a vertical distribution and changes over time.
- •
The mineral distribution is from interaction of RH diurnal changes and capillary flow.
- •
Over nine years the efflorescence developed after the intervention had reached the pre-intervention composition.
- •
Also simple salts, we found humberstonite, darapskite, konyaite and aphthitalite.
- •
Saline ions came mainly from groundwater and airborne particles.
