文摘
- •
Resistivities are low for coarse grained gypsum and high for finer grained gypsum.
- •
Resistivity–lithology relationship is controlled by fracturing and water content.
- •
Gypsification and karstification occur mainly within massive coarse grained gypsum.
- •
The impermeable bedrock represents the edge for gypsification processes.
- •
Karst isn't restricted to the residential area, nor only in the first 30 m in depth.
