That sulfate minerals is minerals containing the so4 2- radical, formed by precipitation from water. the most common are the anhydrous and hydrated calcium sulfates, anhydrite (caso4) and gypsum (caso4.2h2o). sulfates are deposited as a generally minor component of most carbonate successions, but due to their high solubility they may not survive subsequent dissolution by ground water. even if they survive subsequent dissolution by ground water. even if they survive at depth, they tend to dissolve as they are raised nearer to the surface following uplift and erosion of overburden. removal of sulfates by dissolution may contribute to the early establishment of secondary permeability in limestone sequences. sulfate solutions have a limited corrosional effect upon calcium carbonate, but may also be oxidized to produce sulphuric acid, which is highly corrosive of limestone.?

Palaeokarst in the Noondine Chert in Southwestern Australia: Implications for Water Supply and the Protection of Biodiversity
Abstract:

In southwestern Australia, karst features occur in geological formations other than the coastal calcarenites of the Tamala Limestone. The Noondine Chert was formed by the silicification of carbonate rocks and contains relict carbonate textures and palaeokarst features such as intense brecciation and the presence of subsurface voids. This geological formation is an important aquifer to the east of the Perth Basin where groundwater resources are otherwise limited, and the aquifer is highly vulnerable to contamination from agricultural land use. The Noondine Chert may also contain a rich stygofauna. This has not been taken into account in groundwater protection policies, and needs to be assessed as a matter of urgency.
