Humans have exploited karsts for a variety of products and services, but unsustainable practices have caused population declines and extinctions among siteendemic taxa. Limestone quarrying is the primary threat to karst biodiversity in Southeast Asia, where quarrying .
Limestone is less resistant than most igneous rocks, but more resistant than most other sedimentary rocks. It is therefore usually associated with hills and downland, and occurs in regions with other sedimentary rocks, typically clays. Karst topography and caves develop in limestone rocks due to their solubility in dilute acidic groundwater.
Nov 01, 2016· The erosion of limestone has formed the spectacular karst landscape in Krabi and Phang Nga Bay (once coral reefs hundreds of millions of years ago) due to the chemical weathering where acid rain, which produces carbonic acid, has dissolved layers of soluble bedrock.
The bedrock underlying this general area is limestone, which dissolves in weak acids, such as those in rainwater. Sinkholes are formed when large circular caves in the limestone collapse. The small group of sinkholes in NE Lower Michigan is only part of a larger karst system extending eastward to Lake Huron.

subsidence from dewatering when excavating below the water table at limestone quarries. The term "limestone" applies to any carbonate formation where the development of karst features can occur, and the investigation is required when an operator proposes a new pit or any expansion that will advance below the water table.
