Illinois State Geological Survey Building the Bedrock | ISGS

The sands deposited in those oceans became sandstone, and the formation of carbonate mud and the deposition of billions of marine organisms, such as shells, algae, and corals, formed limestone. The extensive beds of the Mississippian Period are more than 3,000 feet thick in some parts of Illinois and contain limestone deposits that hold large amounts of oil and fluorspar.

Limestone Bedrock Glade - Michigan Natural Features …

Limestone bedrock glade consists of an herb- and graminoid-dominated plant community with scattered clumps of stunted trees and shrubs growing on thin soil over limestone or dolomite. Tree cover is typically 10 to 25%, but occasionally as high as 60%. Shrub and herb cover is variable and there are typically areas of exposed bedrock.

Illinois' Industrial Minerals - Illinois State Geological ...

Illinois industrial minerals include rocks such as limestone, dolomite, and shale and nonmetallic minerals such as silica sand, clay, and fluorite.

Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

List of karst areas - Wikipedia

Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. It has also been documented for weathering-resistant rocks, such as quartzite, given the right conditions. This is an incomplete list of the major karst landscape areas of the world.

Trenton Limestone | Indiana Geological & Water Survey

Type locality and description: The Trenton Limestone was apparently named by Vanuxem (1838, p. 257) for rocks that were exposed at Trenton Falls in Oneida County, N.Y., and that were about 100 feet (30 m) thick. There is some confusion about what rocks were included in the Trenton by Vanuxem in his 1838 and 1842 reports, but they probably consisted of interbedded dark limestone and shale and a ...

What Do You Know About Joliet-Lemont Limestone ? - …

Laid down during the Silurian age, about 440-420 million years ago, JLL was formed in the same sedimentary process as other limestone. The difference is that Joliet-Lemont stone is chemically composed of calcium magnesium carbonate [CaMg(CO 3) 2] versus simpler calcium carbonate [CaCO 3].]. JLL is a true dolomite and not just limestone.
