A reef is a structure built by organisms that rises above the surrounding seafloor.: Reefs throughout geologic history share a common set of environmental are built in warm shallow seawater in the tropics and subtropics. Reefs occur only in waters that are relatively free of suspended, land-derived sediment, which allows sunlight to penetrate to the reef surface, permitting.

Stanley Keller. Reefs and reef structures are found across most of Indiana (Ault and others, in preparation), but reef structures commonly called pinnacle reefs have been recognized only in the Illinois Basin portion of Indiana.
This report outlinesbriefly the distribution and stratigraphic setting of reef structures in the Illinois Basin of southwestern Indiana and the structural highs associated with. Get this from a library. Silurian reefs in southwestern Indiana and their relation to petroleum accumulation.
[Leroy E Becker; Stanley J Keller]. From early pioneer times, quarries in northern Indiana, especially in the Wabash Valley, mined the reefs for roadstone and railroad ballast and burned the stone to make lime for mortar, agricultural lime, and whitewash. The reef rock was also used with other Silurian carbonate rock for foundation stone, flagging, and building stone.

Silurian reefs in northern Indiana were the focus of many studies that contributed substantially to reef models. During the last century, researchers explored a variety of aspects of Silurian reefs, including fossil content (e.g., Cumings and Shrock, a, b; Archer et al., ), petrography (Textoris and Carozzi, ; Simo and Lehmann, ), paleogeography (Droste and Shaver, Silurian reefs in southwestern Indiana and their relation to petroleum accumulation.

No matter how beautiful or scientifically unique a specimen is, it's value is limited without a variety of accompanying data that can be gathered only in the field.
Geology / Silurian Reefs. Just as you associate coal with rocks of Carboniferous age, many geologists will associate the Silurian with limestone. Much of the limestone was laid down in large reef systems or bioherms in similar environments to the huge coral barrier reefs of today. After the end of the Ordovician sea levels rose - probably due.

Classic works by Bretz (), Lowenstam, (,), Willman et al. (), and Ingels () were based entirely or In part on exposures at Thornton. The reef continues to be the subject of study as new exposures and subsurface data become available.
Exposures of Silurian reefs in Indiana. Bloomington, Ind. ( N. Walnut Grove, Bloomington ): State of Indiana, Dept. of Natural Resources, Geological Survey, (OCoLC) The Silurian Reef In the Silurian period, most creatures still lived in the sea, and the fossils from that time are nearly all of marine animals.
Near the shores of the continents, the waters were warm and shallow. There, great reefs, made up mainly of sponges, were able to grow.
The Marts field of Sullivan County, Indiana, is associated with a Silurian reef that is part of the Terre Haute bank on the eastern flank of the Illinois basin.
Gas production has come from Pennsylvanian sandstones at Marts field, and oil is presently being produced from limestones of the Devonian Muscatatuck Group.

A Silurian reef complex at Delphi, Indiana, consists of two subcircular reefs occupying an area of about 4 sq mi ( sq km). The reef is more than ft (62 m) thick, has a volume of about cu mi ( cu km), and effected as much as 75 ft (23 m) of compaction-induced.
In this example from southeastern Michigan, a successful oil well has penetrated a buried Silurian reef.
