Stratigraphic Correlation Research

[cngodles]

Hello,

 

I am searching for geologic time dates for some formations. Most are named in the 1800's, so the names may make no sense.

 

Europe

 

Maybe France?

• carboniferous limestone of borlton, County of La Couronne

 

Ireland,

• Lower Carboniferous Limestone, Ireland
• Calc carbonif Armagh?
• Formation and locality: Mountain Limestone, Armagh

 

England,

• Ticknall Formation, Mississippian, Ticknall, South Derbyshire, England
• carboniferous limestone around Bristol
• Carboniferous Limestone: Oreton, Shropshire.

 

United States

 

Kansas, USA

• Plattsmouth limestone, Oread formation, Virgilian, upper Pennsylvanian, in a quarry in northwestern Franklin County, Kansas

 

Indiana, USA

• Keokuk beds, Bono, Lawrence county, Ind. Clark and Harrison. counties

 

Illinois, USA

• Subcarboniferous (Keokuk); Illinois, Iowa
• Chester limestone, Chester and Pope county, Illinois.
  Worthen used the name Chester limestone for the same beds which Hall called Kaskaskia, but included this Chester limestone with the underlying sandstone in what he called the "Chester Group."
• In the limestone above coal No. 8, Upper Coal Measures; near Springfield, Illinois.
• In the upper beds of the St. Louis limestone; Alton, Illinois.

 

Pennsylvania, USA

• a stratum about one foot thick, black, carboniferous, and calcareous, head of inclined plane number 3 of the old portage railroad," which crossed the Alleghany Mountains from Hollidaysburg

 

Ohio, USA

• coal measures of Cambridge, Ohio. Limestone near Cambridge

 

Nebraska, USA

• Upper Coal Measures, Bennet's mill, near Nebraska City.

I dont understand.  If you know the names of the formations, just google them.  You'll find all the info you need.

That's the plan. I'm just looking for anyone who happens to browse the list and it's local to them and they know it. Some are very general, like Carboniferous Limestone of Ireland, so if I can find someone who knows it, I may be able to get more information.

For the US formations, use Geolex. Search for name of unit along with term Geolex.

 

Look for geological maps for each area in question.

 

You may need to find some charts that show the relationship between  local geological ages and the newer  international ones as shown in your chart. You could also search for info about a US age such as Virgilian.

I'll likely have some trouble. Right off the bat, a holotype for a species was found in the Chester limestone in Illinois. However, this was found within the Chester Group which seems to have a dozen limestone examples. Oui.
