I use this site https://mrdata.usgs.gov/geology/state/map-us.html#search-results to see what formations my collecting sites are in. But, due to my lack of knowledge (?) it only helps so much.
When I click on the map at the collection site location I get this type of data :
Record ID
Name
Comment
OHOdl;0
Drakes, Whitewater and Liberty Formations, Undivided
Ordovician
OHOgm;0
Grant Lake and Fairview Formations, Miamitown Shale, Undivided
Ordovician
OHOwa;0
Waynesville and Arnheim Formations, Undivided
Ordovician
I interpret this to mean that all 3 formations are represented at this site. In this case, standing at the site I can visibly discern 2 very different areas, one above the other. But that isn't typically the case.
Can anyone give me some guidance or point me in the direction of how to interpret this information? Is there a better place to go to figure out the formations?
