What you are doing is defining a type of sedimentary rock as 'sandstone' even where the grains of sand/silica are glued together with calcium carbonate.
Sandstone glued together with silica is a tad different ~ if you've ever been to Wausau Wisconsin you'd see a ginormous outcropping of the stuff ~ a glacial movement during the last peak period transported much of that mountain to Northern Indiana and Ohio ~ we had a bunch of it in the backyard of the home where i grew up. That was not glued together with calcium carbonate. BTW, disturbingly, I've found some of the same rock here in Northern Virginia so that'd be a glacial period BEFORE the Appalachians rose ~ probably the Snowball Earth period ~ just thinking of the size of an 800 mile long glacial flow.
Back to OK, the three areas you identified as having limestone are simply areas where there is currently active mining, mostly for crushed rock. Over in Indiana that quality of stone is usually turned into portland cement. However, in commercial grades of building limestone, you are going to find that some fine grained early ~ pre-life ~ limestones look to have sand in them.
Looking over the OK soils maps ~ of interest to agriculturalists if not geologists ~ there doesn't seem to be a lot of wind blown loess like you find further North, but there are 'sand hills' ~ in places.
When I look at this map ~ http://tapestry.usgs.gov/ages/carboniferous.html - I see Pennsylvanian limestone, and then coal, in NAWTHAN OKLAHOMA! There are other limestones to the Souf!
My sister lives there, and she and I spoke on the phone tonight. It was close as she lives in Bethany.
I am just so sad — our nation is just plagued by tragedy after tragedy, so many affecting children. Lately I feel as if I don’t want anyone in my family to ever walk out the door anymore.
Prayers for these parents — may God comfort them in this tragic time.
Just wondering ... since it seems you have knowledge of this subject. Would it be possible to put in storm cellars/shelters/basements if you were willing to spend the money & time and BLAST out the basement before building on top of it? Today’s tragedy makes it obvious it would be a good thing for everyone in Tornado Alley (including schools and other large buildings) to have a shelter to run to.
