where limestone is usually found
Best Answer: Limestone is a pretty common sedimentary rock type and is usually found in sedimentary sequences that were deposited in relatively shallow oceans. If you are in an area with sedimentary rocks, the odds are good that some of it is limestone. it is found in so many places that it is a bit of a ridiculous question to answer (too many answers). Just as examples, large areas of eastern north america on the inland (west) side of the Appalachians contain significant limestone in the near surface, and Florida is basically one big landmass of limestone.
