Yes. You can make contributions to both a SEP and a Solo 401K Plan. In other words, a business can have both a SEP IRA and a Solo 401(K) Plan, although, there is generally no advantage for a business to have both active at the same time.
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.
Limestone, with its high calcium carbonate content, is easily dissolved in the acids produced by organic materials. About 10% of the earth's land (and 15% of the United States') surface consists of soluble limestone, which can be easily dissolved by the weak solution of carbonic acid found in underground water.arst topography can also be found extensively in the Shan Plateau of China, Nullarbor Region of Australia, the Atlas Mountains of northern Africa, the Appalachian Mountains of the U.S., Belo Horizonte of Brazil, and the Carpathian Basin of Southern Europe.
