The foot-wall consists of a horn-stone-like Cretaceous limestone. In regard to their composition also,there exists a great similarity between the Tennessee and Appalachian 850 ORE-DEPOSITS ores. The principal places o£ production are Kusselville, Mannie, andGoodrich. It is Ukely that a portion of the ores found in the Ozark uphft belongto this class, this uphft being the dome-hke group of hills, almost 2000 height, occupying the southern half of Missouri and a narrow strip LenistcrtynLunestone hornstone like3rown hornstone like Shale Ore Monterey OanJjbmeBlue Shale RomneyMarl.

The basement is formed ofArchaean and Algonkian porphyry and granite, overlaid by Cambrian,Silurian and, in the south-west of the district, also by Lower deposits occurring here in Carboniferous limestone are regardedas of metasomatic formation, their iron content having percolated fromthe Cambrian and Silurian beds into the Carboniferous hmestone. Thesedeposits do not appear to be of any great economic importance. THE MANGANESE LODES As already stated,^ anjd re-stated when discussing the sedimentation ofthe iron- and manganese deposits,^ iron and manganese have chemicallyand geologically many properties in common, such for instance as the factthat the small amounts of both metals contained in the rocks go fairly readilyinto solution.
