IRON ORES OF THE CARTERSVILLE DISTRICT, GEORGIA. 
By C. W. Hayes and E. C. Eckel. 
One of the most productive iron-ore districts in the Southern 
Appalachians lies in the vicinity of Cartersville, Bartow County, Ga. 
The ore deposits of this region are so directly related to the stratigra- 
phy and structure of the area that a brief description of the geologic 
features must be given before taking up the subject of the origin and 
position of the ore deposits. 
GENERAL GEOLOGY. 
Stratigraphy. — The area in question occupies the southeastern half 
of Bartow County, Ga. Its surface is about equally divided between 
the older crystalline and metamorphic rocks which occupy the Pied- 
mont Plateau and Appalachian Mountains in the east, and the unal- 
tered Paleozoic formations which occupy the Appalachian Valley on 
the west. The line of separation between these two groups of forma- 
tions in the Cartersville district is located as follows: Beginning at the 
north, it lies about half a mile east of Fairmount post-office, and 
runs almost due south for about 7 miles, when it swings eastward to 
near Martins Mill. From this point it takes a southwest direction, 
passing half a mile west of Rowland Springs, and then turns south- 
east, crossing the Etowah near the old iron works and crossing the 
railroad about a mile southeast of Emerson. From the point at 
which it crosses the railroad the line pursues an almost southerly 
direction for a few miles; then turns northwest, almost reaching the 
Etowah at the Free Bridge, 4 miles from Cartersville, and finally 
turns southwest, passing about 2 miles south of Stilesboro and Tay- 
lors ville. 
As noted later, this line between the two groups of formations 
marks, throughout most of its extent, the position of the Cartersville 
fault, which is the most important structural feature of the region. 
The formations of the valley belt, to the west or the Cartersville 
fault, are, in ascending order, the Weisner quartzite, the Beaver 
limestone, the Rome and Conasauga shales, and the Knox dolomite. 
All, except the latter, belong to the Middle and Lower Cambrian; and 
the lower portion of the Knox dolomite should probably also be classed 
with the Cambrian. The principal outcrop of the Weisner quartzite
