262 MAGNETIC IRON ORES OF VICTORIA COUNTY. 
The occurrence of labradorite rock or norite, which is found at the 
Miles Location, and titaniferous iron beds, which occur at Pine Lake 
and other places, would seem to point to the norian or upper lauren- 
tian of Logan, but there is not a universal enough development to 
justify such a conclusion. 
To the East of Kinmount the gneiss is replaced by crystalline 
limestone, in which rock the Victoria, or Old Snowdon, mine occurs. 
Continuing Eastward, between the Victoria mine and the Howland 
and Ledyard locations, the road is very circuitous, and not on the 
map, therefore my observations of the rocks might be misleading as 
to their actual occurrence. Halfway between the Snowdon and Ledy- 
ard locations, quartzite and a fine grained pinkish syenite take the 
place of limestone. The crystalline limestone appears again before 
arriving at the Ledyard location, and continues westward beyond the 
Howland property further than I went. 
In the Ledyard property there is a band of dioritic rock (doleritic 
in places), in which are the iron occurrences found in that property. 
Coming back to Kinmount, and then going in a westwardly direc- 
tion, the gneiss is replaced by a band of crystalline limestone a 
mile wide, which again is immediatety succeeded by gneiss and 
syenite. 
Not far from the limestone the Paxton mine is in a syenite gneiss, 
with narrow beds of crystalline limestone occuring in places both 
above and below the ore 
From Kinmount North the general character of rocks is precisely 
the same as already mentioned, granite, gneiss, syenite and crystalline 
limestone. The geological features of that part of the country which 
T saw are precisely the same as the Madoc region, with the exception 
of a stronger development of the dioritic ridges in the Madoc region. 
In this district, hornblendic pyroxenic rock and erystalline lime- 
stone are, as a rule, associated with the iron ore. In the Madoc district 
the Hematite mine is an example of the intimate connection of the 
iron ore with crystalline limestone, while the Seymore mine is an 
example where that rock is wanting. 
From the accumulation of instances, however, it would seem that in 
searching for iron ores, especially in the Victoria district, it would be 
well to keep in the vicinity of the bands of crystalline limestone, for 
as a rule the ores occur both in it and near its junction with granite, 
hornb!endic and pyroxenic rocks.
