GENERAL GEOLOGICAL NOTES ON THE COUNTRY BETWEEN 
OMEO AND LIMESTONE CREEK, COUNTY OF BENAMBRA. 
(NOS. 21, 22, AND 2.3 ON LOCALITY MAP.) 
By E. J . Dunn , A.U. 5 ., Director , Geological Survey. 
Omeo, by 1 aneroid, is about 1,900 feet above sea-level. From Omeo to 
Benambra Gap the road first passes over granitic rocks, and the highly 
inclined schists are met with at about 4 miles from Omeo. Benambra Gap 
is about 2,100 feet above sea-level. 
The folice of the schist are clearly defined, and it appears to be Silurian 
rock altered by contact with the granite. At Benambra and around Lake 
Omeo, which was quite dry at the time of our visit, the schist hills are 
remarkable for their beautifully rounded outline. From Benambra schistose 
rocks prevail for about 7J miles on the road to Mt. Leinster Station, 
which lies 12 miles E. 38 deg. N. from Benambra. Then granitic rocks 
continue to within about a mile of the station, where, at the homestead and 
to the north, a remarkable complex of agglomerate and igneous rocks was 
examined by Professor Skeats and myself. Some of the igneous rocks are 
intrusive in the agglomerate as dykes, and others as included masses. Pro¬ 
fessor Skeats has undertaken the task of describing the extremely varied 
and remarkable rocks that occur at this place.

From a sketch survey which I .made it appears that on the eastern 
boundary the agglomerate abuts against porphyry, which, gives place to 
granite within a short distance to the east. At the creek near the 
homestead, the height above sea-level is 2,400 feet, while the height of 
the highest point on the ridge where the agglomerate and porphvry meet, is 
2,800 feet, a vertical height of 400 feet of agglomerate. (See Fig. 32.) 
No trace of anything like bedding was observed in the agglomerate, which 
is an indiscriminate mixture of crystalline igneous rock fragments. The
