THE GEOLOGY OF LIMEKILNS, BATHURST DISTRICT. 291 



the variegated variety, which is all that has hitherto been quarried, 

 and it will be used in that sense in this paper. 



Preparations are, however, being made to open up quarries in 

 some of the other beds, and it is likely that the name of Fernbrook 

 marble will eventually be used to denote all the ornamental stone 

 obtained from the Limekilns area. This appears to be desirable, 

 since Fernbrook is a more euphonious name and also more 

 definite than Limekilns. Leaving Limekilns for a time, we find 

 no more limestone for a considerable distance, but near Green 

 Swamp, about twelve miles south, there is a small bed, and there 

 are also one or two others in the neighbourhood, all on the same 

 line of country. Taking a line more to the west, the rocks in all 

 cases striking nearly north and south, we find, near Wyagdon, a 

 very fine, close grained marble, pure white with greenish or black 

 veins (No. 12). This stone has been obtained as yet only at the 

 surface, but promises well, if opened up. It dies out if followed 

 south before reaching the granite, but on the other side of 

 Bathurst, near the old copper mining centre of "Cow Flat," 

 there is a similar but coarser grained marble, white with bluish 

 veins (No. 13). These marbles, being situated on what appears 

 to have been the axis of greatest metamorphism of the district, 

 have been completely altered, and are never likely to yield fossils. 



Proceeding still farther south, however, we find at Pockley, 

 about twenty-two miles from Bathurst, a very rich limestone 

 country. Some beds are crinoidal and make a very ornamental 

 stone when polished (No. 16); other beds are ordinary bluish 

 limestone of no particular beauty, but about a mile from the 

 township, at a place called Jumper's Flat, there is a saccharine 

 marble of a warm cream colour (No. 15). This is a very pretty 

 stone, but does not appear to have been utilised except to a limited 

 extent for lime burning. Beyond Rockley, again to the south, a 

 magnesian limestone occurs at Bunnamagoo. This rock appears 

 at first sight to be a coarsely crystalline ordinary limestone, but 

 it does not effervesce in cold acids, and may be classed as a 

 dolomite (No. 17).
