Mitchell's Quarry. — This has other names — Hongkong 

 quarry and Gollans quarry ; the latter is the original name. 

 It is about a half mile further out than the quarry in Gunn's 

 Paddock, and is near Campbell's Gully. This stone has been 

 used for the Convent (1892), and also for the additions 

 in 1914. 



The stone is a rather coarse, light brown sandstone 

 ■with abundant cla3'e3' cement. Under the microscope this 

 stone is seen to be ver}- uneven and while the average grain 

 is .5mm., some of the quartz particles reach a diameter of 

 1,25mm. (see microphotograph 16, plate X). The cement- 

 ing material is felspathic and rather abundant, ^^•hile 

 containing much more than the Yan Gan sandstone it has 

 less than the sandstone from Helidon. Two tests for 

 a,bsorption gave an average of 6.7% showing that it is rather 

 a porous stone. The beds are from 2 feet to 4 feet thick 

 and are fairJj- regularlj- jointed. The overburden is small 

 and the stone shows pretty concentric iron-staining. 



Beaudesert, Logan Village, Etc. 



A sandstone of rather poor qualities has been referred 

 to by E. 0. Marks* as occurring on Jenyu's selection, 

 about 4 miles west of Beaudesert. It has been used for 

 monumental jourposes and also for grindstones but in the 

 latter capacity it pro^"ed a failure. 



At Logan Village one or two quarries have been ojjened 

 in the sandstone which forms part of a belt of the Bundamba 

 sandstone running from Wolston to the foot of Tamborine 

 Mt. Watt's quarry, four miles from Logan Village, has a 

 rather coarse-grained stone apparently of poor quality. 

 Caradini"s quarry on the bank of the Logan River and one 

 uiile from the station yields a more inferior stone still. 



At Mundoolun, about 10 miles south of Logan Village, 

 a church has been erected of stone from the locality hy the 

 Collins family. It is a coarse-grained, broAvn sandstone 

 and from the belt of Bundamba sandstone mentioned above.
