LIMESTONE CAVES OF NSW

  ROSEBROOK CAVES                             The Rosebrook Caves have been formed in an extensive belt of limestone (the Bunyan Limestone) a few km north-west of Cooma in southern NSW. The caves described below are located in the northern part of the outcrop. Some of karst features in the limestone appear to be quite ancient. Fossils are relatively rare. The first mention of Rosebrook Caves that I have found was in the DailyTelegraph (Sydney) Tuesday 26th January 1892. " CAVES DISCOVERED NEAR COOMA , Monday.  Last week a few persons descended a hole on Rosebrook Station, six miles from Cooma, From Carne & Jones. The cave is under the M of "Woolumla" which has been known for years,in the hope of finding a cave. After descending about 60ft. they came to a chamber 30ft. high by 20ft. wide by 40ft. long. The cave was surrounded by splendid formations of stalagmites and stalactites, many of which were accid...

ABERCROMBIE CAVES Image from NPWS The Abercrombie Caves are located about  70  km south of Bathurst. They lie on  Grove Creek,  a tributary  of the Abercrombie River.    The dominant feature is the archway through which Grove Creek passes. The Limestone Deposits of NSW (Lishmund et al) has this to say about the  geology of the area.   "The Abercrombie Caves limestone deposit is part of the Kildrummie Formation which here consists of quartz-rich slate and chert, thick limestone units, and thin horizons of  basic volcanics. The limestone is thickest near the arch at Abercrombie Caves where it is about 300 m thick. North and  south of the caves it decreases quite rapidly. "  F ossils within these strata date from the late Silurian period. As with most of the Lachlan fold belt, the folded strata and volcanics crop out in zones which run generally north-south. History of the area . The local indigenous people no doubt used the arc...
