You are as well aware as I am of the extreme difficulty of following out any particular bed in the Australian coal measures in consequence of the great variableness of their condition, a remark which applies so generally to all members of the carboniferous (now dated as Permian) formation in N.S.W., that it is not safe to trust any of the rocks further than you can throw them (see Moyal 2003).
However, the Lower Paleozoic natural gas was generally believed to be mixed by both coal-type gas from the Upper Paleozoic coal measures and oil-type gas from the marine source rocks [27-29].
The exhibition is called Farewell Rock, which is also the name for the band of sandstone that lies below the coal measures. When miners reach it, it signals 'a farewell to riches' and the end of coal and is an apt reflection on the region's mothballed cast mines and the colliery's uncertain future.
