The tramline survived until due to a downturn in production during World War II the rails were lifted in 1943 and the bridge dismantled the following year. Remnants of the bridge supports are still visible on ...
Opal is a hydrated amorphous form of silica (SiO 2 ·nH 2 O); its water content may range from 3% to 21% by weight, but is usually between 6% and 10%. Due to the amorphous (chemical) physical structure, it is classified as a mineraloid, unlike crystalline forms of silica, which are considered minerals.
The majority of Sydney Basin is raised sandstone plateau, with the exception being the Hunter Valley and the low-lying Cumberland Plain.. Minor igneous activity took place in the basin during the Early Jurassic (i.e. 210 million years ago), Late Mesozoic (i.e. 100-90 million years ago) and Cenozoic eras (i.e. 65 million years ago).
