Sydney Basin coalfields; Queensland ... Upper Silesian Coal Basin; Russia. Ulug-Khem coal basin; ... Coalfields and Producing Districts (Map). Scale 1:1,000,000.
The Oaklands Basin hosts to more than 1000 m thick sediments. The basin was first discovered in 1916 when water drillers discovered coal near Coorabin. Coal has been the main focus for exploration within the basin since this time. Extensive coal exploration drilling has been undertaken, mostly in the Coorabin area.
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).
Coal mining requires a pollution control ('environment protection') licence under the Protection of the Environment Operations Act 1997 (NSW) if it exceeds the following thresholds set out in Schedule 1 of the Act: if it is mining, processing or handling of coal (including tailings and chitter) at underground mines or open cut mines and (a) it ...
The coastal coal-carrying trade of New South Wales involved the shipping of coal—mainly for local consumption but also for export or coal bunkering—by sea to Sydney from the northern and southern coal fields of New South Wales. It took place in the 19th and 20th centuries.
Newcastle Coal Measures is a major geologic formation in eastern Australia. Found in the Sydney Basin and Lachlan Orogen, this stratum is up to 1200 metres thick, consisting of dozens of different sub types. Formed between the Changhsingian and Wuchiapingian ages, around 256 to 252 Ma in the Permian. This formation includes coal seams, tuffaceous claystone, siltstone, sandstone, and ...
Exposed Ashfield Shale of the Wianamatta group, by the Pacific Highway, Chatswood, Australia. The Wianamatta Group is a geological feature of the Sydney Basin, New South Wales, Australia that directly overlies the older (but still Triassic in age) Hawkesbury sandstone and generally comprise fine grained sedimentary rocks such as shales and laminites as well as less common sandstone units.
Ashfield Shale is part of the Wianamatta group of sedimentary rocks in the Sydney Basin. It lies directly on contemporaneously eroded Hawkesbury sandstone or the Mittagong formation. These rock types were formed in the Triassic Period. [1] It is named after the Sydney suburb of Ashfield. Some of the early research was performed at the old ...
