Maritime Museum of Tasmania
The island state of Tasmania has a long and rich history of association with the sea, going back well before the time of British invasion and settlement on the island. The indigenous Tasmanians were known to have strong affiliations with the sea, and surrounding islands.
The British of course arrived by sea, and since the time of their first arrival in 1803, Tasmania has had a continuous history or sailing, maritime trade, fishing and other maritime activities. The museum sets out to chart, document and display materials and artefacts related to that history.
Maritime enthusiasts first began to argue that the Tasmanian Museum and Art Gallery should include a room dedicated to Tasmania's maritime history in the 1930s. However it wasn't until 1972, when six volunteers decided to create a dedicated museum, that the Maritime Museum of Tasmania was born. It was originally housed in St. George's Church, Battery Point, and opened in 1973, with an official opening in 1974.
Geology of Tasmania
The earliest geological history is recorded in rocks from over . Older rocks from western Tasmania and King Island were strongly folded and metamorphosed into rocks such as quartzite. After this there are many signs of glaciation from the Cryogenian, as well as the global warming that occurred at the start of the Ediacaran period. An orogeny folded the older Precambrian rocks. In the Cambrian time the Tyennan block forming the south west and central Tasmania, was pushed up and slightly over the land of north west Tasmania, the Tyennan Orogeny. Then there were volcanic action and sediments from the Cambrian and Ordovician. The large ore deposits were formed on the West Coast. The north east of Tasmania began to form as part of the Lachlan Orogen with turbidity flows of mud and sand on to the ocean floor. In the Devonian the Tabberabberan Orogeny caused more folding, and intrusion of granite on the west and east coasts, and probably joined the east of Tasmania to the west.
