This bending, breaking and buckling of crust produces folds and faults in rocks. Intrusions of granitic rocks form by heat 'cells' deep in the crust that cause rocks to melt; they also start chemical reactions in surface rocks pushed down in the crust where they are changed to metamorphic rocks.

Several faults (such as the Guodishan fault) and folds (such as the Niuzhuang syncline and Guozhuang anticline) are widely distributed in the mining district (Figs. 2 and 9b), and the in situ ...

Neotectonics contains information on faults, folds and other features within Australia that are demonstrated or suspected to relate to the occurrence of large earthquakes during the period that the current crustal stress field has pertained (i.e., the past 5–10 million years).

Dominantly NW-SE striking faults spatially associated with the Mt. Arrowsmith Volcanics. Faults that are spatially related to the Neoproterozic (c. 585 Ma) mafic igneous Mount Arrowsmith Volcanics. These igneous rocks and associated faults may host magmatic nickel-sulfide and remobilised copper (Gilmore et al., 2007).

The Geological Survey of NSW has released a 3D model of major faults in the eastern Lachlan Orogen using all available geological mapping, borehole and geophysical data. The model is a powerful tool for studying the evolution of geology in NSW over the past 500 million years and gives a geological context for the location of major mineral ...

What is the NSW Seamless Geology? An initial five-year project (2013–2018) to complete Version 1 of the statewide product. Joins the best-available geological mapping (on a variety of scales) across NSW. Connects line mismatches (e.g. geological boundaries, faults etc.) across existing geological map sheet boundaries.

Tasmania in 1883-1892, the large events of the swarm felt in southeastern NSW. The largest known NSW earthquakes were those at Gunning in 1934 and Newcastle in 1989, magnitude 5.6, but several others were almost as large.

2013年7月20日 · The Demon Fault is mainly a transverse type fault (movement on the fault horizontally rather than vertically) which displays very obvious topographical features. Transverse faults often form valleys, where the rock of the fault has been broken down into what is called gouge or rock-flour. Gouge is very weak material.

Many mapped faults in the south-eastern highlands of New South Wales and Victoria are associated with apparently youthful topographic ranges, suggesting that active faulting may have played a role in shaping the modern landscape. This has been demonstrated to be the case for the Lake George Fault, ~25 km east of Canberra.

2008年9月26日 · “There are numerous young faultlines weaving their way across southern Australia, including one that goes right around the perimeter of Adelaide. There are also young faultlines running through the Mornington Peninsula outside Melbourne, the Strzelecki Ranges in Victoria and the Flinders Ranges in South Australia.
