Grose Valley
The Grose Valley is a rugged valley in the Blue Mountains, New South Wales, Australia. It has been formed by the Grose River, the headwaters of which are in the Mount Victoria area. The valley is located between the Great Western Highway and Bells Line of Road, the two major routes across the Blue Mountains. The majority of the valley falls within the Blue Mountains National Park. Grose wilderness features The Grose Wilderness contains some of the most dramatic gorge and canyon landscapes of the entire Sydney basin sandstone region. The Grose also constitutes one of the most accessible wilderness areas for bushwalking or public observation from its escarpment margins. Geology The geology of the area consists of Triassic sandstones and underlying Permian sedimentary rocks. A number of basalt-capped peaks dominate the area, notably Mount Banks and Mount Hay. The Grose River and its tributaries have eroded an extensive labyrinth of gorges and canyons through the Hawkesbury ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sydney Basin
The Sydney Basin is an interim Australian bioregion and is both a structural entity and a depositional area, now preserved on the east coast of New South Wales, Australia and with some of its eastern side now subsided beneath the Tasman Sea. The basin is named for the city of Sydney, on which it is centred. Around thick, the Sydney Basin consists of Permian and Triassic sedimentary rocks, which stretches from Newcastle in the north to Batemans Bay in the south, and west to the Great Dividing Range. The basin is also home to the major centres of Newcastle and Wollongong, New South Wales, Wollongong, and contains economically significant reserves of coal. Sydney's famous Port Jackson, harbour and the sculptured cliffs of the Blue Mountains (New South Wales), Blue Mountains are signature formations of relatively hard upper strata of sandstone. The basin contains the UNESCO World Heritage Site, UNESCO World Heritage-listed Greater Blue Mountains Area. Geography According to De ...

Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sassafras
''Sassafras'' is a genus of three extant and one extinct species of deciduous trees in the family Lauraceae, native to eastern North America and eastern Asia.Wolfe, Jack A. & Wehr, Wesley C. 1987. The sassafras is an ornamental tree. "Middle Eocene Dicotyledonous Plants from Republic, Northeastern Washington". ''United States Geological Survey Bulletin'' 1597:13 The genus is distinguished by its aromatic properties, which have made the tree useful to humans. Description Sassafras trees grow from tall with many slender sympodial branches and smooth, orange-brown bark or yellow bark. All parts of the plants are fragrant. The species are unusual in having three distinct leaf patterns on the same plant: unlobed oval, bilobed (mitten-shaped), and trilobed (three-pronged); the leaves are hardly ever five-lobed.Noble Plant Image GallerSassafras (includes photo of five-lobed leaf) Three-lobed leaves are more common in ''Sassafras tzumu'' and '' S. randaiense'' than in their North ...

Coachwood
''Ceratopetalum apetalum'', the coachwood, scented satinwood or tarwood, is a medium-sized hardwood tree, straight-growing with smooth, fragrant, greyish bark. It is native to eastern Australia in the central and northern coastal rainforests of New South Wales and southern Queensland, where is often found on poorer quality soils in gullies and creeks and often occurs in almost pure stands. ''C. apetalum'' is one of 8 species of ''Ceratopetalum'' occurring in eastern Australia, New Guinea, New Britain and various islands in the same region. Description Coachwood usually grows to a height of 25 metres, with a trunk diameter of , however exceptional specimens can reach 40 metres tall and live for centuries. The stem has distinctive horizontal marks, or scars, which often encircle the trunk. Larger trees have short buttresses. The heartwood is attractive with a colour ranging from pale pink to pinkish-brown. The sapwood is not always distinguishable, the grain is straight, finely ...

Angophora Costata
''Angophora costata'', commonly known as Sydney red gum, rusty gum or smooth-barked apple, is a species of tree that is endemic to eastern Australia. Reaching in height, the species has distinctive smooth bark that is pinkish or orange-brown when new and fades to grey with age. Its lance-shaped leaves are arranged in opposite pairs along the stems, with white or creamy white flowers appearing from October to December. The flower buds are usually arranged in groups of three, followed by ribbed, oval or bell-shaped fruit. Description ''Angophora costata'' is a tree that typically grows to a height of and forms a lignotuber. It has smooth pinkish or orange-brown bark that weathers to grey and is shed in small scales.

Eucalyptus Piperita
''Eucalyptus piperita'', commonly known as Sydney peppermint and urn-fruited peppermint, is a small to medium forest tree native to New South Wales, Australia.

Bright yellow-green flowers are borne in clusters of seven or more in late spring to mid summer. Fruit is urceolate (urn shaped) to barrel shaped, especially on the sides of valleys. Taxonomy and naming Specimens of ''E. piperita'' were first collected by First Fleet surgeon and naturalist John White, and published by James Edward Smith in his appendix to White's 1790 '' Journal of a Voyage to New South Wales''. Smith gave it the specific epithet ''piperita'' because its odour of its essential oil was so similar to that of ''Mentha'' × ''piperita'', the peppermint. White's ''Voyage'' also featured a plate showing the plant's leaves and old fruit, but no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Narrabeen Shale
The Narrabeen group of sedimentary rocks occurs in the Sydney Basin in eastern Australia. This series of rocks was formed in the Triassic Period. Geology It includes various rock types including lithic sandstone, quartz sandstone, siltstones, claystones, conglomerate and shales, some of which have fossils of plants and fish. Partly in these rocks plants, fish and amphibious animals are petrified. The red and green shales of the Narrabeen Group are water-tight over the sandstone bodies and the shale of Bald Hill, which forms the top layer of the Narrabeen Group, forms a regional water-barrier layer. Over the Narrabeen Group, the younger stratigraphic formation of Hawkesbury sandstones accumulated. Structure Above the Narrabeen group is the younger less fertile Hawkesbury sandstone. Below are Permian sedimentary rocks including measures of coal broadly known as the Illawarra Coal Measures. Whereabouts The Narrabeen group is most famously seen as The Three Sisters in t ...
