Dolphin Island (Western Australia)
Dolphin Island is an island situated in the Dampier Archipelago in the Pilbara region of Western Australia. Visitors are able to camp within of the high water mark on all of the beaches on the island except for the south eastern side. The island is designated as a B Class Nature Reserve (34944) and has a total area of . It is the second largest island of the archipelago after Enderby Island but it is the highest in the archipelago rising to above sea level. The island is composed of precambrian volcanic and granitic rocks with some outcrops of archaen granite and granite gneiss which are over 2400 Ma in age. The island is separated from the Burrup Peninsula by a major valley system formed by a regional fracture.

Dampier Archipelago
The Dampier Archipelago is a group of 42 islands near the town of Dampier in the Pilbara, Western Australia. The archipelago is also made up of reefs, shoals, channels and straits and is the traditional home of five Aboriginal language groups. It was formed 7000 years ago when rising sea levels flooded what were once coastal plains. The underlying rocks are among the oldest on earth, formed in the Archaean period more than 2400 million years ago. It is named after William Dampier, an English buccaneer and explorer who visited in 1699. Dampier named one of the islands Rosemary Island. Despite being a region through which considerable shipping and industrial activity occurs, the archipelago has considerable marine resources. History Dampier Archipelago is the site of some of Australia's oldest domestic structures, estimated to be between 8000 and 9000 years old. The largest island (or peninsula) in the group was known as ''Murujuga'' by the Yaburara people. The first Britis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilbara
The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). General The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of . It contains some of Earth's oldest rock formations, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.

Archaen
The Archean Eon ( , also spelled Archaean or Archæan) is the second of four geologic eons of Earth's history, representing the time from . The Archean was preceded by the Hadean Eon and followed by the Proterozoic. The Earth during the Archean was mostly a water world: there was continental crust, but much of it was under an ocean deeper than today's ocean. Except for some trace minerals, today's oldest continental crust dates back to the Archean. Much of the geological detail of the Archean has been destroyed by subsequent activity. The earliest known life started in the Archean. Life was simple throughout the Archean, mostly represented by shallow-water microbial mats called stromatolites, and the atmosphere lacked free oxygen. Etymology and changes in classification The word ''Archean'' comes from the Greek word (), meaning 'beginning, origin'. It was first used in 1872, when it meant 'of the earliest geological age'. Before the Hadean Eon was recognized, the Archean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding (gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fracture ...

Burrup Peninsula
Murujuga, formerly known as Dampier Island and today usually known as the Burrup Peninsula, is in the Dampier Archipelago, in the Pilbara region of Western Australia, containing the town of Dampier. The Dampier Rock Art Precinct, which covers the entire archipelago, is the subject of ongoing political debate due to historical and proposed industrial development. The Murujuga National Park lies within Burrup, and contains within it the world's largest collection of ancient rock art. The region is sometimes confused with the Dampier Peninsula, to the north-east. History The traditional owners, the Indigenous people of the Burrup Peninsula, are an Aboriginal nation known as the Yaburara (Jaburara) people. In Ngayarda languages, including that of the Aboriginal people of the peninsula, the Jaburara (or Yaburara) people, ''murujuga'' meant "hip bone sticking out". Between February and May 1869 a great number of Yaburara people were killed in an incident known as the Flying Foam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indigenous Australians
Indigenous Australians or Australian First Nations are people with familial heritage from, and membership in, the ethnic groups that lived in Australia before British colonisation. They consist of two distinct groups: the Aboriginal peoples of the Australian mainland and Tasmania, and the Torres Strait Islander peoples from the seas between Queensland and Papua New Guinea. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the terms First Nations of Australia, First Peoples of Australia and First Australians are also increasingly common; 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these indigenous Australians, 91.4% identified as Aboriginal; 4.2% identified as Torres Strait Islander; while 4.4% identified with both groups.

Yapurarra
The Yapurarra or Jaburara, also rendered Yaburara, are an Aboriginal Australian people whose traditional lands are in the Pilbara region of Western Australia and the Dampier Archipelago. Language The Jaburara language (Yaburarra) is thought to have been similar to Ngarluma, part of the Ngayarda languages. Country The Jaburara owned some of territory from around Dampier, Burrup, Nichol Bay and the peninsula northwards to the Dolphin and Legendre islands. Early contact During one of Phillip Parker King's voyages on to survey the Australian coast, an attempt was made to communicate in February 1817 with members of the tribe, three of whom had been sighted off-shore floating on a log in the vicinity of present-day Karratha. The intermediary used was the ship's interpreter Bungaree, who, speaking the Broken Bay Dharug language could not understand them, but managed to calm their anxieties by undressing and showing he wore ritual scars. Resistance and extinction The Jaburara, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traditional Owners
Native title is the designation given to the common law doctrine of Aboriginal title in Australia, which is the recognition by Australian law that Indigenous Australians (both Aboriginal Australian and Torres Strait Islander people) have rights and interests to their land that derive from their traditional laws and customs. The concept recognises that in certain cases there was and is a continued beneficial legal interest in land held by Indigenous peoples which survived the acquisition of radical title to the land by the Crown at the time of sovereignty. Native title can co-exist with non-Aboriginal proprietary rights and in some cases different Aboriginal groups can exercise their native title over the same land. The foundational case for native title in Australia was ''Mabo v Queensland (No 2)'' (1992). One year after the recognition of the legal concept of native title in ''Mabo'', the Keating Government formalised the recognition by legislation with the enactment by the Au ...

Francis Thomas Gregory
Francis Thomas "Frank" Gregory (19 October 1821 – 23 October 1888) was an Australian explorer and politician. Born in England, he emigrated with his family to Australia as a boy. He was the younger brother of the explorer and politician Augustus Gregory, who also made his career in the colony. Biography Gregory was born at Farnsfield, Nottinghamshire, England in 1821. His family, including his older brother Augustus, emigrated to Western Australia in 1829. After getting a basic education, Gregory entered the Western Australian public service in 1841 as a cadet surveyor. In 1846, Gregory accompanied his older brother Augustus and explorer Henry Churchman, to investigate the country north of Perth. The following year, Gregory was appointed an assistant government surveyor; two years later he was promoted to staff surveyor in 1849. In 1857 he led expeditions to the upper Murchison River, and to country farther east and north in 1858. The next year Gregory visited England, t ...
