History Of The Isle Of Wight
The Isle of Wight is rich in historical and archaeological sites, from prehistoric fossil beds with dinosaur remains, to dwellings and artefacts dating back to the Bronze Age, Iron Age, and Roman periods. Formation The River Solent was the largest tributary of the Channel River that drained the Hampshire Basin from the Early Pleistocene or late Pliocene. During the Mesolithic period, sea levels in northern Europe were some 30 to 40 metres lower than today, and the land that became Britain was a peninsula of northern Europe. The island was formed at the end of the last Ice Age, about 8–9000 years ago, as sea levels rose, and the land of southern Britain sunk due to the post-glacial rebound of the north that had been under the ice. This flooded the former river valley of the Solent to the north, and the future English Channel to the south, and cut Wight off from the island of Britain. Once open to the sea, tidal scouring widened the Solent. Early history Prehistory The first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleolithic
The Paleolithic or Palaeolithic ( years ago) ( ), also called the Old Stone Age (), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost the entire period of human prehistoric technology. It extends from the earliest known use of stone tools by Hominini, hominins, 3.3 million years ago, to the end of the Pleistocene, 11,650 Before Present#Radiocarbon calibration, cal Before Present, BP. The Paleolithic Age in Europe preceded the Mesolithic Age, although the date of the transition varies geographically by several thousand years. During the Paleolithic Age, hominins grouped together in small societies such as band society, bands and subsisted by gathering plants, fishing, and hunting or scavenging wild animals. The Paleolithic Age is characterized by the use of Knapping, knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for ...

Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon). These additions produce a range of alloys some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability. The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Smelting
Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. It is a form of extractive metallurgy that is used to obtain many metals such as iron-making, iron, copper extraction, copper, silver mining#Ore processing, silver, tin, lead smelting, lead and zinc smelting, zinc. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal behind. The reducing agent is commonly a fossil-fuel source of carbon, such as carbon monoxide from incomplete combustion of coke (fuel), coke—or, in earlier times, of charcoal. The oxygen in the ore binds to carbon at high temperatures, as the Chemical energy, chemical potential energy of the bonds in carbon dioxide () is lower than that of the bonds in the ore. Sulfide ores such as those commonly used to obtain copper, zinc or lead, are roasting (metallurgy), roasted before smelting in order to convert the sulfid ...

Mining In Cornwall And Devon
Mining in Cornwall and Devon, in the southwest of Britain, is thought to have begun in the early-middle Bronze Age with the exploitation of cassiterite. Tin, and later copper, were the most commonly extracted metals. Some tin mining continued long after the mining of other metals had become unprofitable, but ended in the late 20th century. In 2021, it was announced that a new mine was extracting battery-grade lithium carbonate, more than 20 years after the closure of the last South Crofty tin mine in Cornwall in 1998. Historically, tin and copper as well as a few other metals (e.g. arsenic, silver, and zinc) have been mined in Cornwall and Devon. Tin deposits still exist in Cornwall, and there has been talk of reopening the South Crofty tin mine. In addition, work has begun on re-opening the Hemerdon tungsten and tin mine in southwest Devon. In view of the economic importance of mines and quarries, geological studies have been conducted; about forty distinct minerals have ...

Bronze Age Britain
Bronze Age Britain is an era of British history that spanned from until . Lasting for approximately 1,700 years, it was preceded by the era of Neolithic Britain and was in turn followed by the period of Iron Age Britain. Being categorised as the Bronze Age, it was marked by the use of copper and then bronze by the prehistoric Britons, who used such metals to fashion tools. Great Britain in the Bronze Age also saw the widespread adoption of agriculture. During the British Bronze Age, large megalithic monuments similar to those from the Late Neolithic continued to be constructed or modified, including such sites as Avebury, Stonehenge, Silbury Hill and Must Farm. That has been described as a time "when elaborate ceremonial practices emerged among some communities of subsistence agriculturalists of western Europe". History Early Bronze Age (EBA), c. 2500–1500 BC There is no clear consensus on the date for the beginning of the Bronze Age in Great Britain and Ireland. Some ...

Ingot
An ingot is a piece of relatively pure material, usually metal, that is Casting, cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots usually require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may also be referred to as ingots, particularly when cast by mold based methods. Precious metal ingots can be used as currency (with or without being processed into other shapes), or as a currency reserve, as with gold bars. Types Ingots are generally made of metal, either pure or alloy, heated past its melting point and cast into a bar or block using a mold chill method. A special case are polycrystalline or single crystal ingots made by pulling from a molten melt. Single crystal Single crystal ingots (called boule (crystal), boules) of materials are grown (crystal growth) using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Iron Age
The Iron Age () is the final epoch of the three historical Metal Ages, after the Chalcolithic and Bronze Age. It has also been considered as the final age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic, Mesolithic and Neolithic) and Bronze Age. These concepts originated for describing Iron Age Europe and the ancient Near East. In the archaeology of the Americas, a five-period system is conventionally used instead; indigenous cultures there did not develop an iron economy in the pre-Columbian era, though some did work copper and bronze. Indigenous metalworking arrived in Australia with European contact. Although meteoric iron has been used for millennia in many regions, the beginning of the Iron Age is defined locally around the world by archaeological convention when the production of smelted iron (especially ...

Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The list of Middle Eastern countries by population, most populous countries in the region are Egypt, Turkey, and Iran, whil ...

Bouldnor Cliff
Bouldnor Cliff is a submerged prehistoric settlement site in the Solent. The site dates from the Mesolithic era and is in approximately of water just offshore of the village of Bouldnor on the Isle of Wight in the United Kingdom. The preservation of organic materials from this era that do not normally survive on dry land has made Bouldnor important to the understanding of Mesolithic Britain, and the BBC Radio 4's ''Making History'' programme described it "probably Europe's most important Mesolithic site" albeit concealed under water. The site was first discovered by divers from the Hampshire and Wight Trust for Maritime Archaeology (now the Maritime Archaeology Trust) in 1999, when a lobster was observed discarding worked flint tools from its burrow on the seabed. Since then, several years of fieldwork have revealed that Bouldnor was a settlement site about 8,000 years ago, at a time when lower sea levels meant that the Solent was just a river valley. The work done so f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Era (geology)
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardised international units of geological time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely de ...
