Dark Earth

	Dark Earth In geology and archaeology, dark earth is a substratum, up to thick, that indicates settlement over long periods of time. The material is high in organic matter, including charcoal, which gives it its characteristic dark colour; it may also contain fragments of pottery, tile, animal bone and other artefacts. It is interpreted as soil enriched with the sooty remains of thatched roofs from houses without chimneys, with other waste materials. In some areas it appears to give the soil added fertility. London's dark earth was originally called 'black earth' by archaeologists. It was renamed 'dark earth' because of confusion with the ''chernozem'' (black earth soils in Russia), whose dark colour is traditionally (not universally) thought to come from humus, rather than soot. Charred material as agricultural improver In the Hebrides, it was customary to remove the thatch from the "black houses" every spring, and spread it on the fields as fertilizer, improved by the soot which it re ...

picture info	Geology Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Uppåkra Uppåkra is a village and parish in Staffanstorp Municipality, in Scania, southern Sweden, located five kilometres south of Lund. The village is known for its Iron Age archaeological site, which has been actively excavated since 1996. History Uppåkra was situated on the ancient main road between Trelleborg and Helsingborg in what was to become the Denmark, Danish kingdom. The original foundation of Uppåkra is dated to the last century BC, although its importance appears to have increased in the fifth century. It seems likely that the rulers of Uppåkra by then wielded influence over most or all of West Scania, i.e. the land along the Trelleborg–Helsingborg main road, known for extraordinarily fertile plains. Uppåkra declined and was possibly in part relocated to Lund in the 990s. Knowledge about the decline of Uppåkra and the relocation to Lund is still unsure. Hence Uppåkra is held to be the direct predecessor of the city of Lund. However, the area has been continuous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
