	Geology - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-20)
		Geology (from Greek γη- (ge-, "the earth") and λογος (logos, "word", "reason")) is the science and study of the solid matter of a celestial body, its composition, structure, physical properties, history and the processes that shape it.
		The word "geology" was first used by Jean-André Deluc in the year 1778 and introduced as a fixed term by Horace-Bénédict de Saussure in the year 1779.
		In geology, when an igneous intrusion cuts across a formation of sedimentary rock, it can be determined that the igneous intrusion is younger than the sedimentary rock.

	GENERAL LANDSCAPE FEATURES OF HERTFORDSHIRE
		Many villas were built in Hertfordshire and the villa of Gorhambury, for example, shows evidence of the use of the landscape for recreational purposes, in that there was probably a covered walkway and an avenue of trees and shrubs.
		Hertfordshire shares much in common with other Home Counties in its pattern of development from the 17th century onwards, although the construction of the New River in the Lea Valley to supply London with water was notable.
		Hertfordshire became a commuter belt; free first-class railway tickets were handed out to purchasers of the houses in the new garden cities.

	Introduction To The Geology Of Hertfordshire
		Hertfordshire’s main topographic features, such as the Chiltern Hills and Vale of St. Albans, its valley patterns and soil types are all determined by the geological history of the area.
		This is because at the end of the Cretaceous Period the rocks were uplifted and tilted, and then eroded unevenly before the next sediments were laid down on the eroded surface in the Palaeocene Period about 65 million years ago.
		The main Palaeocene deposit in Hertfordshire is the Reading Beds, which consists of 30-50 ft of multicoloured clays with irregular patches of yellow sand and occasional bands of small (1-5 cm) fl pebbles.

	Geology of Hertfordshire - Wikipedia, the free encyclopedia
		The rocks of the English county of Hertfordshire belong to the great shallow syncline known as the London basin, the beds dip in a south-easterly direction towards the syncline's lowest point roughly under the River Thames.
		The most important formations are the Cretaceous chalks, which are exposed as the high ground in the north and west of the county, and the Tertiary rocks made up of the Paleocene age Reading Beds and Eocene age London Clay that occupies the remaining southern part.

		Geology (from Greek andgamma;andeta;- (ge-, "the earth") and andlambda;andomicron;andgamma;andomicron;andsigmaf; (logos, "word", "reason")) is the science and study of the Earth, its composition, structure, physical properties, history, and the processes that shape it.
		Geologists have helped establish the age of the Earth at about 4.5 billion (4.5x109) years, and have determined that the Earth's lithosphere, which includes the crust, is fragmented into tectonic plates that move over a rheic upper mantle (asthenosphere) via processes that are collectively referred to as plate tectonics.

		Geology.—The rocks of Hertfordshire belong to the shallow syncline known as the London basin, the beds dipping in a southeasterly direction.
		A particularly good account of Hertfordshire's topography is A Landscape Strategy for Hertfordshire, produced by the County Council in 1997 and published on-line in 2001.
		The road continued under the jurisdiction of the justices until 1733, when its Hertfordshire section, from Wadesmill to Royston, was taken over by a Wadesmill Turnpike Trust composed at first of local gentry, parsons and influential farmers.

		The bedrock geology of the region consists largely of Jurassic strata that outcrop in the west but are overlain in the east by shallow dipping Cretaceous sediments including the Chalk Group that extend eastwards across the region into north-east Norfolk.
		Truncating the underlying solid and superficial sequences are thick accumulations of glacigenic sediments laid down by ice sheets during several middle and late Pleistocene glaciations.
		The main objective of this programme is to complete and update to a baseline 1:50 000-scale geological map coverage of the bedrock geology and superficial deposits within the Eastern Geological Framework project region, and to construct shallow 3D geological models – LithoFrame 10 and 50 – where appropriate.

	Hertfordshire Biological Records Centre - Hertfordshire's wildlife (Site not responding. Last check: 2007-10-20)
		Hertfordshire's countryside has been shaped by the interactions of climate, vegetation, animals, geology and soil, and above all, by the activities of man. this process of change began 7,000 years ago when Neolithic farmers first began to clear the land to grow cereal crops.
		Plants and animals responded and adapted to these changes so that as woodland areas were cleared, areas of grassland and heathland arose with their characteristic plant and animal communities creating a rich mosaic of landscape features.
		Although there have been some gains in the creation of reservoirs and flooded gravel pits by amenity tree planting and small scale habitat creation schemes, these are far outweighed by the losses.

		During the Ice Age the Thames became blocked in Hertfordshire by a glacier and a large lake was formed.
		This lake eventually forced a new path which led to the Thames and Medway adopting its current route.

		In East Hertfordshire half round bricks often associated with canted (splayed) plinth bricks and purpose made curved or angled top coping bricks or tile creasing are much used and are an attractive 'hat' to such a wall.

		These are the first inquiries with which Geology is occupied, a science which derives its name from the Greek ge, the earth, and logos, a discourse.
		In some conglomerates, like the pudding-stone of Hertfordshire (a Lower Eocene deposit), pebbles of flint and grains of sand are united by a siliceous cement so firmly, that if a block be fractured, the rent passes as readily through the pebbles as through the cement.
		It moreover appeared clear, as the science of geology advanced, that certain spaces on the globe had been alternately sea, then land, then estuary, then sea again, and, lastly, once more habitable land, having remained in each of these states for considerable periods.

	Introduction (Site not responding. Last check: 2007-10-20)
		The surface geology of Hertfordshire defined the location of the original settlements when Britain was initially colonised.
		Evidence from pollen grains trapped in the silts and peats of the River Ver (the namesake of the Roman centre Verulanium, and a tributary of the Colne), has shown that the original forest was replaced very early by farmland in the whole valley.
		The inhabitants of Braughing took advantage of the rich pasture lands in East and Central Hertfordshire, raising animals such as sheep, goats, cattle, pigs and horses in the late Iron Age.

		It proved a lot dryer, so, quickly up went the tents, and even quicker we found ourselves sampling the delights of the pub in Capel Curig, where we could work out our routes for the next day in a warm and friendly atmosphere.
		But the weirdness of a group of geology students from Hertfordshire Uni, who, instead of Snowdonia “usually just go down to Switzerland or somewhere” to peer at rocks, was a little too much to escape our attention, especially the one dressed in full army-combats and Jamaican flag which doubled as a fetching bandanna.
		It offers untold scrambling opportunities over a jumble of elephant-sized boulders, arranged in such a way that even the most adept Hertfordshire geology student would be completely befuddled, and its sheer imposing stature is enough to awe the hardiest of Ben Lairigers.
