The Distribution of Ammonium in Granites from South-West England
Journal of the Geological Society, London, Vol. 145, 1988, pp. 37-41, 1 fig., 5 tables. Printed in Northern Ireland The distribution of ammonium in granites from South-West England A. HALL Department of Geology, Royal Holloway and Bedford New College, Egham, Surrey TW20 OEX, UK Abstract: The ammonium contents of granites, pegmatites and hydrothermally altered rocks from SW England have been measured. Ammonium levels in the granites are generally high compared with those from other regions, averaging 36ppm,and they differ markedlybetween intrusions. The pegmatites show higherammonium contents than any other igneous rocks which have yet been investigated. Ammonium contents are strongly enriched in the hydrothermally altered rocks, includ- ing greisens and kaolinized granites. There is agood correlation between the average ammonium content of the intrusions in SW England and their initial "Sr/*'Sr ratios and peraluminosity. This relationship supports the hypothesis that the ammonium in the granites is derived from a sedimentary source, either in the magmatic source region or via contamination of the magma. Introduction Results Ammonium is present as a trace constituent of granitic The granites rocks, in which it occurs in feldspars and micas substituting isomorphously for potassium (Honma & Itihara 1981). The The new analyses of Cornubian granites are given in Table amount of ammonium in granites varies from zero to over 1. They show a range of 3-179 parts per million NH:, with 100 parts per million, and it has been suggested that high the highest values being found in relatively small intrusions. concentrations may indicate the incorporation of organic- Taking the averagefor each of the major intrusions,and rich sedimentary material into the magma, either from the weighting them according to their relative areas (see Table presence of such material in rhe magmatic source region or 4), the average ammonium contentof the Cornubian granites via the assimilation of organic-rich country rocks (Urano as a whole is 36 ppm. -

King Edward Mine Troon, TR14 9DP King Edward Mine, Troon, TR14 9DP Heritage Workshops for growing businesses Imagine working in an affordable rural environment that inspires creativity, forward thinking and business growth. Imagine having newly created office space in Grade II* Listed historic buildings sympathetically conserved and refurbished to the highest standards possible. Nine new workspace units at King Edward Mine, near Troon, West Cornwall have been created towards the rear of the site in the former Count House and Carpenters’ Shop. The units are of varying sizes with tenants already occupying some of the units. King Edward Mine, the former home of Camborne School of Mines, was acquired by Cornwall Council in 2009 and is substantially leased to a local charity to run as a mining heritage attraction. The site is recognised as having Outstanding Universal Value as the oldest, best preserved mine within the Cornish Mining World Heritage Site (WHS) for the pre-1920 period. The entire complex is within the WHS and includes sixteen Grade II* Listed buildings, the Grade II Listed South Condurrow Stamps Engine House and benefits from the Great Flat Lode mineral tramway multi-use trail passing through the site. The development has been made possible thanks to a grant of over a million pounds from the ERDF Convergence Programme and funding from Cornwall Council. Using local expertise and traditional building techniques, both buildings have been comprehensively restored to offer a range of accommodation Terms of Letting and facilities. All units are offered on new leases for a minimum term of 3 years.

The site and museum offer an incredible insight into the region’s industrial heritage and contains 16 Grade II* listed buildings. The derelict former Assay Office was restored and LEADER funding has enabled a community café to open in this historic building which Tamsin Daniel, Culture Programme has attracted new visitors to the site and Officer from Cornwall Council, said: the area. “Setting up a new café from scratch was always going to be a challenge. But we Economy and Sustainability consulted with the local community who were hugely supportive.” The LEADER funding enabled Cornwall Council to create an Kitchenside Bakery have an extensive attractive proposition for prospective following on social media and are franchisees. Following a shortlisting and experienced at running campaigns to interviewing phase Kitchenside Bakery attract visitors.

Cornwall & Isles of Scilly Landscape Character Study
CORNWALL AND ISLES OF SCILLY LANDSCAPE CHARACTER STUDY Overview and Technical Report Final Report May 2007 Forward The Cornwall and Isles of Scilly Landscape Character Study 2005-2007 has been developed as a joint project between the local authorities in Cornwall, the National Trust and the AONB units of Cornwall, the Tamar Valley and the Isles of Scilly supported by the Countryside Agency (now Natural England). Diacono Associates in conjunction with White Consultants were appointed in 2005 to undertake a Landscape Character Assessment for Cornwall and the Isles of Scilly. This updates the Cornwall Landscape Assessment published in 1994. This report sets out the methodology by which Landscape Character Areas have been identified, based on Landscape Description Units, and brings together the main findings of the study including the initial consultation stages. Part of the study included an assessment of landscape sensitivity at the level of the Landscape Description Units. This aspect of the study is however to be the subject of further investigation and the findings set out in this report have not therefore been endorsed at this stage by the participating organisations. This report will form the basis of a number of areas of further research and investigation including landscape sensitivity, and seascape assessment as well as the further consultation on the draft Landscape Character Area Descriptions.

All rights reserved. Cornwall County Council 100019590, 2008. Location Upland plateau located south of Redruth/Camborne. Designations AONB on the very southern fringes [LDUs 163, 164]; 3 separate WHS in LDUs 163, 168, 258; LDU 258 has SSSI; 2 LDU have SMs and 3 LDUs have CGS. Description The area is an elevated undulating granite plateau with outcrops in places and incised by stream valleys towards the edge. It is boggy in places and the soils are impoverished and humic. The area is open and exposed with few trees on the tops although there are some limited broadleaved plantations in the valley heads and bottoms. The field pattern varies from small fields within a medieval landscape of Anciently Enclosed Land around the fringes of the upland, bounded by sinuous Cornish hedges or hedgerows, to more recent enclosure of former rough ground into strongly rectilinear field patterns. Some areas of rough ground survive. The land is mainly down to permanent pasture with some rough grazing. The heath and wetland habitats are small and fragmented but most link along the stream valleys to form valuable ecological corridors. Some fields are being invaded by scrub. The settlement pattern is of dispersed farmsteads and small clusters of modest cottages, single or in terraces, in former industrial areas. There are also some larger industrial settlements such as Troon, Beacon and Pengegon, based primarily on terraces. Mining (tin and copper) and quarrying have been of major importance in the area in the past. -
