The sand and gravel resources of the country north and west of Billingham, Cleveland : description of 1:25,000 sheets NZ 42 and part of NZ 52

The geological maps of the Institute of Geological Sciences, pre-existing borehole information, and 70 boreholes drilled for the Industrial Minerals Assessment Unit form the basis of the assessment of the sand and gravel resources of the country north and west of Billingham, Cleveland. All the deposits in the district that might be potentially workable for sand and gravel have been investigated and a simple statistical method has been used to estimate the volume. The reliability of the volume estimates is given at the symmetrical 95 per cent probability level. The mineral-bearing ground is divided into two resource blocks, containing 12.5 and 10.6 km2 of potentially workable sand and gravel. For each block the geology of the deposits is described, and the mineral-bearing area, the mean thickness of overburden and mineral and the mean gradings are stated. Detailed borehole data are also given. The geology, the position of the boreholes and the outlines of the resource blocks are shown on the accompanying map

The sand and gravel resources of the country around Prees, Shropshire : description of 1:25,000 sheet SJ 53

The geological maps of the Institute of Geological Sciences, pre-existing borehole information, and 88 boreholes drilled for the Industrial Minerals Assessment Unit form the basis of the assessment of the sand and gravel resources of the country around Prees, Shropshire. All the deposits in the district that might be potentially workable for sand and gravel have been investigated and a simple statistical method has been used to estimate the volume. The reliability of the volume estimates is given at the symmetrical 95 per cent probability level. The 1:25 000 map is divided into six resource blocks, containing between 9.1 and1 6.5 km2o f potentially workable sand and gravel. For each block the geology of the deposits is described, and the mineral-bearing area, the mean thickness of overburden and mineral and the mean gradings are stated. Detailed borehole data are also given. The geology, the position of the boreholes and the outlines of the resource blocks are shown on the accompanying map. As a result of this survey, the line of the Wem fault shown on the published one-inch map (sheet 138) has been realigned up to 0.7km north-westwards, and a previously unknown subcrop, beneath drift, of Northwich Halite (Lower Keuper Saliferous Beds) probably exists south-east of this fault. Extensive deposits of laminated clay, with rhythmite sequences in part, occur beneath the outwash plain of Prees Heath

The sand and gravel resources of the country north-west of Scunthorpe, Humberside : description of 1:25,000 resource sheet SE 81

The geological maps of the Institute of Geological Sciences, pre-existing borehole information, and 63 boreholes drilled for the Mineral Assessment Unit form the basis of the assessment of sand and gravel resources of the country north-west of Scunthorpe, Humberside. All the floodplain deposits in the area which might be potentially workable for sand and gravel have been investigated and a simple statistical method has been used to estimate the volume. The reliability of the volume estimates is given at the symmetrical 95 per cent probability level. The 1:25000 map is divided into six resource blocks containing between 7.1 and 13.5 km2 of potentially workable sand and gravel. For the blocks assessed statistically the geology of the deposits is described and the mineral-bearing area, the mean thickness of overburden and mineral, and the mean grading of the mineral are stated. Detailed borehole data are given. The geology, the position of the boreholes and the outlines of the resource blocks are shown on the accompanying map

The MALSF synthesis study in the central and eastern English Channel

The need for effective stewardship of the marine environment through integrated management, balancing the requirements for development and exploitation with nature conservation and legislation, has been widely recognised. However, implementing such a strategy requires a significant knowledge of the nature of the sea bed. Acquiring such knowledge in the central and eastern English Channel (Figure 1) has been a focus of the Marine Aggregate Levy Sustainability Fund (MALSF) since 2005. The MALSF has funded a series of surveys to acquire high resolution data and its subsequent interpretation, along with other data, using a multi-disciplinary approach including geologists, biologists and archaeologists. This has produced a great deal of beneficial cooperation and interaction between these disciplines and enhanced the quality of the interpretations and results

Outer Bristol Channel marine habitat study : 2003 investigations and results

This report describes the investigations undertaken by the British Geological Survey (BGS) and the National Museums and Galleries of Wales (NMGW) during 2003 for the Outer Bristol Channel Marine Habitat Study, and the results and interpretations completed by March 2004 for the elements of the study funded by the Sustainable Land Won and Marine Dredged Aggregate Minerals Programme of the Office of the Deputy Prime Minister. The complete study is a three year programme which is planned to end in March 2006. The other principal funder of the study is the Aggregate Levy Sustainability Fund for Wales, which is administered by the Welsh Assembly Government. The Crown Estate and the British Marine Aggregate Producers Association have also supported the study with some funding and contributions of data. Pressure on marine resources in the Bristol Channel continues to develop with a number of issues including aggregates, fisheries and wind farm developments. There are also legislative obligations with regard to marine conservation, in a European context with the Habitats Directive and in national initiatives such as the designation of Carmarthen Bay, the Pembrokesire Coast and Lundy as candidate Special Areas of Conservation (cSACs). To inform the policy and decision making process in terms of developments in the marine environment requires knowledge of its current physical state. This includes the morphology, geology, biology and sediments of the seabed. Baseline information on these is essential for strategic management and the conservation of biological diversity. Responsible stewardship requires an understanding of the way the marine environment functions and how the sea may respond to human activity. It also means involving stakeholders as an integral part of policy making. The Bristol Channel Marine Aggregates: Resources and Constraints Research Project (Posford Duvivier & ABP Research, 2000), indicated significant gaps in the biological and geological data available for the Outer Bristol Channel area. The only comprehensive study of the benthic invertebrates (Warwick & Clark 1977) was carried out in 1972-1973 and British Geological Survey maps of the area were based on surveys undertaken from 1971 to 1976
