Geology of the Hatta 1:50 000 map sheet, 50-5, United Arab Emirates

Abstract

This report is a description of the 1:50 000 scale Hatta geological map sheet. It forms part of the published outputs from a contract between the United Arab Emirates (UAE) Federal Government (Ministry of Energy) and the British Geological Survey (BGS) to produce geological maps, at various scales, of the solid and drift geology of the eastern part of the United Arab Emirates. These maps, which have accompanying Sheet Explanations, are listed below. Geological surveying of the Hatta Sheet was completed in three winter field seasons, carried out between October to December and January to March of 2002-2005. Field data was recorded on transparent overlays on 1:25 000 scale colour aerial photographs, used in conjunction with LANDSAT imagery and 1:50 000 topographical base maps. The field data were transferred onto gridded transparent overlays on georectified LANDSAT images at 1:25 000 scale. The mapping team for the Hatta district consisted of M T Styles, R J Thomas, D I Schofield, K M Goodenough, and E R Phillips, with A R Farrant contributing to mapping of the Quaternary deposits. Petrographic analyses were completed by M T Styles, R J Thomas, E R Phillips and K M Goodenough on samples collected by the mapping team. The Sheet Explanation was compiled by M T Styles. The word ‘district’ is used here to refer to the area represented by the geological map 1:50 000 series sheet Hatta. The grid references in the text are UTM Zone 40 using the Nahrawan datum, given in the form [0419633 2826172]. Symbols in brackets after lithostratigraphic names refer to symbols used on the 1:50 000 series geological map. References to other Sheet Explanations in these series are given by Sheet name and number e.g. (Fujairah Sheet, 50-4)
