National resources of many industrial minerals may seem so large that stocktaking appears unnecessary, but the demand for minerals and for land for all purposes is intensifying and it has become increasingly clear in recent years that regional assessments of the resources of these minerals should be undertaken. The publication of information about the quantity and quality of deposits over large areas is intended to provide a comprehensive factual background against which planning decisions can be made. Sand and gravel, considered together as naturally occurring aggregate, was selected as the bulk mineral demanding the most urgent attention, initially in the south-east sf England, where about half the national output is won and very few sources of alternative aggregates are available. Following a short feasibility project, initiated in 1966 by the Ministry of Land and Natural Resources, the Mineral Assessment Unit began systematic surveys in 1968. The work is now being financed by the Department of the Environment and is being undertaken with the cooperation of the Sand and Gravel Association of Great Britain. This Report describes the resources of sand and gravel of 100 km of country to the east of Chelmsford, shown on the accompanying 1:25 000 resource map TL 70. The survey was conducted by the late J. D. Ambrose, by A. R. Clayton and by N. E. Bradbury in 1968-69; additional survey was carried out by M. R. Clarke in 1972. The results of a feasibility study conducted in the area during 1967 are also included in this Report. The work is based upon a geologica1 survey at the 1:lO 560 scale, by C. R. Bristow and R. D. Lake (East Anglia and South-East England Field Unit) in 1966-70. Mr J. W. Gardner CBE (Land Agent) has been responsible for negotiating access to land for drilling. The ready cooperation of landowners and tenants is gratefully acknowledged.
