The Arizona Geological Survey has released its first geologic map database for aggregate resource assessment in the Phoenix metropolitan area. This map product will provide the basis for local and county planning and zoning authorities to make informed decisions regarding conservation and management of aggregate resources.
Directory of Mines and Quarries. BGS has been collecting location and other information about operating mineral workings in the UK since its formation in 1835. The current publication summarising this data is the Directory of Mines and Quarries (DMQ), Eleventh Edition, 2020. The DMQ is derived from data held in the BritPits database.
The South Dakota Department of Environment and Natural Resources provides an interactive map of over 6,000 sand, gravel, and construction aggregate mining operations in South Dakota.
We play an active role on the seabed around England, Wales and Northern Ireland, including offshore energy, marine aggregates, and cables and pipelines.
Natural aggregate is widespread throughout the conterminous United States, but the location of aggregate is determined by geology and is non-negotiable. Natural aggregate is in short supply in the Coastal Plain and Mississippi embayment, Colorado Plateau and Wyoming Basin, glaciated Midwest, High Plains, and the non-glaciated …
Licences for marine aggregate dredging fall into seven broad geographical regions around the UK coastline, the majority of them concentrated off the East and South coasts of England. Other licence areas are located in the Bristol Channel and in the Irish Sea.
The Aggregates Levy is an environmental tax that was introduced in 2002 to reduce the extraction of fresh aggregate (rock, sand and gravel used as bulk fill in construction) and encourage ...
This report is accompanied by maps of the English regions that show the extent of aggregate resources located outside national parks, AONBs and selected other national and international designations.
The findings of this report align with the path the Ministry is on to modernize and improve aggregate resource management in Ontario. The Ministry made legislative and regulatory changes under the Aggregate Resources Act and established four new Aggregate Resources of Ontario Provin-cial Standards between 2019 and 2022.
In the UK, four areas have been identified as potentially viable for the commercial extraction of shale gas: the Carboniferous Bowland–Hodder area in north-west England (Lancashire and the Midlands) the Carboniferous Midland Valley in Scotland. the Jurassic Weald Basin in south England. the Wessex area in south England.
The purpose of this paper is to assess the aggregate rocks in Tadla-Azilal region and to delineate the areas with aggregate resources. The suitable site selection is performed using the GIS ...

MNRF is proposing regulatory changes to Ontario Regulation 244/97 under the Aggregate Resources Act to expand the list of changes that can be made to site plans without ministry approval (subject to conditions) and proposing a policy that would provide direction for changes to licences, permits and site plans where ministry approval is …
The underpinning concept behind the Managed Aggregate Supply System is that Mineral Planning Authorities which have adequate resources of aggregates make an appropriate contribution to national as well as local supply, while making due allowance for the need to reduce environmental damage to an acceptable level.

Details. Aggregate minerals surveys, normally undertaken at 4-yearly intervals since 1973, but at 5 yearly intervals for the current and previous survey, provide an in-depth and up-to-date ...
In 1973 House Bill 1529 charged the Colorado Geological Survey to "contract for a study of the commercial mineral deposits in the populous counties of the state in order to identify and locate such deposits. Such study shall be of sand, gravel, and quarry aggregate, and shall be completed on or before July 1, 1974, and shall include a map or maps of the state …
Mineral resources are defined as natural concentrations of minerals or, in the case of aggregates, bodies of rock that are, or may become, of potential economic interest due to their inherent properties (for example the high crushing strength of a rock or its suitability for use as an aggregate). The mineral will also be present in sufficient ...
Aggregate Industries, part of the Holcim Group, is a leading supplier of sustainable construction materials with over 200 sites and 3,700 employees across its divisions in the UK.
This report is one of two outputs from a project entitled 'Aggregate resource alternatives: Options for future aggregate minerals supply in England'. It accompanies eight aggregate mineral resource maps at 1:250 000 scale, one for each region in England (the South East and London have been combined on one map). The aims of …
The Alberta Sand & Gravel Deposits with Aggregate Potential interactive map displays sand and gravel deposits information with aggregate resource potential and is based on data and maps published by the Alberta Geological Survey. Base data layers are included for additional context and are supplied by Alberta Environment and Parks as …
