The Russian Geological Research Institute (VSEGEI) launched the map data at the 34th International Geological Congress (IGC), in Brisbane, Australia, in August 2012. This is the first digital geological map of the whole of the Commonwealth of Independent States (CIS) and neighbouring countries the maps can be viewed via OneGeology.

Are we in for a summer of cracked buildings? It all depends on the weather. Research from the British Geological Survey (BGS) has highlighted the importance of rainfall and temperature on the incidence of clay shrink-swell, a precursor to subsidence, in the UK. For many, the cool, wet conditions we have experienced so far this summer may be just what is needed to keep their house in order.
New research by the BGS - published this week in the Proceedings of the Geologists Association - suggests that the low rainfall of the last 2 years has increased the susceptibility of buildings to subsidence due to clay 'shrink-swell' . The research takes into account the effect of rainfall and temperature, and despite the very wet weather experienced since April, there is still an increased potential for clay soils to shrink and swell this year. If this occurs, it is likely to lead to an increase in subsidence.
Scientists have produced a new free map app of the soils of Great Britain. The app, mySoil, also enables the general public to upload information about the soil where they live, helping to improve our knowledge about the properties of soils and the vegetation habitats that they provide.
Using mySoil you can view a map of soil parent material - the underlying geological material - click on an area to get information about soil depth, texture, pH and organic matter content, and explore vegetation habitat data across the UK.
mySoil, produced by the NERC British Geological Survey (BGS) and the NERC Centre for Ecology & Hydrology (CEH), was launched at the Times Cheltenham Science Festival on 14 June 2012.
mySoil, for iPhones and iPads, is for anyone with an interest in the soil of Great Britain, including allotment owners, farmers and agricultural specialists, gardeners, schools and college students, environmentalists and land use planners. We encourage land users, especially in cities, to send us descriptions and pictures of their soil. The public can play a big role in contributing to soil science data, for urban areas in particular, where the data is limited.
You are probably aware that the UK is an active member of the Integrated Ocean Drilling Program (IODP) but has never participated as a member of the International Continental Scientific Drilling Program (ICDP).As geologists and geoscientists (and as emphasised in recent forward looks on our science www.ukgeoscience.org.uk ) it is essential that we have access to key geological sections which can be well constrained in terms of time and formation. This allows us to determine the processes of global change that affect the Earth and to understand the controls on resource development. In addition, through instruments in the drill holes we can monitor and model natural hazards and fluid-related biological processes in the sub-surface.
New research has revealed that some events in Earth's history happened more recently than previously thought.
Scientists from the British Geological Survey and the Massachusetts Institute of Technology, publishing this week in the journal Science, have refined the data used to determine how much time has passed since a mineral or rock was formed.
They report uranium isotopic composition of minerals, used to date major geological events, which are more accurate than previously published.
The major effect of this is to reduce previous age determinations by up to 700 000 years.
