Geology is the base for highways and tunnels construction. With the fast development of national highway construction, highway tunnel construction project are more and more complex. The completeness and accuracy are essential for the planning, design and construction of projects, while the ground information is quite poor in systematic, reliable and timely aspects. Therefore, the development of...

This paper describes a tablet-based application to be used by novice geologists for taking geological measurements during fieldwork. The application was implemented on an iPad2. Both our app and the FieldMove Clino iOS app (from Midland Valley, a well-known geophysics software company) were compared with ground truth measurements taken using a Silva compass clinometer. The results show that the...

This paper reports a nonlinear controlling function of geological features on magmatic-hydrothermal mineralization, and proposes an alternative method to measure the spatial relationships between geological features and mineral deposits using multifractal singularity theory. It was observed that the greater the proximity to geological controlling features, the greater the number of mineral depo...

During 2000-2001, the U.S. Geological Survey (USGS), in cooperation with the Ocean Modeling and Prediction Division of the U.S. Naval Oceanographic Office (NAVOCEANO), constructed tidal gages at the East Pearl River at CSX Railroad near Claiborne, Mississippi, at the Rigolets at CSX Railroad near Rigolets, Louisiana, and at the Chef Menteur Pass at CSX Railroad at Chef Menteur, Louisiana, to co...

Atmospheric carbon dioxide (CO2) data for the last 420 million years (My) show long-term fluctuations related to supercontinent cycles as well as shorter cycles at 26 to 32 My whose origin is unknown. Periodicities of 26 to 30 My occur in diverse geological phenomena including mass extinctions, flood basalt volcanism, ocean anoxic events, deposition of massive evaporites, sequence boundaries, a...

Again this year, abstracts from the annual Atlantic Universities Geological Conference (AUGC) are published in Atlantic Geology. This provides a permanent record of the abstracts, and also focuses attention on the excellent quality of the presentations and posters and the interesting and varied geoscience that they cover. The abstracts are published with fi nancial assistance from APICS. THE ED...

Terrestrial impact structures are geological and geomorphological features with particular importance to understand the history and evolution of the planet. Impact structures are scattered around the world but in many countries these features are under threat, essentially due to anthropic factors. Impact structures with higher scientific value should be considered as geological heritage and, co...

Hazard analysts and risk managers of natural perils, such as earthquakes, landslides and floods, need to access information from sensor networks surveying their regions of interest. However, currently information about these networks is difficult to obtain and is available in varying formats, thereby restricting accesses and consequently possibly leading to decision-making based on limited info...
