Accurate salt interpretation involves an integration of geology and geophysics. In the practice of salt interpretation and model building in depth imaging, we see two problems that could happen: exclusive geophysical interpretation without geological input and insufficient geological interpretation without understanding how the geophysical data are processed and without evaluating the limit and...

Chief Executive Officers of the National Mining Association (NMA) for the Mine of the Future (MOF) and their prioritized Technology Development Road Map, together with a 2010 Section 11 National Research Council/National Engineering Academy Study, confirmed that boundary detection in coal and metal/nonmetal mining remains a mining technology gap. The National Aeronautical and Space Administrati...

3D geological models become increasingly important and popular recently. But it is too difficult to share the models because of different models come from different modeling software. It is urgent to solve the problem for the unification of data management. Based on it, the paper explains basic construction and architecture if GeoSciML to discuss how to take advantage of this standard and defin...

Vast quantities of natural gas are held in hydrate form in geologic reservoirs in sub-oceanic sediments and arctic permafrost zones (KVENVOLDEN, 1988; SLOAN, 1998), where conditions of high pressure and low temperature are within the hydrate stability region. In 1995, the U.S. Geological Survey (USGS) conducted a study to assess the quantity of natural gas hydrate resources in the United States...

A late Pliocene – early Pleistocene, 2.9–2.0Ma, diatom record from the Antarctic Geological Drilling Program (ANDRILL) MIS drillcore AND-1B is presented. This core, recovered from beneath the Ross Ice Shelf south of Ross Island, comprises multiple diatomaceous-sediment units deposited during interglacial periods with open water over the core site. These represent interglacial phases of orbitall...

In the last decade, Ground-Based Synthetic Aperture Radar (GB-SAR) systems have gained an increasing interest. Many different applications take advantages of the flexibility and capability of such systems to measure deformations with submillimeter precision, map terrains and monitor landslides and other geological phenomena. In literature different focusing algorithms have been proposed. The ai...

The Bonaparte project is a new multi-year bedrock mapping program of the British Columbia Geological Survey (BCGS) concentrating on Mesozoic arc volcanic and plutonic rocks of the Quesnel Terrane in the northeastern part of the Bonaparte Lake (92P) map sheet (Figure 1). The area encompasses a northwest-trending belt of high mineral potential that includes a number of interesting mineral occurre...

We find that the marine 87 Sr/ 86 Sr record shows a significant periodicity of 59.3 ± 3 Myr. The 87 Sr/ 86 Sr record is 171° ± 12°out of phase with a 62 (± 3) Myr periodicity previously reported in the record of marine-animal diversity. These periodicities are close to 58 (± 4) Myr cycles found for the number of gap-bounded sedimentary carbonate packages of North America We propose that these p...

Conservation decisions should be evaluated for how they meet conservation goals at multiple spatial extents. Conservation easements are land use decisions resulting from a combination of social and environmental conditions. An emerging area of research is the evaluation of spatial distribution of easements and their spatial correlates. We tested the relative influence of interacting social and ...

The Geological Survey Office (GSO) undertook a pilot study with the objective of assessing the ability of Survey data to support modern quantitative mineral potential modelling techniques. The Yarrol pilot project was designed to audit digital data sets routinely produced by the GSO, and to provide mineral assessment outputs relevant to both industry and Government decision-making processes. Th...
