Volume 22 • Number 3 (2005) 29 A basic premise of the geodiversity concept recognizes that there is an intrinsic relationship between biological diversity and geological diversity. In principle, the geologic bedrock is viewed as the foundation of the ecosystem. Geologic resources and processes sustain much greater relationships with biotic resources and biosystems than is commonly recognized. T...

Gravitational loading or unloading due to deposition or erosion in sedimentary basins is one of the most common mechanisms responsible for abnormal fluid pressures in geologic formations. This paper examines the integrated response of fluid pressures to both deposition and erosion using vertical one-dimensional numerical models. The modeling results show that vertical loading and unloading of s...

With the development of GIS, its applications concern with different domains, such as geography, mapping, urban, traffic, geology, mine, military and so on. 3D GIS is the research hotspots in the domains of city, geology, mine etc. 3D GIS in city has been developed more quickly, CyberCity, for example is a smart application of 3D GIS, but it is slow in subsurface engineering because of its comp...

Introduction. An important first step in the current Mars exploration strategy [10] is the detection of sites where there is evidence for past or present near-surface water on Mars. This study evaluates the large-scale morphology of spring deposits and the physical processes of their formation, growth, and evolution in terms that relate to (1) their identification in image data, (2) their forma...

Mercury’s quadrangle H02 ‘Victoria’ is located in the planet’s northern hemisphere and lies between latitudes 22.5° N and 65° N, and between longitudes 270° E and 360° E. This quadrangle covers 6.5% of the planet’s surface with a total area of almost 5 million km. Our 1:3,000,000-scale geologic map of the quadrangle was produced by photo-interpretation of remotely sensed orbital images captured...

The United States Department of Energy (DOE) is the lead federal agency for the development and deployment of carbon sequestration technologies. Its mission includes promoting scientific and technological innovations and transfer of knowledge for safe and permanent storage of CO(2) in the subsurface. To accomplish its mission, DOE is characterizing and classifying potential geologic storage res...

In a vast semiarid region of the Baja California Peninsula, remote sensing and GIS techniques were applied to moderate resolution images of Landsat 5 TM to explore the geospatial correlation among the grid aridity index (AI), shapefiles of geologic strata, land use, and geological fractures. A dataset of randomized sample points in a time-series of one hydrologic year along with vector file GIS...

Introduction: The geologic features “shield fields” and “shield plains” (or “shield terrain”) have been used by a number of Venus researchers and authors of Venus geologic quadrangle maps. However, there has been occasional confusion concerning the two terms and the geologic units they define. Stratigraphic interpretation may vary due to the identification of clusters of small shields as either...
