Soil Texture and Structure
Soil Texture Most soils are far from uniform and contain particles of different sizes. Soil texture refers to the proportions of different particle sizes. Texture […]
Contact, or Thermal, Metamorphism
Contact metamorphism, or thermal metamorphism, occurs in Earth’s upper crust (low pressure), when rocks immediately surrounding a molten igneous body are “baked” (high temperature). Because […]
The giant Jiaodong gold province: The key to a unified model for orogenic gold deposits?
Introduction Groves et al. (1998), following Gebre-Mariam et al. (1995), defined the term orogenic gold deposit to obviate the necessity to refer to a wide […]
Numerical evaluation of new Austrian tunneling method excavation sequences: A case study
Introduction Tunnels provide a feasible alternative to cross through the physical barriers or water body. With the rapid development of the world, the utilization of […]
Effect of discrete fibre reinforcement on soil tensile strength
Introduction Compared with compressive or shear strength, tensile strength of soil is basically assumed to be zero, or insignificant in geotechnical engineering practice because of […]
Stabilizing soft clay using geo-foam beads and cement bypass dust
Introduction Expanded polystyrene (EPS) geo-foam blocks are used as a lightweight fill in a wide range of geotechnical applications. The primary function of geo-foam is […]
Geoelectrical monitoring of simulated subsurface leakage to support high-hazard nuclear decommissioning at the Sellafield Site, UK
Introduction Whilst modern geophysical methodology is increasingly applied at nuclear legacy sites worldwide, the full potential of near-surface geophysics has yet to be fully recognized […]
3D geological modelling of a complex buried-valley network delineated from borehole and AEM data
Introduction Buried and open tunnel valleys are common features in former glaciated regions (Kehew et al., 2012, van der Vegt et al., 2012). The buried […]
3D geological modeling for mineral resource assessment of the Tongshan Cu deposit, Heilongjiang Province, China
Introduction Three-dimensional geological modeling (3DGM) is a developing technology for geological studies, mineral resource exploration, and quantitative estimation of mineral resources (Houlding, 1994; Mallet, 2002; […]
