  • Fault Surfaces in Earth Volumetric Studio

    There are normally two reasons to create fault surfaces in EVS.  We either just want to display them, or we want to use them to create fault blocks as part of a more complex geologic model.  When we create fault blocks, we are using the surf_cut module and the fault surface is input to the right input port.  There are three main cases to consider with respect to the creation of ...

  • Geochemical modelling of the evolution and fate of metal pollutants arising from an abandoned gold mine tailings facility in Johannesburg

    Analytical techniques were combined with geochemical modelling to study the release mechanisms of pollutants from an abandoned gold mining tailings storage facility near Johannesburg. Inverse modelling of sampled tailings pond water and experimental single extractions using various solutions indicated which combination of naturally occurring leaching solutions were likely to give rise to the ...

  • Method and technique of 3–D dynamic structural evolution modelling of fault basin

    The important and difficult point in the 3–D basin structural evolution modelling is how to make the modelling conform to the real geological process. In this paper, the rectification of formation boundary deformation is implemented by 3–D flexural slip mechanism and shearing mechanism. In compaction correction, by taking account of the phase boundary and diagenetic effect on porosity, a formwork ...

  • The hidden benefits of maturity modelling

    Most 1–D modelling studies are carried out with the explicit objective of calculating maturity and hydrocarbon generation. This focus on bottom–line output has caused most modellers to overlook a major additional value of such studies: the knowledge acquired while building internally consistent geologic models. During model construction one should carefully consider the following factors: events ...

  • Leaching mechanisms of Cr(Vi) from Chromite ore processing residue

    Batch leaching tests, qualitative and quantitative x-ray powder diffraction (XRPD) analyses, and geochemical modeling were used to investigate the leaching mechanisms of Cr(VI) from chromite ore processing residue (COPR) samples obtained from an urban area in Hudson County, New Jersey. The pH of the leaching solutions was adjusted to cover a wide range between 1 and 12.5. The concentration levels ...

  • Local recoverable reserves prediction with block LU simulation

    Prediction of local recoverable reserves is an important problem in ore reserve evaluation. Wide spacing of exploration data leads to unavoidable uncertainty at unsampled locations. Deterministic methods such as kriging cannot explicitly account for this lack of perfect information and equipment selectivity. We present a methodology and software for assessing recoverable reserves at Selective ...

  • Modeling Monomethylmercury and Tributyltin Speciation with EPA’s Geochemical Speciation Model MINTEQA2

    Monomethylmercury (MMHg) is the compound responsible for the majority of fish consumption advisories in forty eight states in the United States of America. These widespread low level (but toxicologically significant) ecological exposures to MMHg result from microbial methylation of atmospherically deposited inorganic mercury in our national waterbodies. Tributyltin (TBT) is an industrially ...
