    In: Geological Society special publication
    Description / Table of Contents: This volume brings together a collection of papers that summarize current ideas and recent progress in the study of granite-related mineralization systems. They provide a combination of field, experimental and theoretical studies. Papers are grouped according to the main granite-related ore systems: granite-pegmatite, skarn and greisen-veins, porphyry, orogenic gold, intrusion-related, epithermal and porphyry-related gold and base metal, iron oxide copper gold (IOCG), and special case studies. The studies provide a broad spread in terms of both space and time, highlighting granite-related ore deposits from Europe (Russia, Sweden, Croatia and Turkey), the Middle East (Iran), Asia (Japan and China) and South America (Brazil and Argentina) and spanning rocks from Palaeoproterozoic to Miocene in age.

    Notes: In this work we present structure factors and triplet direct correlation functions extracted from extensive Monte Carlo simulations for a binary mixture of hard spheres. The results are compared with the predictions of two integral equation theories, namely, a recently proposed extension to mixtures of Attard's inhomogeneous integral equation approach, and Barrat, Hansen, and Pastore's factorization ansatz. In general, both theories yield acceptable estimates for the triplet structure functions, though, by construction, the inhomogeneous integral equation theory is more suited to furnish triplet distribution function results, whereas the factorization ansatz provides a more handy approach to triplet direct correlation functions. © 2002 American Institute of Physics.

    Notes: An approach to calculate the triplet structure of a simple liquid, that was proposed some years ago by Barrat, Hansen, and Pastore [Phys. Rev. Lett. 58, 2075 (1987)] has been tested in the binary case. This approach is based on a factorization ansatz for the triplet direct correlation function c(3); the unknown factor function is determined via the sum rule relating c(3) and the pair direct correlation function which is the only input information of the system that is required in this formalism. We present an efficient and stable numerical algorithm which solves the six (partly coupled) integral equations for the unknown factor functions. Results are given for the case of a binary hard-sphere mixture and complemented by computer simulation data. © 2000 American Institute of Physics.

    Notes: The inhomogeneous integral equation proposed by Attard for the study of triplet correlations [J. Chem. Phys. 91, 3072 (1989)] has been generalized to multicomponent systems. Defining one of the particles of a triplet as the source of an external field, the three particle distribution functions for the mixture are calculated using the inhomogeneous Ornstein–Zernike equation, an approximate closure relation and the Triezenberg–Zwanzig relation. The proposed theory performs satisfactorily for asymmetric mixtures of Lennard–Jones fluids for which other approximations at the two particle level tend to be rather inaccurate. © 2001 American Institute of Physics.

    Notes: The structure of 3:3 and 1:3 electrolyte solutions at various concentrations and several cation/anion size ratios has been analyzed in terms of triplet and pair correlation functions, by means of simulation and a triplet integral equation theory derived from the inhomogeneous Ornstein–Zernike equation. The interaction model consists of a truncated and shifted Coulomb plus the Ramanathan–Friedman repulsive core. Concentration and size and charge asymmetry are found to induce changes in the triplet structure beyond those predicted by the simple superposition approximation, which are, however, correctly reproduced by the triplet integral equation. © 2002 American Institute of Physics.

    Notes: We present an extensive integral equation study of a simple point charge model of water for a variety of thermodynamic states ranging from the vapor phase to the undercooled liquid. The calculations are carried out in the molecular reference-hypernetted chain approximation and the results are compared with extensive molecular dynamics simulations. Use of a hard sphere fluid as a reference system to provide the input reference bridge function leads to relatively good thermodynamics. However, at low temperatures the computed microscopic structure shows deficiencies that probably stem from the lack of orientational dependence in this bridge function. This is in marked contrast with results previously obtained for systems that, although similarly composed of angular triatomic molecules, do not tend to the tetrahedral coordinations that are characteristic of water.© 1999 American Institute of Physics.

    Notes: The analytical expression for the frequency of the unperturbed radial electrostatic lower-hybrid (LH) ray oscillations is derived, which constitutes the first analytically calculable result in nonlinear LH ray dynamics. For LH current drive (CD) conditions, and after comparing the frequency of the unperturbed LH ray motion with the frequency of the ripple perturbation, it is concluded that the electrostatic LH ray dynamics is generally regular in cylindrical plasmas with magnetic ripple. It is also found analytically that including the magnetic ripple in ray-tracing calculations does not lead to a final closure of the spectral-gap problem for LHCD in circular-poloidal-cross-section tokamaks having sufficiently low electron density, in addition to a high enough aspect ratio and safety factor, in which case electrostatic LH wave propagation turns out to be independent of the latter, and the unperturbed LH ray oscillations become basically linear. This is an important null result that helps to show that the conventional ray-tracing picture widely used in LHCD modeling (that is to say, a standardly coupled LH spectrum propagating according to geometrical optics in an established tokamak equilibrium) is not to be taken as final. The analysis presented, carried out within an explicitly Hamiltonian formalism and addressing the role of resonances between the frequency of the unperturbed LH ray motion and the frequencies of the perturbations due to magnetic ripple and toroidicity, is detailed and careful, with analytical results and conclusions being supported by numerical calculations. © 1999 American Institute of Physics.
