  • A MODEL OF OSCILLATORY ZONING IN SOLID SOLUTIONS GROWN FROM AQUEOUS SOLUTIONS: APPLICATIONS TO THE (BA,SR)SO4 SYSTEM 
    L'Heureux I.; Jamtveit B. (2002)
    Barite-celestite crystals can be synthesized from aqueous solutions during counter-diffusion in a gel column connecting two reservoirs. It is known that such crystals may exhibit oscillatory zoning, whereby the barium ...
  • FORMATION OF SAUCER-SHAPED SILLS 
    Malthe-Sørenssen A.; Svensen H.; Jamtveit B.; Planke S. (2004)
    We have developed a coupled model for sill emplacement in sedimentary basins. The intruded sedimentary strata are approximated as an elastic material modelled using a discrete element method. A non-viscous fluid is used ...
  • MODELING HYDROFRACTURE 
    Flekkøy E.G.; Malthe-Sørenssen A.; Jamtveit B. (2002)
    We have developed a model to simulate the formation and evolution of hydraulic fractures. The model relies on a discrete spring network representation of the fracturing media and a continuum description of the fluid pressure ...
  • NOISE AND OSCILLATORY ZONING OF MINERALS 
    Holten T.; Jamtveit B.; Meakin P. (2000)
    Oscillatory mineral zonation is usually associated with crystal growth in an open system, either a hydrothermal system or a melt after a period of magma mixing or degassing. Such systems may be driven sufficiently far from ...
  • TRANSIENT DISSOLUTION PATTERNS ON STRESSED CRYSTAL SURFACES 
    Koehn D.; Dysthe D.K.; Jamtveit B. (2004)
    We present an experimental investigation on the dissolution of uniaxially stressed crystals of NaClO3 in contact with brine. The crystals are immersed in a saturated fluid, stressed vertically by a piston and monitored ...
