Numerical simulation of supercritical brine flow in a porous medium during the degassing of a magma chamber with consideration of the transport and quartz precipitation is performed. It is shown that the precipitation of quartz and the accompanying decrease in permeability reduce the dimensions of the concentrated brine lens formed above the chamber. The effect of hydraulic fracture of rocks on the lens formation is studied. A nonstationary degassing regime is revealed, which is associated with a periodic increase and decrease in permeability due to fracturing and quartz precipitation. The numerical results are in agreement with the geological data on the structure of copper deposits.
