1. A computer-implemented method of inferring stratigraphy over a volume of seismic information, the method being implemented in a computer system that includes one or more physical processors, the method comprising: obtaining seismic information related to a subsurface volume, the seismic information including amplitude information indexed by (i) a two-dimensional position in a surface plane of the subsurface volume, and (ii) a metric related to seismic depth of the subsurface volume; determining a warping function for the seismic information that re-indexes the amplitude information to (i) a two-dimensional position in the surface plane of the subsurface volume, and (ii) a metric related to relative geologic age; obtaining a flat stratiqraphic volume in which flat, horizontally layered horizons have been defined, wherein the horizons are defined in the flat stratigraphic volume with a regular spatial frequency that has a greater resolution than the resolution of horizons that are resolvable within the obtained seismic information; and applying an inverse of the warping function to the flat stratigraphic volume to generate a proxy stratigraphic volume that is usable in subsequent seismic modeling related to the subsurface volume.
