In Geosoft GXF format it is known by the name "*Albers Equal-Area Conic" indicating that it isn't an EPSG projection.
GeoTIFF: I have incorporated a version that corresponds to the GeoSoft, Intergraph and PCI definitions, and mostly like the second option here, but using NatOriginLat, and NatOriginLong rather than FalseOriginLat/FalseOriginLong or NatOriginLat/CenterLong as sometimes is done. This doesn't match the earlier AlbersEqualArea = LinearUnits + StdParallel1 + StdParallel2 + CenterLong + NatOriginLat + FalseEasting + FalseNorthing proposition form the GeoTIFF mailing list.
