Have you tried just attaching resistors to the amplifier, in place of the
cable and geophone? If there are still spikes, then the cable is not
involved.
Have you tried a short cable between the geophone and the amplifier?
Don't worry about the local ground noise, just look for the spikes. The
length of the cable may be a critical factor, but not necessarily. If there
are spikes with a short cable but not with just resistors, then you
can experiment with the ground attachments and cable type with
short cables until you find something that works.
