We consider a completely stationary spatio-temporal point process. This process is transformed into two stationary marked point processes by taking the times or locations as marks. For these marked point processes mark variograms can be defined. These variograms yield valuable information about the spatio-temporal behaviour of the original process. We give their forms for some simple spatio-temporal point processes. Then we study statistical problems. The used ratio-estimator has a form that makes it possible to ignore partially inhomogeneities and edge-effects. Some examples show the explorative power of the mark variograms.
