This paper discusses the concept of marked stationary Gibbs processes which
are globally defined on the continuous state space R-nu and an arbitrary m
ark space M. The framework is the theory of superstable potential Gibbs pro
cesses of RUELLE [13]. The maximum pseudo - likelihood estimator of marked
potentials and its strong consistency are considered. Finally the asymptoti
c normality of maximum pseudo-likelihood estimators for the finite-range ma
rked potential case is shown, which is an extension of JENSEN & KUNSCH (199
4).
