What are "extremal invariant measures"?

Currently, I'm researching in the field of interacting particle systems. In this context, I don't understand the terminus "extremal invariant measures".
Is anyone used to this expression or knows a definition?
Thank you very much!
PS: The relevant paper is the following: COX, J.T. and GREVEN, A.: On the Long Term Behavior of Some Finite Particle Systems. Probability Theory Related Fields 85, 1990, pp. 195237. There you find the expression "extremal invariant measures" already in the summary.
