A new dichotomy theorem for a space of probability, Radon measures is proved. Some applications of this result are given. In this paper we investigate some properties of measures on compact spaces. We prove a new dichotomy theorem for a space of probability, Borel and regular measures on a compact space (Theorem 2.2). Roughly speaking it says that if M is a compact, convex set in the space of measures then there either exists a point in M with a small local base, or there exists a point in M with a large Maharam type. Thus our theorem gives a connection between topology and measure theory. It can be also viewed as a purely topological or purely measure theoretical statement. The idea of this note was inspired by an attempt of generalizing Theorem 4.3 in [3], which was successfully done (Corollary 3.7). As a corollary to our main theorem, we give a dierent proof of a theorem due to
