Opis:	Following Alspach and Parsons, a metacirculant graph is a graph admitting a transitive group generated by two automorphisms $\rho$ and $\sigma$ , where $\rho$ is $(m,n)$ -semiregular for some integers $m \ge 1$ , $n \ge 2▫$, and where ▫$\sigma$ normalizes $\rho$ , cyclically permuting the orbits of $\rho$ in such a way that $\sigma^m$ has at least one fixed vertex. A half-arc-transitive graph is a vertex- and edge- but not arc-transitive graph. In this article quartic half-arc-transitive metacirculants are explored and their connection to the so called tightly attached quartic half-arc-transitive graphs is explored. It is shown that there are three essentially different possibilities for a quartic half-arc-transitive metacirculant which is not tightly attached to exist. These graphs are extensively studied and some infinite families of such graphs are constructed.
