Abstract
We prove that for any compact zero-dimensional metric space on which an infinite countable amenable group acts freely by homeomorphisms, there exists a dynamical quasitiling with good covering, continuity, F{\o}lner and dynamical properties, i.e to every we can assign a quasitiling of (with all the using the same, finite set of shapes) such that the tiles of are disjoint, their union has arbitrarily high lower Banach Density, all the shapes of are large subsets of an arbitrarily large F{\o}lner set, and if we consider to be an element of a shift space over a certain finite alphabet, then the mapping is a factor map.
