  The frustrated spin-one-half Heisenberg model on triangualr and Kagome
Lattices is mapped onto a single specis of fermion carrying statistical flux.
The corresponding Chern-Simons gauge theory is analyzed at the Gaussian level
and found to be massive. This provides a new motivation for the spin-liquid
Kalmeyer-Laughlin wave function. Good overlap of this wave function with the
numerical ground state is found for small clusters.
