Abstract
Necessary and sufficient conditions for the formation of trapped surfaces in a class of nonspherical systems are proven. Massive singularities, if they exist in the geometries discussed, are always surrounded by apparent horizons. Milder singularities that are strongly nonspherical might be naked. Implications concerning the validity of the hoop conjecture are discussed.Keywords
