Abstract

"The orientation of crinoid detritus is used to deduce a current pattern in the Carboniferous limestone of the Benbulbin area, County Sligo, in northwest Ireland. Experiments show that orientation of elongated particles by a unidirectional current will be aligned in several maxima. In the investigated environment orientation around the 'b' direction dominates. The frequency diagrams of orientation measurements are best described by harmonic analysis."
