Abstract

The paper introduces a new type of arenite concretions (max. 40-50 cm in diameter). Spheroidal concretions with an axial cylindrical channel (1-6 cm in diameter) resulted from the levigation of the concretion centre consisting of soft fusiform clasts with a clayey-carbonate composition. The concretions are hosted by a level of Badenian sandstones and microconglomerates (about 10-m thick) which occur in the place called “Groapa cu Piersici” (Cheia, Turda).
