Abstrakt:

The structural position of the Upper Jurassic limestone “klippen” and breccia horizons in Jasenice village surroundings: a part of the Ždánice-Subsilesian or the Silesian Unit?

The structure and geological origin of the Jurassic-Cretaceous limestones in northern Moravia (Valašské Meziříčí and Štramberk towns vicinity) is still under discussion. The limestone “blocks” in Jasenice village are marked as “klippen” or olistoliths and they are a part of flysch nappes in Outer Western Carpathians. While the limestone body at Jasenice is considered to be a part of the Silesian Nappe in published geological maps, the breccias surrounding the limestone are supposed to be a part of the Ždánice-Subsilesian Nappe. According to new geological research, the Jasenice limestone body is a olistolith accompanied with a coarse limestone conglomerates representing olistostrome deposits (gravity slump) situated at the base of the Silesian Nappe.
