Opis:
The object of the investigation is the so called Madonna Jackowa, or St. Hyacinthus's Madonna, a gothic alabaster figurine dated from the XIVth century. The purpose of the investigation is to provide an answer to the question whether Madonna Jackowa was made of native alabaster. Samples of alabaster from five various quarries located along the line Cracow-Lvov as well as in Lower Silesia were analyzed and the content of trace elements was compared with that of the sculpture. The determination of trace elements was carried out by means of the instrumental neutron activation analysis.

Opis:
The entrenched Odra palaeovalley, cut into the bedrock of the distal margin (forebulge basal unconformity) of the Moravian Carpathian Foredeep (peripheral foreland basin) is filled with an almost 300 m thick pile of Miocene deposits. The directon of the valley (NW-SE to NNW-SSE) has been controlled by faults subparallel with the system of “sudetic faults“. The sedimentary succession consists of 5 facies associations/depositional environments, which are interpreted (from bottom to top, i.e. from the oldest to the youngest) as: 1 - colluvial deposits to deposits of alluvial fan, 2 - deposits of alluvial fan, 3 - fan-delta deposits, 4 - shallow water delta to nearshore deposits and 5 - open marine deposits. This fining-up and deepening-up succession reveals the following: the formation of the new flexural shape of the basin; deep erosion connected with uplift and tilting of the forebulge and reactivation of the NW-SE trending basement faults; the Early/Middle Miocene sea level fall; alluvial deposition mostly driven by tectonics and morphology; forebulge flexural retreat; Middle-Miocene sea level rise; back-stepping of valley infill; marine invasion during the Early Badenian with shift of the coastline further landward of the pallaeovalley. Tectonics related to contemporary thrusting processes in the Western Carpathians are assumed to be the dominating factor of the studied deposition at the expense of eustatic sea level changes. Provenance studies have proven that the pre-Neogene basement (i.e. the Early Carboniferous clastic “Culmian facies” ofthe Moravian-Silesian Paleozoic) represents an important source for the conglomerates and sands, which volumetrically dominate in the palaeovalley infill. However, they also showed, that the deposits of the earlier Carpathian Foredeep Basin sedimentary stage (Karpatian in age?) covered the area under study and were eroded and resedimented into the palaeovalley infill.
