GENERAL LITHOLOGY OF THE MOJCZA SECTION The M6jcza Limestone Formation, composed predomi- nantly of calcarenites, is about 8 m thick. Their basal part is represented by sandy limestones because of a large admixture of quartz grains. This part of the section is medium- to thick-bedded with sharp, erosional contacts between layers.

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
Sediment subjected to storm–induced reworking events that favoured the condensetion. Taking into consideration the presence of the limestone intraclasts within the phosphorite conglomerate, it seems possible that nearby might have existed raised energy shoals colonized by echinoderms and other organisms might have existed.

The deposition of limestones from the Mójcza section took place on the outer part of drowned isolated carbonate platform of temperate water setting in uniform sedimentary conditions with low accumulation rate. This environment, located in the upwelling current activity area, was favourable for phosphatization of sediment.
Four kinds of robust elements have been recognised in Amorphognathus quinquiradiatus Moskalenko, 1977 (in Kanygin et al. 1977) from the early Late Ordovician of Siberia, indicating that at least 17 elements were present in the apparatus, one of them similar to the P 1 element of the Early Silurian Distomodus.The new generic name Moskalenkodus is proposed for these conodonts with a ...

Abstract The Gillberga quarry in northern Öland provides a c. 16 m thick sequence through middle Volkhov to upper Kunda (mid-Arenig to early Llanvirn) beds. The section has been sampled for conodonts and its temporal faunal changes have been investigated on the basis of fiftynine samples yielding over 300,000 conodont elements. Conodont zones earlier recognized in south-central Sweden and ...

Abstract. On the basis of the first data on the taxonomic composition and stratigraphic distribution of conodont assemblages in the Borehole Gavrilov Yam-1 section (central part of the Moscow Syneclise), its biostratigraphic subdivision is proposed with specification of some formations previously substantiated by finds of acritarchs and benthic faunal assemblages.

The Mójcza Fm was deposited in stable environments on submerged platform separated from the source of terrestial material and represents mainly the first stage of carbonate sedimentation during Ordovician related to sea-level highstand after Llandwirn transgression.
