Limestone. It was first reported by ZEUSCHNER (1869) from Miedzygorz and identified as Ordovician in its type locality by GORICH (190I). The M6jcza Limestone (PI. I), is about 8 m in thickness in Mojcza, and is strongly sandy close to its base, with rare glauconite grai ns contributing to the clastic frac tion there, higher up it becomes

Permian Period

Lower Permian limestone reefs are found in the western and southern Urals of eastern Europe. Basin sedimentation. Cratonic shelf sedimentation in low paleolatitudes during Permian time was characterized by the gradual withdrawal of shorelines and the progressive increase in eolian (wind-transported) sands, red beds, and evaporites.

limestone sedimentation mojcza

Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.

Measured rates of sedimentation: What exactly are we …

Rate of sedimentation is essentially a ratio – an amount of sedimentation per length of time – therefore the obvious strategy to use in determining it is first to measure the amount and the time independently, then to combine the values. The amount can be measured in terms of thickness or volume or mass per unit area.

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.

The paper deals with sedimentary evolution of the condensed Ordovician sequence outcropping in Mojcza village, near Kielce (Central Poland), basing on microfacies analysis. The occurrence of fossils, their preservation and mineral composition enabled the author to distinguish five microfacies types. The Mojcza section is generally composed of …

Sedimentation was controlled by eustatic changes. Coincident with maximum Cretaceous flooding, anoxic events favored accumulation of organic matter at the sea bottom resulting in the best petroleum source rocks in northern South America. From Venezuela to Ecuador, pelagic shale and pelagic fine-grained limestone sedimentation prevailed.

Condensation and phosphatization of the Middle and

Sedimentation on the deep shelf changed to aerobic probably due to intense thermohaline circulation. Euxinia in the water column occurred directly during the time associated with the second pulse of the mass extinction with a termination of the end-Ordovician glaciation and sea level rise just at the Ordovician/Silurian (O/S) boundary.
