Siliciclastic rocks of the upper Byrd Group in the Transantarctic Mountains record rapid denudation and molasse deposition during Ross orogenesis along the early Paleozoic convergent margin of Gondwana. These rocks, which stratigraphically overlie Lower Cambrian Byrd carbonate deposits, are dominated by fresh detritus from proximal igneous and metamorphic sources within the Ross Orogen. Biostra...

What are the issues stratigraphic computing has to deal with? This is a personal view presenting the features of my program Stratify and highlighting trends and aspects that have been discussed in recent publications. Each Harris diagram program has to store its data, either in a data base, or in dynamic structures like linked lists or resizeable arrays. Data storage is the basis of all stratig...

Abstract. The forward stratigraphic simulation approach is applied to predict porosity and permeability distribution. Synthetic well logs from the model served as secondary data control representation in reservoir model. Building a that fits at different locations comes with high levels of uncertainty. Therefore, it critical generate an appropriate framework guide lithofacies associated porosit...

Abstract El Salt (Middle Palaeolithic; Alcoi, Spain) is a key site for understanding the disappearance of Neanderthals in eastern Iberian Peninsula, process that observed along its stratigraphic sequence. To improve our palaeoclimatic context which this took place, we applied UDA-ODA discrimination technique to fossil herpetological assemblages from Stratigraphic Units (SU) Xb (52.3 ± 4.6 ka) a...

During the Late Pleistocene, Palaeo-Ems system (PES) was one of major tributary channels feeding Elbe Palaeovalley (EPV) and formed an important part drainage continental northwestern Europe unglaciated hinterland. In this study, a detailed interpretation high-resolution 2D sub-bottom profiler Boomer grids were used to map overall course submerged PES channel, as well its spatial stratigraphic ...

INTRODUCTION Precambrian rocks in the Tusas Mountains range from nearly monomineralic quartzite, in which the principal result of metamorphism has been simple recrystallization, through locally metasomatized schist and gneiss profoundly modified by potash-rich fluids during the intrusion of pegmatite. Texturally, the rocks range from schist and phyllite containing penetrative and pervasive clea...

The probability that two stratigraphic events are in a particular order in a section in which they occur in sequence is p. Because of finite sampling, statistical techniques are used to calculate the parameters p' and p(l), which express the uncertainty of our knowledge of p; p' is the measured value of the maximum likelihood estimator of p and p(l) is the lower end point of the confidence inte...
