abstract = {A tephra-rich cherty-clayey Famennian succession within the major Brzeźnica olistostrome in the Bardo Mountains, Central Sudetes, SW Poland, preserves a record of the lost ocean later incorporated into the Variscan orogenic belt. Fluctuating but mostly oligotrophic regimes and low primary production levels were influenced by weak upwelling below the perennial oxygen minimum zone, which controlled the interplay between biosiliceous and siliciclastic deposition in the oceanic basin, with episodic oxygen deficiency. The Hangenberg Black Shale has been identified in this oceanic setting based on its characteristics described worldwide (including mercury enrichments). A tectonic uplift of the sediment source area near the Devonian- Carboniferous boundary, recorded in the distinguishing provenance signal of old continental crust, was paired with a global transgression, anoxia, and volcanic episode in an interglacial interval. Assuming paleogeographic affinity with the Bavarian facies of the Saxothuringian terrane, we interpret the allochthonous sediments as part of an accretionary prism that was gravitationally redeposited into the late orogenic basin in front of advancing Variscan nappes. The oceanic basin parental to the Bardo pelagic succession is therefore thought to represent a tract of the waning Saxothuringian Ocean in the Peri-Gondwanan paleogeographic domain that was eventually subducted beneath the Brunovistulian margin of Laurussia. The sediments of the Bardo Ocean basin also include a distal record of Famennian explosive volcanic activity that was likely related to a continental magmatic arc whose remnants are preserved as the Vrbno Group of the East Sudetes. © 2022, Geological Society of America Bulletin.

abstract = {In this work, we combined a three-point problem with Delaunay triangulation to determine the average orientation of a sub-horizontal contact lying within the Kraków-Silesian Homocline, Poland.

The approach presented involved computing the local orientation of Delaunay triangles that represented the investigated surface. A C++ application was developed to compute the required figures, to which we added computer code that is open source and freely available. The pre-processing stage required the removal of collinear configurations that contributed to floating-point arithmetic inaccuracies. We then assigned dip angle and direction to the Delaunay triangles and performed a stereographic projection of the unit normal vectors. For statistical analysis, we conducted inertia moment analysis and followed the mean vector approach. As a part of exploring the orientation data—and as a way of achieving better consistency with initial stereonet results—we used several clustering algorithms: k-means, k-medoids and hierarchical. We indicated that the Euclidean distance could be beneficial for extracting the sub-population assumed to represent the regional trend. We concluded that considering four clusters and the combination of the Euclidean distance and Ward linkage methods gave us the best extraction results for the dominant orientation. We identified limitations to the proposed approach relating to the lack of statistical information on the calculated orientations and suggested potential extensions to the research, including mixture models and investigation of spatial patterns. © 2019 Elsevier Ltd},
