ABSTRACT Geoheritage documentation is critical for the academic community, and thus incurs an expense to the general public, who may or may not feel the need to fund such an “academic” database. Fortunately, this documentation helps foster appreciation of geosites within a geotouristic framework and can inspire a nationalistic sense of pride, thus bringing about an economic incentive to countries actively involved in geoheritage research and documentation. Yet there remains a prejudice within academia that geoheritage is a descriptive field, is arbitrarily qualitative, and lacks the capacity to create new and important scientific discoveries. We present herein a description and discussion of the results of applying “cutting-edge” science in a geoheritage framework with ample examples from Greece and two case studies of its application. The first of these is The Aliakmon Legacy Project of Northern Greece that necessitated modern documentation to preserve its heritage base when plate tectonic global geoheritage localities were flooded. The second summarizes the geologic history of the Meteora World Heritage Site with an emphasis on how its long complex geologic history ultimately resulted in the Byzantine Monastic community. We propose this paper as a discussion model for the integration of primary geologic research with cultural heritage localities and emphasize that these promise to elevate geoheritage studies to a scale critical for documentation of human civilization itself. It is our opinion that geoheritage is capable of becoming a dynamic field of study in which documentation and preservation expands to integrate renewed multidisciplinary research that in turn comprises the scientific foundation of a “new” cutting-edge geologic field of study.

Abstract: The total throw across a fault zone may not occur entirely on a single fault strand but may be distributed onto several strands or may be accommodated by distributed deformation within or adjacent to the fault zone. Here we conduct a quantitative analysis of the partitioning of throw into three components, the throw accommodated by: (a) the largest fault strand; (b) subsidiary faults; and (c) continuous deformation in the form of bed rotation in sympathy with the fault downthrow direction. This analysis is applied to seven seismic-scale fault zones at outcrop resolution (maximum throw 50 m) that were mapped over a four-year period during open-cast lignite mining within the late Miocene–Pliocene Ptolemais Basin, West Macedonia, Greece. The analysis shows that the fault zones offsetting the lignite–marl sequence are more localized at higher throws with progressively more of the total throw accommodated by the largest fault strand. Normal drag, which can account for up to 12 m of the total throw, accommodates a lower proportion of the total throw on larger faults. It appears that initial fault segmentation is the main control on the degree of, and spatial variation in, fault throw partitioning.

Abstract: The boundaries between pairs of adjacent fault segments within normal fault arrays define a spectrum of structures, from relay ramps where the length of overlap between the fault segments is much larger than the separation, through low aspect ratio (overlap/separation) relay ramps and ultimately to underlapping fault segments. Where fault segments underlap, transfer of displacement between them is accommodated by a connecting monocline. When displacement increases and a through-going fault forms, relay ramps are preserved as fault-bounded zones of elevated bed dip and monoclines are preserved as areas of normal drag. Therefore, the orientation and magnitude of bed dips within and adjacent to a fault zone, and the numbers of segments seen on a cross-section through it, depend largely on the aspect ratios of relay ramps in the initial fault array. The aspect ratio of relay ramps varies between different fault systems. An analysis of the geometry of 512 relay ramps from 13 different fault systems suggests that the main controls on aspect ratio are the strength of the sequence at the time of faulting and the underlying structure.
