The earthquake of M W 5.6 on 22 May 2012 in SW Bulgaria is a shallow normal-faulting earthquake. Coseismic ground cracks along a fault-line scarp, focal mechanisms and hypocentre allocations suppose that the seismogenic source is a normal fault segment from the NW boundary fault of Pernik basin, named Meshtitsa fault, which has not been considered...

Context 1
... deposits in the trench are divided into Holocene deposits of units A, B, and C; and basement units D, E, and F (Fig. 2). Unit A is a plough zone. Unit B is dark, massive, with prismatic partition, built of clayey-sandy material with rare angular and semi-rounded pebbles and sandy lenses, rare calcite enrichments, and a lot of ceramics and charcoal in the base. The age of ceramic fragments is Late Bronze (1200-800 BC). Unit C is built of clayey-sandy ...
Context 2
... distinct faults are recognized (Fig. 2). The front fault separates units D and E. The basement units and the fault are eroded by a Holocene alluvial channel of unit C. The base of Holocene channels is not affected by fault displacement. The rear fault is positioned between Paleogene conglomerate (unit D) and Upper Cretaceous agglomerate tuff (unit F), and offsets the ...

Cretaceous and Paleogene sedimentary sequences of the eastern Caucasus show the traces of vertical migration of gel-type diagenetic products (silica, iron sulfides). Signs of the migration of SiO2 compounds were recorded in the carbonate rocks with an admixture of biogenic silica; the traces of sulfide migration are confined to the alternation of l...
