Sedimentary and faunal evidence for the Late Devonian Kellwasser and Annulata events in the Balkan Terrane (Bulgaria)

open access: yesGeologica Balcanica, 2015
The global Upper Kellwasser (Frasnian–Famennian boundary interval) and Annulata Events (base of upper Famennian, Upper Devonian IV-A) are recorded for the first time in deep marine sedimentary successions of western Bulgaria. Within the upper Parchar Formation of the Lyubash-Golo Bardo Unit, a distinctive black shale unit yielded frequent, partly still

Anomalous Upper Devonian mercury enrichments : comparison of Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) and Atomic Absorption Spectrometry (AAS) analytical data [PDF]

open access: yes, 2018
Mercury geochemistry is emerging recently as a hot topic in chemostratigraphical and facies research, owing to the diagnostic character of Hg enrichments as a proxy of volcanic activity (crucial in the context of assumed causal links between volcanic ...
