Raw material studies of West Central Serbia
Journal of Lithic Studies, 2014 This paper deals with raw material problems in the territory of West Central Serbia geologically determined as the Čačak-Kraljevo (or West Morava) basin. Our research is presented through the most striking case studies, Lojanik, Vlaška Glava and Lazac.

Archaeometry, EarlyView.Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

Unravelling neomorphism: recrystallization pathways in Proterozoic microfossiliferous chert
Frontiers in Earth ScienceEarly diagenetic chert serves as a critical archive of life on Earth, yet the mechanisms of chert formation and diagenesis remain uncertain. The present research deciphers chert formation and recrystallization through petrographic observations of ...

Mineralogical and geochemical characteristics of mudstones in the Jersovec chert deposit
Geologija, 2017 Jersovec chert deposit is a part of the transitional zone between the internal and the external Dinarides. Tethyan cherts are often interlaid with fie-grained material, as is also the case in Jersovec, where chert beds interchange with several thin, up

Archaeometry, EarlyView.Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

The Comminution of Chert Gravel by Microwave Irradiation
ResourcesChert, a by-product rock of sand quarrying, has historically posed economic challenges for aggregate production, resulting in significant “waste” accumulation in quarries.

Transfer cells in Horneophyton lignieri illuminate the origin of vascular tissues in land plants
New Phytologist, EarlyView.Summary Recent fossil discoveries and advances in plant phylogeny have renewed debate about the most recent common ancestor (MRCA) of land plants and the evolution of its fundamental organs and tissues. We re‐investigate the vascular system of Horneophyton lignieri, an exceptionally preserved Rhynie Chert fossil central to understanding early plant ...
