Study of skeletal residues degradation using infrared spektroskoscopy

Infrared spectroscopy is one of the most frequent method used for identi'cation of various materials. Method was used in this study for characterisation of postmortal degradation of skeletal residues. An Essentials importance for preservation or degradation of bone tissue have the qualities of surrounding soil – mainly pH level and humidity. In acidic surroundings the mineral composition of bone – hydroxyapatite Ca5(PO4)3OH is gradually melt, which can 'nally eventuate in decalci'cation of bone tissue. Another result of the acidic environment is recrystalization of hydroxyapatite into the other mineral called bruslit (CaHPO4 . 2 H2O). Brushit occurence was approved in bones of Dietrichstein family members, who were buried in a family crypt in Mikulov. A speci'c factor in.uencing degradation of bones is high temperature. FTIR spectroscopy can be used to dif- ferentiate between burnt or unburnt bones and thanks to this method the temperature of cremation and the burning conditions can be successfully estimated. Bone residues coming from the necropolis in Přibor (the Bronz Age, the Iron Age) and also animal residues from Chotěbuz-Podo- bora were analysed.

New archaeological pieces of knowledge from a hillsite of the Púchov culture at the Okrouhlá hill (the village of Staříč near Frýdek-Místek)
 Stabrava, Pavel
The paper brings a story of archaeological recognition of the Púchov culture hillsite at the Okrouhlá hill and the new pieces of knowledge obtained in the course of archaeological rescue excavation in 2001. The excavation was connected with construction of a sender for the mobile telecommunication net Paegas. The fortified place had an area about 0,5 ha. Inside the fortification there was found a posthole construction, probably of big dimmensions. All archaeological finds give evidence rather for a fortified farmstead or a refuge than for a stronghold.
