Krzemionkowe formy z Egiptu
(2014) Pawlikowski, Maciej ; Sęk, Mateusz Przemysław
Badane organiczne formy zostały odkryte w rejonie Wzgórz Tebańskich w bezpośrednim sąsiedztwie miejscowości Qurna (Górny Egipt). Wychodnie z tymi formami znajdującej się na zachód od Luksoru na zachodnim brzegu Nilu. Omawiane formy poddano badaniom mineralogiczno-petrograficznym.
Mineralogia i struktura wybranych surowców jako czynnik ich jakości
(2014) Pawlikowski, Maciej ; Wróbel, Marta
Paper present results of mineralogical examination of various genetic types of flints and obsidian were performed using polarizing light microscopy, SEM and EDX methods were performed during last 30 years. Various method were used for determining possible relations between internal structures of these raw materials and relations to the best directions for processing. Analyses showed that the best directions for preparation of flint implements are parallel to directions of optical orientation of micro crystalline quartz present in flint. This orientation was the result of the recrystallization process of silica from opal to chalcedony and quartz. The type of processes known as ageing of silica active and observed in flint nodules have persisted for a million years. The growth of microcrystals in primary opal of flints goes a specially well perpendicularly to the direction of stress, i.e., perpendicular to the thickening of rock layers (mostly limestones). Performed investigation confirmed the primary flint nodules formed in situ from sponga organisms show regular nodule shapes. Secondary flints formed due to migration of dissolved silica in deposited sediment had mostly irregular shape. Secondary crystals of quartz present in these flints do not show space orientation and because of this the secondary flints are bad for knapping.
Flint and fire
(2014) Pawlikowski, Maciej
Various knapping techniques of flints used at Stone Age effected production of various implements but was reason of discovery of lightning striking i.e. creation of way kindle of fire. An article presents results of investigation of flints and relations: age of flints, crystallinity of flints – piezoelectricity, age of flints-piezoelectricity.
Dark minute nodules in andesite from the Fintice quarries (Eastern Slovakia), its character and possible origin
(2014) Košuth, Marian; Pawlikowski, Maciej ; Bożęcki, Piotr
Crystals of pyroxene, plagioclase and ilmenite, present at andesite from Fintice, Eastern Slovakia – were examined using the traditional chemical analysis, polarizing light microscopy, scanning electron microscopy with EDS detect or and Raman spectroscopy. Special attention was paid to geochemical determination of rock forming phases crystal growth and to stages of its crystallization. Obtained data were used for reconstruction of these phases crystallization i.e. phases of alternation because of magma chemistry.
Research of flint patina from the Eastern Desert of Egypt
(2014) Pawlikowski, Maciej ; Sęk, Mateusz Przemysław; Sitarz, Magdalena
The subject of patination of flint has been discussed in many scientific publications. The majority of research concentrates on the applicability of the criterion of patina thickness on determining the age of flint artefacts, as well as for studying the correlation of archaeological profiles. Detailed knowledge of the mechanisms of patination, both in terms of physical and chemical, as well as mineralogical processes, is necessary for the correct interpretation carried out for each archaeological site. The large number of factors affecting patination greatly complicates any analysis of these conditions. This publication presents the research results of desert patina developed on flint artefacts in the conditions of the Eastern Desert of Egypt. Studies indicate mineralogical and chemical variability of patina in different types of flint.
