Fracture” project: Promoting the recognition and chemical analysis of wear marks

The Fracture project, developed by R. Gosselin, a research engineer and microwear specialist in the Trajectoires laboratory, aims to improve the interpretation of wear marks by focusing on spectroscopy data.It has led to the filing of a patent for a new spectroscopy imaging system. A prototype tool built around this patent, the microspectro-imager, is currently being developed in partnership with Acmel Industries.

The use of the microspectro-imager revolves around five main steps:

  1. Identification of micro-traces of use
  2. Capture of the corresponding spectrum
  3. Transforming the spectrum into a data curve
  4. Analysis of the spectrum with dedicated software
  5. Interpretation

The microspectro-imager was presented at the eNova exhibition in Paris in 2018

Chalcolithic lithic industries of Sultana My research focuses on the lithic industries of the Chalcolithic sites of Sultana, thanks to new excavations led by C. Lăzăr, and includes training a Romanian student in lithic technology. Autour du grand tell daté du Gumelnița et fouillé en 1924 (Andrieșescu 1924), se trouvent des sites plats et des cimetières couvrant l’ensemble du Chalcolithique : Boian pour l’étape ancienne et Gumelnița pour l’étape récente. Les sites sont installés dans la grande plaine loessique roumaine, sur la rive droite du Moștistea, affluent du Danube, et aujourd’hui au bord du lac artificiel de Moștistea. Contribution to the monograph on the Varna Necropolis Three bilingual (German, English) volumes dedicated to the necropolis of Varna, Das Varna Gräberfeld, will be published by Philipp von Zabern, in the DAI Eurasian Series, edited by V. Slavčev. I am in charge of the lithics, which I comprehensively reviewed after the recent revision of the funerary inventories. The multidisciplinary approach will combine technological and typological data, in connection with raw material supplies and types of production, as well as the functional analysis carried out by M. Gurova. L. Manolakakis in V. Slavčev, Dir. (2020, à paraître) IRP NORth (2020-2023) The Eastern European model of Neolithization contrasts with that of the West, in terms of modes and chronology. In the central Russian plain, the beginning of the Neolithic is dated between the second half of the 7th and 6th millennia BC, depending on the region considered, and is defined by the emergence of sedentarism and the appearance of ceramic technology. Despite occasional contacts with mixed farming groups, local populations maintained a lifestyle based on hunting, fishing and gathering. It was not until several millennia later that a real production economy was adopted and became widespread in the area (3rd and 2nd millennia BC). Based on the duration and the breakdown of events recorded in the Russian plain, we can follow the history of communities in the process of Neolithization in a very original way.
