Lithic Management in the Chassey Culture Neolithic [PDF]

open access: yes, 2009
The integrated technological approach of the lithic industries in Southern France Chassey culture and neighbouring cultures is a way to highlight a complex organisation of space. The development of long distance diffusion networks of lithic products from

Static recrystallization of shocked calcite in Ries impact breccias

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia

Araguainha Dome, Brazil: A polygonal impact structure due to a complex pre‐impact regional structural framework

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

BRINGING BACK FAMILIAR FORMS: RECYCLING QUINA SCRAPERS AT THE LATE LOWER PALAEOLITHIC QESEM CAVE, ISRAEL

open access: yesOxford Journal of Archaeology, EarlyView.
Summary This study presents a technological analysis of 18 old patinated scrapers and spalls, mostly of Quina technology, that were recycled into new scrapers of the same type at the Late Lower Palaeolithic site of Qesem Cave, Israel (420–200 kyr). Recycling scrapers into the same Quina and demi‐Quina types offers a rare, controlled opportunity to ...

Refrain from Standards? French, Cavemen and Computers. A (short) Story of Multidimensional Analysis in French Prehistoric Archaeology [PDF]

open access: yes, 2015
Focusing on the history of prehistoric archaeology in the 20th century, this papers shows (1) that statistical multidimensional analyses were carried out by a new kind of actors who challenged the previous common language shared by prehistorians.

The first Neanderthal remains from an open-air Middle Palaeolithic site in the Levant [PDF]

open access: yes, 2017
The late Middle Palaeolithic (MP) settlement patterns in the Levant included the repeated use of caves and open landscape sites. The fossil record shows that two types of hominins occupied the region during this period - Neandertals and Homo sapiens ...

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.
