Petrographical Analysis of Warthian Fuvioglacial Gravels as a Tool to Trace the Source Area – A Case Study From Central Poland [PDF]

, 2014
The petrographical features of the medium- and coarse-grained gravels (4-10 mm and 20-60 mm, respectively) of weathered and fresh (unweathered) deposits indicate, in combination with so-called indicator and statistical erratics, that two glacial lobes ...

Surface and Subsurface Damage Caused by Bullet Impacts into Sandstone

Geosciences, 2021
The shift of armed conflicts to more urbanised environments has increased the risk to cultural heritage sites. Small arms impacts are ubiquitous in these circumstances, yet the effects and mechanisms of damage caused are not well known.

Signs of the aeolian influence on the formation of coastal-marine sand deposits in the Permian (Republic of Tatarstan, Russia)

Учёные записки Казанского университета: Серия Естественные науки, 2019
Sandy deposits can have a different genesis and form in different sedimentation environments. The example of the tar sands of the Early Permian age of the Republic of Tatarstan (Russia) shows the possibility of their complex and polygenic formation with ...

Stochastic reconstruction of sandstones

, 2000
A simulated annealing algorithm is employed to generate a stochastic model for a Berea and a Fontainebleau sandstone with prescribed two-point probability function, lineal path function, and ``pore size'' distribution function, respectively. We find that

Devonian organogenic buildings of the Urals and adjacent regions of East-Europian Platform and West Siberian

Литосфера, 2015
Several reef-building systems occurred during Cambrian-Devonian on the Urals and adjacent regions of the East-European Platform. The first phase was manifested in the Lower Cambrian within a limited area of the western slope of the Urals.
