Microtextural Inheritance on Quartz Sand Grains from Pleistocene Periglacial Environments of the Mazovian Lowland, Central Poland
Sand grains from Quaternary glacial, aeolian and fluvial deposits in the Mazovian Lowland, central Poland, were examined to characterize the effects of different Quaternary processes on sand‐grain surfaces that experienced repeated cycles of intense polar‐desert‐like conditions during the Middle and...

Sand grains from Quaternary glacial, aeolian and fluvial deposits in the Mazovian Lowland, central Poland, were examined to characterize the effects of different Quaternary processes on sand‐grain surfaces that experienced repeated cycles of intense polar‐desert‐like conditions during the Middle and Late Pleistocene.
