About this Research Topic
For most of the planet’s history, Earth’s continental environments were fundamentally different from their modern-day counterparts, devoid of any interaction with macroscopic life forms. Sedimentary successions deposited in such environments and further down the source-to-sink profile may thus present a challenge to the uniformitarian approach of explaining ancient strata through modern analogue. Yet potential clues to the behaviour of these systems may be found in studies of depositional settings such as sparsely-vegetated modern desert basins, or hydrodynamic and windblown features preserved on other planetary bodies.
The relatively large number of research studies on pre-vegetation siliciclastic deposits published in the last decades have highlighted a growing interest in the nature of Earth’s depositional dynamics in continental environments devoid of vegetation. Moreover, there has been particular interest on the impact of land plants on sedimentation processes concurrent to their evolution throughout the Palaeozoic, and on the nature of depositional processes responsible for various landforms observed on other planetary bodies, such as Mars and Titan. Additionally, an understanding of depositional settings developed in modern aggradational environments with little to no vegetation can provide fundamental insight into our understanding of preserved sedimentary deposits on early Earth and other planets. We aim to provide a collection of papers concentrated on various topics which can collectively enhance our knowledge about products of deposition that accrued on a planet devoid of land plants, and other lifeforms.
We call for manuscripts that present novel research data, or comprehensive reviews, on pre-vegetation siliciclastic sedimentary deposits, including modern alluvial plains and aeolian settings in sparsely-vegetated environments, deltaic and estuarine systems, shallow and deep-marine environments and flow-related features and aeolian bedforms on other telluric bodies. We encourage the submission of research studies including, but not restricted to, sedimentary geology, sedimentary facies analysis, depositional architecture analysis, geomorphology, sedimentary geochemistry, sedimentary petrography, flume studies, and interplanetary remote sensing.
