Facies (Petrology 💎)
In geology, a facies is a body of rock with distinctive characteristics. The characteristics can be any observable attribute of rocks and the changes that may occur in those attributes over a geographic area. A facies encompasses all the characteristics of a rock including its chemical, physical, and biological features that distinguish it from adjacent rock. The term "facies" was i...

New paper!
We usually think of #sediment getting finer as we move away from the shore. But, when biogenic and oceanographic factors come into play in the #mesophotic zone, the patterns could be quite different.
I'm really happy with how this paper came out. It's a very holistic view of how sedimentary #facies are actually distributed, with #seafloor photography, acoustic imaging, sampling, quantitative thin section analysis, and #multivariant statistics.

"HIGHLIGHTS:
• [They] mapped channels and fossae within the volcanic plains east of Olympus Mons.
• Late Amazonian channels east of Olympus Mons formed by eruptions of lava or water.
• Fossae morphologies correspond to episodes of magmatic dike and sill emplacement.
• Loading of Olympus Mons may control magmatic ascent processes and eruption types..."

New #preprint out: How does acoustic #facies mapping match against the facies we can actually recognize in the #sediment? And what actually governs that sediment distribution? We have some insight on both from the shelf of #Malta.

Food for thought #Samples from higher #paleolatitudes were on average smaller, but contained #outliers with the largest #sizes, highlighting the need to analyze entire #distributions. #Lithology and #collection differences need to be accounted for when evaluating #size differences across #space (#polar #gigantism) and #time (#Lilliput #effect). Similarly, differences in #facies may affect #species #determination

Body-size distributions of organisms across #environments in space and time are a powerful source of information on #ecological and #evolutionary processes. However, most studies only focus on selected parameters of #size distributions (e.g., central tendency or extremes) and rarely take into account entire #distributions and how they are affected by the #collection style and #facies
