A new model for the formation of microbial polygons in a coastal sabkha setting [PDF]

, 2017
The stratigraphic record of microbially induced sedimentary structures spans most of the depositional record. Today, microbes continue to generate, bind and modify sediments in a vast range of depositional environments.

SEDucate: sedimentary log exercises for an active learning environment

Sedimentologika, 2023
Active learning in higher education has been shown to improve students’ learning experience by focusing on a student-centered environment. However, the development of realistic activities that simulate the complexity of real world examples while being ...

Sedimentary pyrite sulfur isotopes track the local dynamics of the Peruvian oxygen minimum zone

Nature Communications, 2021
Sulfur cycling is ubiquitous in sedimentary environments, where it mediates organic carbon remineralization, impacting both local and global redox budgets, and leaving an imprint in pyrite sulfur isotope ratios (δ34Spyr).
