About

Kaarel Mänd is an Earth science PhD candidate at the University of Alberta under the supervision of Dr. Kurt O. Konhauser, Dr. Aivo Lepland, and Dr. Kalle Kirsimäe. He focuses on changes in rock weathering and nutrient cycling that affected Earth's oceans, atmosphere, and biosphere in the Precambrian eons. For this purpose, he utilizes a variety of trace metal-based paleoenvironmental proxies preserved in ancient sedimentary rocks.

Research interests

Paleoproterozoic redox

Redox evolution of the ocean and atmosphere in the middle Paleoproterozoic, especially relating to the Lomagundi-Jatuli and Shunga events.

Trace metal geochemistry

The weathering of trace metals on land, their transport into the marine realm, and partitioning in sediments.

Phosphogenesis

The generation of phosphate-rich minerals and sediments. The preservation of microbes in apatite and their role in its nucleation and growth.

Amber geochemistry

The provenance of amber deposits as revealed through their stable isotope composition and spectral characteristics.
