Greenland Could Have Records of 3.7-billion-year-old Geomagnetic Fields
Scientists argue that paleomagnetic field tests preserve a geomagnetic field record acquired as chemical remnant magnetization in banded iron formations in southwest Greenland.

New Mechanism for “Giant” Greigite Growth in Deep-Sea Sediments
Understanding greigite formation pathways in sediments is a prerequisite for assessing the marine iron-sulfur-carbon cycle and yield reliable near-syn-sedimentary paleomagnetic records.

Volcanic Creation and Destruction of Temporary Tephra Storage
Pyroclastic density currents (PDCs) are a major threat during an explosive volcanic eruption. A new study shows that loose tephra accumulations on volcanic slopes tend to re-mobilize rapidly.
