# In situ microseismicity reveals lithospheric accretion at the ultraslow-spreading Gakkel Ridge, Arctic Ocean

## TL;DR

New seismic data from the Arctic Ocean's Gakkel Ridge show a deep fault linked to how the Earth's lithosphere grows in this area.

## Contribution

The study identifies a deep-seated fault at the Gakkel Ridge connected to an incipient detachment fault.

## Key findings

- A deep-seated fault was identified at the Gakkel Ridge using microseismic data.
- The fault is likely linked to an incipient detachment fault.
- This finding helps explain the ridge's segmentation and lithospheric accretion processes.

## Abstract

New on-site microseismic data reveal a deep-seated fault at the Gakkel Ridge in the Arctic Ocean, which is likely linked to an incipient detachment fault that controls the ridge’s segmentation.
