文摘
- •
On Titan, destabilization of crustal MCH by cryolavas can release trapped methane.
- •
This methane contributes to Titan's current atmospheric methane level.
- •
However, this process cannot maintain methane resupply over geological time.
- •
The areal scale of this activity may be modest and difficult to detect.
- •
The origin of Titan's atmospheric methane and current resupply mechanism remain a mystery.
