Cerberus Fossae是一个陡峭的一组槽,在Elysium Mons以东切割火山平原。 火星上的陡坡有活跃的滑坡(也称为“崩坏作用”),这里我们看到了两种活动的证据。

首先,斜坡上浅蓝色的巨石似乎起源于剖面顶部附近的基岩层(也是浅蓝色)。其次,深色细线是反复出现的坡线,可能也是由于崩坏作用导致,但其由较细粒度的材料组成。

这张照片是由火星勘测轨道飞行器上的HiRISE相机拍摄的。

Cerberus Fossae is a steep-sided set of troughs cutting volcanic plains to the east of Elysium Mons. Steep slopes on Mars have active landslides (also called “mass wasting”), and here we see evidence for two types of activity.

First, the light bluish boulders on the slope appear to originate at a layer of bedrock (also light blue) near the top of the section. Second, the dark thin lines are recurring slope lineae, probably also due to mass wasting, but composed of finer-grained materials.

This image was captured by the HiRISE camera on the Mars Reconnaissance Orbiter.
