Layer
Name
Sublimating Water ice particles 67±31μm containing 1wt% mineral mixture of Magn. 63wt%, Ant. 9wt%, Dol. 6wt%, 0-36µm grains in inter-mixture and NH4-nontr. 22wt% in intra-mixture
Order
1
Type of layer
granular
Texture
loose granular
Type of porosity
particulate
Density
0.5 $\pm$ 0.1 $g.cm^{-3}$
Comments
This is a sublimating layer, so its texture and density are poorly known because they may change during sublimation.
Comments
This layer is made of the remaining icy particles below the sublimation mantle.
