[GRASS-user] Vector map area statistics

Dear Grass users,
I have a simple problem for which there is probably a trivial solution or even
a dedicated Grass function by I haven't been able to find it yet.
I am working in area for which I have a vector map of the bedrock geology and
another vector map with a larger number of small basins. For each of these
basins I would like to know the area (or percentage of the total basin area)
that is occupied by the different geological units, and directly upload this
result in the attribute table of the basins vector map (one column for each
geological unit giving its area inside the basin or percentage).
Is there a simple way to do that with Grass?
Thanks in advance,
