What is this black stuff?

We have a leek in a 1987 Catalina 27'. We started grinding and this picture shows an area at the very top of the keel on the starboard side about in the middle of the boat. This boat has a glass skeg keel of about 12 with the lead keel affixed to the bottom of that. The lead glass joint looks good. This picture is taken from the center of the glass skeg on the starboard side about in the middle. From the bottom looking up the picture clearly shows:
1. Red bottom paint
2. Gel coat,
3. Large Dark green band (very hard)
4. Small White band (Caulk like but rather soft)
5. Large Black band (Like putty very, very soft)
6. Tan, Pink (Very Hard)
It looks to me like #6 is good glass.
What is #5 it is worthless?
What is #4 it is not much better?
What is the #3 layer
The two layers of softer material white and black (about 1/8) is between the solid dark green layer and the tan pink layer #6 from the shaft log to as far as we have ground, which is now mid keel.
Also about half of the #6 layer is spider cracked and crumbling and we ground through the hull.
This boat was grounded before by the previous owner and repaired by the yard in an area of about 6 by 24 primarily with bondo directly behind the keel.
I can't seem to upload a picture.

if your using the "attached files box, make sure it's within spec's listed in the upload window. If it is within spec's, and the window goes blank or just sits dead for more then 30 seconds, close the window and try again. Sometimes it takes 3-4 tries. Try a different slot, sometimes that works too!
