Still think there should be heavily volcanic planets.
Aren't most planets that are young more or less lava planets?
My Astronomy and limited geology is a bit dated, but I believe you are correct. However the current theory is that this would be relatively mid-late in the development phase where there are many small bodied objects littering the orbital field, colliding with one another frequently; subsequently heating up the large bodied objects, causing the elements and metals to separate and cores to form where the surface soon cools. (in terms of Billions of years)
