The ocean basins are relatively new and have very little organic deposits.
>> The oceanic crusts (which are entirely relatively young basaltic) are only
around 3 miles thick. <<
I agree.
The basins also are similar in age. If you discount the sediments around the
larger rivers you have newly formed crust with very little sedimentary
deposits.
These new basins formed all at the same time and are the result of the crust
being removed by a passing star and the molten layers below cooling into new
crust.
