Help with collocations, please

This fine morning I'm working on the e-learning project on studies skills
for
Doctoral students I've been commissioned to develop. I'm writing about how
a
knowledge of collocations is essential to develop academic writing skills,
and
I'm putting together a table of examples. (Collocations are words which
commonly hang out with each other in phrases which form accepted blocks of
meaning. In this context I'm looking especially at collocations with
adjectives
and adverbs).

This is what I've got so far:

adverb + adjective 
abundantly clear

adjective + noun
colossal explosion
substantial reduction
pleasant environment
admirable gesture
sound investment
fantastic op****tunity 
high quality
unmitigated disaster
heavy rain 
deep sleep
strong denial

noun + adjective
proof positive

verb + adverb
rain heavily
sleep deeply
deny strongly

adverb + verb 
richly deserve

Then a moment ago I posted a reply with the words, 'I stand corrected',
which
is verb+adjective and reminiscent of the recent and regular 'why is it "he
looks sad" and not "he looks sadly"?' thread, but please lets not go
there. [1]

Anyway, I'd be very grateful if I could sample auers', aeurs' and melees'
suggestions for further inclusion in the four lists.  The things I've got
so
far are OK, but none of them sound as though they might have come from a
piece
of academic writing, and that's the sort of example I'm after.

If anyone is interested, there's a rock paper about this stuff here:
