Hi Janos,
This should be useful, though it addresses thermal cracking:

Subject: intragranular versus intergranular microfracturing in rocks
Dear colleagues,
we are studying Mode I fractures in limestone using BIB-SEM and see that the
fracture is partly intracrystalline (nice flat and stepped calcite cleavage)
and partly intercrystalline (broken grain boundaries and pores).
I tried to find papers about intragranular versus intergranular fracture
surfaces and the ratio between intra- and intercrystalline microcracking in
different rocks but was not very successful - may I ask your help in finding
the relevant literature?
Thanks in advance
kind regards, Janos
