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
