A characteristic of low-temperature ocean floor titanomagnetite oxidation is the formation of irregular, curved cracks, which are caused by shrinkage of the spinel lattice. The spatial distribution of the shrinkage cracks within individual titanomagnetite grains, magnetically extracted from different ocean floor basalts, was studied by Scanning Electron Microscopy. The cracks do not develop in grains smaller than approximately 5 microns in diameter. Under ocean floor conditions the critical titanomagnetite oxidation state z for the onset of cracking is between z = 0.23 and z = 0.37. Shortly before the onset of cracking internal stress reaches a maximum, which if reflected in the magnetic coercivity of the material.
