There is a gash in the earth's crust from Iceland to the South Atlantic, chugging out more basaltic crust than any contemporary volcano, and we're not in the middle of a global flood. Similarity of minerals, rock types, tectonic features, and all other aspects of rocks characterize all the 'geologic eras'. This vague statement really doesn't say anything, but it's wrong, anyway. Certain features like greenstone belts are not found in all geologic eras. Greenstone belts are characteristic of the Archean and Proterozoic Eons, and Archean greenstone belts contain more ultramafic rock than do Proterozoic greenstones .
Geologists consider banded iron formations to be the first indications of free oxygen in the oceans.
Pyrite and uranitite, minerals formed in the absence of free oxygen, are found in Archean rocks, but another iron-containing mineral, hematite, is not. On a relative scale, mountain building 'episodes' all seem to have occurred 'recently' with few, if any, demonstrable exceptions. They probably represent late Flood topographic adjustments which ended the Flood. With all of the qualifications and vagaries, the first sentence is totally meaningless. Just in case the geologic evidence isn't good enough, the ICR offers the following Biblical evidences.
