Testing for eustatic sea-level control in the Precambrian sedimentary record

Documenting the sequence record in the Precambrian has proved difficult owing to fragmentary preservation and structural deformation. Methods of dating are at present not precise enough to permit reliable regional correlation or testing of high-frequency sequence-generating mechanisms. Some studies of Precambrian sequence architecture have been achieved, but these indicate tectonic processes acting at a much slower rate than during the Phanerozoic. Further analysis of this problem is required.
