A low angle oblique imbrication formed. In the Bivalvia, it refers to a thin, long, concentric imbrication. The type of imbrication is generally related to paleoflow direction. The recent myoconjuctival technique of enucleation is an alternative to muscle imbrication. The bulk of conglomerates deposited in this setting are clast-supported with a strong AB-plane imbrication. Conglomerates deposited in a fluvial environment often have an AB-plane type imbrication. Crude sorting with boulder imbrication can occasionally be seen on the surface of felsenmeers. Vowel imbrication is the vowel harmony-like morphophonological phenomenon found in many Bantu languages. Imbrication is observed in conglomerates and some volcaniclastic deposits. Schmidt noted the heterogeneity and imbrication of the scales, which makes meristics difficult on "Geckolepis". "Imbrication" is an analytic concept that helps to ask questions about historical data.
