The team's performance is divided into two main formation-flying demonstrations: all six airplanes flying in a tight delta (triangle) formation, alternating with maneuvers in which four of the airplanes fly in a diamond formation while the remaining two airplanes perform various solo stunts.
Our previous research indicated that void-based elongation (Fig. 6a, mechanism I) and wrinkle-based elongation (Fig. 6b, mechanism II) were the two main formation mechanisms of grooved texture [22, 24].
These can become great substitutes for the locals wherever the three main formations are absent.
The volcanostratigraphy is divided into six main formations — Risco, Ajuda, Bretanha, Lombas, Santa Bárbara and Lagoas, each defined by different activity phases in the volcano's evolution.

Two main geological formations, the Gercus formation and the Midyat formation, form the geological structure of the study area.
The area forms part of a geological sequence of the Quaternary and Tertiary formations of the Niger Delta, consisting mainly of three main geologic formations: The Benin Formation, Agbada Formation, and Akata Formation (Sundararaman et al. 2002).
Asmari and Sarvak limestone are two main oil producer formations in Iran and the Middle East.
