The Temburong Formation tuff is a thin, single bed, suggesting it is either the distal portion of larger tuff unit, or that it is the product of a relatively small, locally sourced, single eruption. The absence of thick and widespread, tuff-dominated, volcaniclastic material argues strongly against the presence of major caldera-forming eruptions.
