Spatter deposits are common in basaltic eruptions and serve as a marker for emplacement conditions that other volcanic deposits cannot capture due to either high emplacement rates (lava) or rapid cooling rates (scoria). This cooling rate has been confirmed by measurements taken in drillholes bored into the lava after the water cooling ended [Valdimar Kr. Diorite. Many of them have not yet been investigated, although few have been used as binders for a very long time. — They cooled at different rates.
