WebIn case of thin and irregular lava flows, gas cavities are formed on the rock surface. The rock is called “vesicular” basalt when the gas cavities are empty. The majority of the gas cavities are filled up by secondary minerals (zeolites, calcite, quartz, or chalcedony) and amygdales are formed. Scoria forms when magma containing abundant dissolved gas flows from a volcano or is blown out during an eruption. As the molten rock emerges from the Earth, the pressure upon it is reduced and the dissolved gas starts to escape in the form of bubbles.
