Question

Quizplus · Accepted Answer

Large igneous provinces are formed by flood basalts, which are massive outpourings of lava that can cover thousands of square kilometers and flow tens to hundreds of kilometers. Sills are flat-lying intrusions and not associated with large igneous provinces. Super plumes are theoretical concepts of mantle convection and not necessarily linked to flood basalts. Highly explosive eruptions, such as those that form calderas, produce relatively small volumes of igneous material compared to flood basalts.
