Sub-volcanic magma chambers might be a widespread component of flood basalt provinces, and their presence can be revealed in some cases by plagioclase megacrystic basalts. In at least four levels within the Deccan flood basalt sequence the generally low abundance of small plagioclase crystals increa...
