11. There are many controversies about CAOB tectono-magmatic evolution. 12. Some of the magmatic differentiation may have occurred in closed magma chambers. 13. This magmatic inactivity occurs because the flat slab removes the asthenospheric wedge. 14. Water appears to be in part magmatic and in part precipitation-derived. 15. These igneous rocks were once part of a proto-Andean magmatic belt. 16. The magmatic axis of the arc is well defined from Honshk to Guam. 17. Magmatic activity and rifting may also be independent events.18. Proximity to large igneous provinces may also be helpful in identifying magmatic underplating. 19. Later eruptions from El Jorullo were magmatic with neither mud nor water flows. 20. This igneous intrusion is part of the larger Cortlandt-Beemerville magmatic belt.
