WebDue to their size, the lunar maria are the most obvious volcanic features on the Moon. These vast basalt plains cover over 15% of the lunar surface, mostly on the Moon's nearside. They are typically circular in outline because they tend to fill the bottoms of very large, very old impact basins. Smaller mare patches also occur in the floors of some … WebThis is the famous "3 types of volcanoes" (shield volcanoes, strato volcanoes, and cinder cones), and it is found in many textbooks from elementary school to college. Why is this 3-types scheme so bad? First, it has no place in it for large caldera complexes (such as Yellowstone), flood basalts, monogenetic fields, or mid-ocean spreading centers.
