Based on displacements along two monogenetic volcanoes, slip rates of have been estimated. Some sources make a distinction between two forms of monogenetic diabetes&colon; MODY and neonatal diabetes. Finally, they are also common as parasitic and monogenetic cones on complex shield and stratovolcanoes. Monogenetic cones usually erupt in the Strombolian style. Other monogenetic volcanoes are tuff rings or maars. The field covers and consists of 25 monogenetic volcanoes and about 15 further vents. Many small monogenetic volcanoes formed around the uplifted block. Monogenetic eruptions can last for more than 10 years. See monogenetic theory of pidgins for more information. This could explain why creole languages have much in common, while avoiding a monogenetic model. They may occur as a monogenetic volcanic field or a polygenetic volcanic field. Subglacial volcanoes that are monogenetic are far more narrow, steeper, flat topped structures. A monogenetic field typically contains between ten and a hundred volcanoes. In addition, large calderas and monogenetic volcanoes exist in the Andes. The volcano is most likely a monogenetic volcano, meaning that it only erupted once.
