Question
Volcanoes are generally not preserved in the geologic rock record because the upper part of the volcano is eroded away. However, the igneous rocks associated with volcanoes are often found preserved in the rock record as layers of volcanic rock and associated intrusions. How could you infer what type of volcano erupted in a given area based on the type of volcanic deposits? Give specific examples and briefly discuss if some materials may be linked to different types of volcanoes.Answer
