occurred. In some stratovolcanoes such as Taranaki, even the cyclicity of such volcano collapses and their sedimentary responses have been recognized [15]. Individual volcanic particles preserved in ancient rock units carry vital information about the style and type of volcanic eruptions that created those particles, while sedimentary features and the overall facies characteristics can provide information on the transportation and deposition of those individual particles. In arc settings, especially under temperate to tropical, humid climates complex sedimentary environments can form where the volcanism and the background sedimentation together can create complex volcano-influenced sedimentary aprons.
