Stage 2

Unlike the first stage of development, the second stage shows evidence of more explosive volcanism. There are thick deposits of pumice falls, pumice and scoria flows, and block-and-ash flows. Some of the deposits have been classified as nuee ardente (glowing cloud) deposits. Based on lithology, grain size, and sedimentary structures these deposits have been divided into a Pelean type and a St. Vincent type. Pelean types are often generated in association with the growth of domes, such as the activity in 1902-1904. The second stage of activity produced the most silica-rich magma that has been erupted from Mont Pelee.
