can someone tell me about Mt. Pelee volcanic soil and the excuvation because I am doing a report?

Question

tell me about the volcanic soil and the excuvations thanks!

Answer 1

At least some of the volcanic soil of Martinique is classified as a slightly acidic "vertisol"--a soil in which there is a high content of expansive clay known as montmorillonite that forms deep cracks in drier seasons or years. The montmorillonite forms from the weathering of volcanic material.
Alternate shrinking and swelling of a vertisol causes self-mulching, where the soil material consistently mixes itself, causing vertisols to have an extremely deep A horizon and no B horizon. (A soil with no B horizon is called an A/C soil).

I don't know about excavations. I assume you found descriptions of the 1902 eruption and its history--but if not, here's a good one: http://www.geology.sdsu.edu/how_volcanoes_work/Pelee.html

i'm getting large satisfaction in systimatically dealing with all of their questions and solutions, reporting all of them. What works one way, works any different way too.
