Köppen climate type:
Minerals found in cavities in what is considered as petrified branches from an ancient forest destroyed by a volcanic eruption.
"Neogene tuff beds on the lower slope of Mount Elgon, .... preserve a diverse array of fossil wood ... The age is probably Lower Miocene ... In some specimens, wood has been replaced by natrolite (a sodium zeolite) and calcite. Zeolites, particularly natrolite, are abundant in Mt. Elgon volcanic flows and agglomerates, evidence of magma that contained high water content. Calcite commonly occurs in association with the natrolite, the carbonate mineral having formed both as a primary mineral and as a weathering
product ... The zeolite-rich wood has not been studied in detail, but fossilization commonly results from mineralization of outer-most tissues, with slender natrolite crystals radiating into interior spaces ... In other specimens, wood is completely replaced by interlocking crystals
of stilbite and calcite .
