I am geologist interested in the ophiolites of Guatemala. Although I may
not be able to join the team to visit the ophiolites in other countries, I
am very interested in joining you on this part of the trip. Please, keep me
informed of further developments of the plan.

I am currently working in western Guatemala (Huehuetenango, Polochic fault)
in a region where some serpentinite occurrences exist. I have also visited
a magnesite deposit in Izabal, as well as the tertiary, coal-bearing
clastics in the Lake Izabal Basin, that were the topic of my M. Sc. thesis.
(Mota, Colorado School of Mines, 1990)

Since I am a Guatemalan resident, I may be able to coordinate any needed
local arrangements.

Regards,

Byron Mota-Vidaurre
