Mr. Berry’s wide expe­ri­ence of dif­fer­ent types of geo­log­i­cal prob­lems in a wide vari­ety of geo­log­i­cal ter­rains makes him an excel­lent prob­lem solver when issues of geo­log­i­cal inter­pre­ta­tion arise. In addi­tion, Mr. Berry has life­long expe­ri­ence in the inte­gra­tion of diverse data sets to pro­vide answers to geo­log­i­cal ques­tions: these data sets include soil geo­chem­i­cal sur­veys, aero­mag­netic and aer­ial radio­met­ric sur­veys, grav­ity data, and min­eral deposit dis­tri­b­u­tion. An unusual exam­ple of the lat­ter would be the stratabound dis­tri­b­u­tion of emer­ald deposits in the Colom­bian Andes: the deposits define an evap­or­itic hori­zon which has acted in places as a decolle­ment surface.

In addi­tion to explo­ration for cop­per, gold, ura­nium, oil and gas, the range of geo­log­i­cal prob­lems Mr. Berry has been called on to solve ranges from esti­mates of phos­phate resources for a Federal/State land swap in Idaho to esti­mates of chem­i­cal weath­er­ing rates and over­all denuda­tion rates in N. Car­olina, and from map­ping land­slide haz­ards to delin­eation of lime­stone reserves.
