Geochemical characteristics and contemporary metallogenetic process of hot springs in tengchong

摘要

The characteristic element abundance value/concentration coefficients of the geochemical characteristics of Tengchong are: Au-6.10/4.07, As-7.13/3.96; Sb-1.25/6.23; Pb-30.87/2.47; Th-20.25/2.11; Cd-0.57/2.83; Li-40/2; Ti-1.30/2.89 (abundance unit; Au - 1x10~(-9), the others - 1x10~(-6)). Generally, these 8 elements can reflect the characteristics of the metallogenetic process with magmatic hydrothermal activities in the area. The abundances of other 32 elements measured are similar to those of the crust.
