【 摘 要 】

This study reports the occurrence and petrologic significance of Ti-clinohumite for the first time in the Ciénaga skarn, Sierra Nevada de Santa Marta Massif. Ti-Clinohumite occurs as thin bands hosted in the Ciénaga Marbles of lower Cretaceous age, which consist of quartz-wollastonite-diopside-garnet-clinohumite marbles. We focus the attention on the occurrence of Ti-clinohumite-bearing domains, highlighting some interesting textures as well as the mineralogy and chemistry of the Ti-clinohumite. On the basis of its geologic situation, petrography, mineral composition and metamorphic history, we discuss the origin of Ti-clinohumite.
