摘要

Gulu hot spring is located on the west bank of Sangqu River, Gulu town, Nagqu county of Tibet. The elevation is about 4 700～4 750 m. It is still intensely activing. Consisted mainly by geyserite, the sinter formed a medium scale hot spring type Cs deposit. On the basis of investigating the characteristics of the field geology and study on chronology, this paper systematically studies the characteristics of geology-geochemistry and the ore forming process. The kinds of structure are megagrained massive, brecciform, cataclasis and foliated, fine-grained pore, compact massive and oolitic. The kinds of texture are grained, colloform, organic, corrosion, rectangle, coating and tubular etc. Organic texture exists in all ore-forming stages of Gulu Cs deposit. The main mineral of geyserite is Opal. On the basis of deep geological process, Gulu Cs deposit is formed mainly by organic process.
