Abstract:

Igneous rocks are very important to study the regional geological setting and the origin of the metal ore deposits. The
magmatic activities were very strong in South Tibet in response to the collision of India plate and the Eurasia continent. However, there
is limited report on igneous rocks emplaced in the Tethys-Himalaya antimony-gold metallogenic belt, especially in its eastern part,
which was near the MCT. Previous studies indicate that the origin of these deposits was related to the magmas. The integrated
exploration area of zhaxikang lead-zinc deposit is located in the eastern part of the metallogenic belt. Recently, we have found
considerable bimodal plutons or dykes in this area. This result is beneficial to study the magmatic activities and tectonic evolution as
well as the origin of related ore deposits. In addition, it provides basic data for investigating metallogenic models as well as ore
prospecting models in North Himalaya.

Key words: igneous rocks, bimodal, Zhaxikang, Tethys-Himalaya
