| A Discussion on the Metallogenic Model of the Leqingla Iron-Lead-Zinc Deposit, Tibet |
| This paper studies geological background, geological features, ore-controlling factors of mineralization and metallogenic model of the Leqingla iron-lead-zinc deposit. The deposit is located in the north ore belt of eastern Gangdise island arc orogenic belt, the iron-lead-zinc ore body is in layered form, and it is strictly controlled by the carbonate rocks and interlaminar fracture zone; the mineralization is closely related to the contact metasomatism of Jubuzari collision granodiorite (45 Ma); the copper-lead-zinc ore body is in veined form with the normal fault fracture zone, and the mineralization is related to the magmatic hydrothermal filling resulting from late collision of dioritic porphyrite (38.8Ma); It is concluded that the depth of the Leqingla mine has the potential in search for copper polymetallic ore bodies, and the importance should be attached to mineralization of late collision granite at the north ore belt along the eastern section of the Gangdise metallogenic belt. |
