Metallogenic Dynamics Background of Ga’erqiong Cu-Au Deposit in Tibet, China

The Ga’erqiong Cu-Au deposit, which sits on the north side of the Coqên-Xainzamagmatite belt, is a large-scale skarn-type deposit, whose ore body has formed in the skarn zone in the contact part of quartz diorite and marble of Duoai formation or the cracks of quartz diorite. Its mineralization is cl...

description	The Ga’erqiong Cu-Au deposit, which sits on the north side of the Coqên-Xainzamagmatite belt, is a large-scale skarn-type deposit, whose ore body has formed in the skarn zone in the contact part of quartz diorite and marble of Duoai formation or the cracks of quartz diorite. Its mineralization is closely related to quartz diorite. And granite porphyry-related molybdenum ore still exists in its deep part. Currently, there are disputes about the metallogenic dynamics background of this deposit. From previous studies, this paper carried out zircon LA-LCPMS U-Pb dating and petrogeochemistry study for quartz diorite of Ga’erqiong Cu-Au deposit. The testing result indicates: quartz diorite and granite porphyry were formed respectively in 88±2Ma and 83±1Ma, belonging to the magmatic activity of the early stage of Upper Cretaceous; quartz diorite and granite porphyry have geochemical characteristics similar to those of island arc rock of subduction zone and geochemical indexes similar to “adakite.” Combining with the regional tectonic evolution, we think that quartz diorite and granite porphyry were all formed in the extension environment after the collision of Lhasa block and Qiangtang block. Quartz diorite is the result of the migmatization of basic melt and acid melt evoked by asthenosphere material raise caused by lower crustal delamination; the formation of granite porphyry may be crust-mantle material’s partial melting results due to delaminated lower crustal. Therefore, Ga’erqiongskarn-type Cu-Au deposit belongs to the metallogenic response to the collisional orogeny in the closing process of Meso-Tethys.

Su mineralización está cercanamente relacionada a los cuarzos de diorita. La mena de molidbeno granítico relacionada a los pórfidos tiene presencia en estas zonas profundas. Actualmente, se presentan varias discusiones sobre el origen de las dinámicas metalogénicas de este yacimiento. Con base en trabajos previos, este estudio determinó la edad del circón uranio-plomo con la técnica LA-ICPMS y analizó la petrogeoquímica de cuarzos de diorita para el yacimiento Ga'erqiong. Los resultados del análisis indican que los cuarzos de diorita y los graníticos pórfidos se formaron en 88±2Ma y 83±1Ma, respectivamente, y pertenecen a la actividad magmática de la edad temprana del Cretácico Superior; los cuarzos de diorita y los graníticos pórfidos tienen características geoquímicas similares a aquellas de las rocas del arco insular en la zona de subducción e índice geoquímicos similares a la "adakita". En combinación con la evolución de la tectónica regional, se concluye que los cuarzos de diorita y los graníticos pórfidos se formaron en el ambiente extensivo tras la colisión de los bloques Lhasa y Qiantang. Los cuarzos de diorita son el resultado de la migmatización de fundición básica y fundición ácida suscitada por el material elevado a la astenosfera gracias a un deslaminado menor de la corteza; la formación de los graníticos pórfidos podría ser el resultado de la fundición parcial de material en el manto de la corteza debido a un deslaminado menor en la corteza. Además, el depósito Ga'erqiong corresponde a la respuesta metalogénica de la orogénesis colisional en el proceso de cierre del Mesotetis.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geocienciahttps://revistas.unal.edu.co/index.php/esrj/article/view/65192Universidad Nacional de Colombia Revistas electrónicas UN Earth Sciences Research JournalEarth Sciences Research JournalOuyang, Yuan and Yang, Wunian and Huang, Hanxiao and Liu, Hong and Zhang, Jianlong and Zhang, Jianhua (2017) Metallogenic Dynamics Background of Ga’erqiong Cu-Au Deposit in Tibet, China.
