From June 24th to June 28th, 2019, Associate Professor Liu Xiangchong and Assistant Research Fellow Xiao Changhao of the Institute of Geomechanics of the China Geological Survey of the Ministry of Natural Resources went to Atherton Township, Queensland, Australia to attend the annual meeting of tin-tungsten key metals and magma systems. And make an oral report at the annual meeting. The theme of the annual meeting is the genetic mechanism of the key metal deposits such as tin, tungsten and rare earth, the prospecting mark and its relationship with the magma system. About 70 people participated in the annual meeting, mainly from Australia, China, Germany, Canada and other countries producing tin and tungsten key metals.
Australia's annual meeting of tin-tungsten key metals and magma systems is a very rare international conference on tin-tungsten deposits. The conference brought together many top international experts and scholars in the academic field of tin and tungsten deposits. During the meeting, Associate Professor Liu Xiangchong reported on the research results of the use of multi-component thermodynamic model to simulate the precipitation of hematite in CO2 escape, and discussed the migration and precipitation mechanism of tungsten with the experts. Dr. Xiao Changhao introduced the latest achievements in the investigation of the ore field structure of the typical gold-polymetallic ore concentration area in the eastern part of the geological survey project, and discussed the dating method of the cassiterite mineral dating method with the experts.
The conference organizer also organized an investigation of the superficial Yunyingyan type ore body in the tin-tungsten ore field and visited the Heberton Tin-Tungsten Mine Museum. The Heberton Tin Tungsten Mine Museum records the history of the Hebron tin-tungsten field in the 20th century and retains specimens of the ore and typical ore of hydrothermal deposits in other parts of Queensland.
Through this academic exchange, the Institute of Geomechanics demonstrated the latest achievements in the investigation and research of tin mines, listened to the opinions and suggestions of international counterparts, and learned about the geochemical and tungsten mineralization of granites related to tin and tungsten deposits in the world. The latest research progress in molecular dynamics simulation, geotectonics, magmatic hydrothermal transition and other research directions has opened up the research ideas of tin and tungsten mineralization models and simulations, and has important guidance and reference for future research and research work.
