Abstract
The geological structure of Baoxingchang orefield is complicated and the metallogenetic condition is advantageous.The northeastward Xiangshui fault zone in this area is the main rock-control and ore-control structure.There are 3 types of Au deposit,which are formed separately in the porphyry metallogenetic period,hydrothermal metallogenetic period,epigenetic metallogenetic period and have their corresponding metalloge-netic models.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
