Structural-magmatic-metallogenic Framework of the Tongshi Gold Ore Field,Western Shandong Province:Insights from Integrated Geophysical Exploration
摘要
Abstract
The Tongshi gold field is a representative gold-producing area in western Shandong Province.Over ten gold deposits have been discovered in the area,including the Guilaizhuang and Zuojiazhuang deposit.The types of gold mineralization in this area are diverse and are obviously affected by tectonic and magmatic activities.Understanding the regional tectonic framework and magmatic evolution process holds great significance for prospecting and prediction in this region.In this study,based on comprehensive geophysical exploration of deep reflection 2D seismic datd,gravity and magnetotelluric soundings in the Tongshi gold field area,the characteristics of geological bodies such as Moho plane,detachment structure zone,magma chamber and magma channel were identified,and the deep structure and metallogenic tectonic background of Mesozoic metallogenic system were roughly identified,which broke through the understanding that Guilaizhuang gold ore body in the region was controlled by a single structure.The tectonic magmatic metallogenic framework was established while perfecting the"one body with multiple types"metallogenic modle.These findings provide a foundation for a new phase of deep gold prospecting prediction as well as related research endeavors.关键词
