西湖凹陷古近系矿层的地质背景及成矿特征

Geological background and metallogenic characteristics of Paleogene ore beds in Xihu Depression

西湖凹陷是东海陆架盆地的重要勘探区域,古近系是研究区重要的地层,也是烃源岩主要的发育层位。西湖凹陷已证实有丰富的矿物储层。本文通过对西湖凹陷古近系矿层的物理性质、化学性质等分析得出,西湖凹陷古近系矿层具有较高的开发潜力,具有多个有利的矿藏勘探领域,是我国能源开采的重点区域,对促进我国经济发展有着重要的意义。

Xihu depression is an important exploration area in the East China Sea shelf basin.Paleogene is an important stratum in the study area,and also the main development horizon of source rock.Xihu depression has been proved to be rich in mineral reservoirs.Based on the analysis of the physical and chemical properties of the Paleogene ore bed in Xihu depression,this paper concludes that the Paleogene ore bed in Xihu depression has high development potential,has many favorable exploration fields,is the key area of energy exploitation in China,and has important significance for promoting the economic development in China.
