河北省平原区矿床纵向分带特征分析

Characteristics of vertical zoning of ore deposits in plain area of Hebei Province

河北省平原区矿产资源丰富,是这一带矿山资源开采的主要集中区。矿区内矿产分布广泛,通过野外地质调查,采集了大量矿物样品进行鉴定研究,根据其矿体内部到外部进行特征分析。但是不同层位的矿产因受沉积环境、封闭条件等因素的影响,其矿化度、r Na/r Cl比值等在纵向上都具有明显的分带特征。

The plain area of Hebei province is rich in mineral resources, and it is the main concentration area of mining resources in this area. Mineral resources are widely distributed in the mining area, and a large number of mineral samples have been collected and identified by field geological survey, and their characteristics are analyzed from the inside to outside of the orebodies. However, because of the influence of sedimentary environment and sealing conditions, the mineralization and rNa/rC1 ratio of the deposits in different horizons have obvious zonation characteristics in the vertical direction.
