| 摘 要： | 豫北粘土矿集中分布于沁阳-焦作一带,在东段因受断层破坏,矿层呈长条状分布;西段受沟谷切割,矿层在山顶成为孤立的残留体。矿体形态、产状主要取决于基底碳酸盐古岩溶地形。根据岩相地理环境的差异和矿床特征,豫北地区由南到北划分为两个矿石-岩石相带,根据岩石组合,沉积构造、生物化石、微量元素等特征,将区内中石炭的沉积由北至南依次划分为滨-浅海相、滨海相两个相区,以此探讨该区粘土矿的成因。

| Abstract: | Clay deposits in north Henan are distributed over the Qinyang-Jiaozuo belt.In the eastern section,ore bed occurs in stripped form,while in the western section,ore occurs isolated blocks.Shape and occurrence of the orebodies are controlled by paleokarst landform of the carbonate basement.The clay deposits in north Henan may be divided into 2 sedimentary facies belts according to sedimentary facies and into 2 facies areas such as littoral-neritic facies area and littoral area according to rock association,sedimentary structure,fossils and microelement geochemistry from north to south. |
