摘要
河南省禹州煤下铝矿床位于嵩箕铝土矿成矿亚区,郑庄-黄道铝土矿成矿带上.在总结矿床地质特征的基础上,通过分析成矿物质来源来总结成矿规律,进而探讨成矿作用过程.研究认为成矿物质是由基底的碳酸盐岩与古陆的变质岩2 部分共同提供的,物质来源具有多样性.研究区铝土矿成矿作用受多种因素制约,禹州煤下铝土矿的最终形成经历了同生沉积、埋藏改造和保存-剥蚀3 个阶段.
Abstract
The coal-underlying bauxite deposit in Yuzhou,Henan Province,is located in the Songji bauxite ore-forming sub-region and along the Zhengzhuang-Huangdao bauxite ore-forming belt.Based on the summary of the geological characteristics of the deposit,the ore-forming laws are summarized by analyzing the sources of mineralizing substances,and the ore-forming process is further discussed.The study believes that the mineralizing substances are jointly provided by the carbonate rocks of the basement and the metamorphic rocks of the ancient land,indicating a diversity of material sources.The ore-forming process of the bauxite in the study area is constrained by various factors,and the final formation of the Yuzhou coal-underlying bauxite has experienced three stages:syngenetic sedimentation,burial modification,and preservation-erosion.
