摘要
成矿信息精细化研究是针对"现阶段矿产地质工作中过度依赖现代高端实验测试技术方法、过分追求利用有限的高精测试数据构建矿床模型,忽略了对更多成矿信息的精细化研究,难以直接指导探矿工程布置"的问题而提出的。成矿信息精细化研究突出研究成矿要素在有限时空尺度上的变化细节,尽可能利用勘查区内地质、物探、化探、遥感等资料,通过研究成矿信息的空间特征和变化趋势,还原成矿过程的细节。其四大研究特征是:重视大数据统计规律、重视多角度提取信息、重视研究勘查区尺度上地质信息的变化特征和重视研究成矿事件发生时的成矿过程细节。其五大研究要点是:识别控矿因素,分析矿床成因,研究矿质迁移富集机理,总结控矿因素在不同时、空尺度的变化规律,以及详细恢复成矿过程。研究路径是:对控矿因素进行专项深化研究、对实验室微观信息规律进行深入研究和对物化遥资料进行深入分析,为精细化研究提供更多信息。
The metallogenic information refinement is aimed at the major problems in the practice of geological exploration,such as,relying too much on modern advanced techniques and over valuing limited high-precision results in constructing ore deposit models.Whereas,detailed metallogenic information refinement is neglected.As a result,it is difficult to direct the actual prospecting engineering.The metallogenic information refinement highlights the details of the changes of metallogenic factors in limited space-time scales.The details of the metallogenic processes are surveyed by studying the spatial characteristics and trends of metallogenic information,the data of geological,geophysical,and geochemical prospecting as well as remote sensing in the working area.This method has four features:emphasizing the importance of large data statistics,extracting information from multiple perspectives,focusing on the scale variations of geological characteristics,and paying attention to the details of the metallogenic processes.There are five key steps in the refinement:identifying ore-controlling factors,analyzing the genesis of ore deposits,studying the mechanism of ore metal migration and enrichment,summarizing the major ore-controlling factors at different time and space scales,and deciphering the mineralization processes in detail.The research protocols include carrying out researches on ore-controlling factors,conducting thorough laboratory observations and tests,and analyzing the geophysical and geochemical results and remote sensing data,which will provide more information for ore prospecting and exploration.
