内蒙古东部森林沼泽区1:20万区域化探工作回顾

通过对内蒙古东部森林沼泽区开展1:20万区域化探4个不同阶段工作方法技术及效果的回顾和总结,认为在不同时期的工作方法技术随着对森林沼泽区这一特殊景观的认识不断加深,其工作方法技术也在不断改进,发现矿点8处、矿化点17处,其中,银锌矿17处、金矿1处,取得了较好的地球化学勘查成果,所完成图幅较客观地反映了工作区区域构造、成岩成矿作用的表层地球化学面貌,大大提高了地球化学信息的可靠性和真实性.

A REVIEW OF 1:200 000 REGIONAL GEOCHEMICAL EXPLORATION IN THE FOREST-SWAMP AREA OF EASTERN INNER MONGOLIA

1: 200 000 regional geochemical exploration work has been carried out in the forest swamp area of eastern Inner Mongolia, which can be divided into four different stages. Based on a review of the techniques used and results obtained in these four different stages, it is held that, with the gradual deepening of the understanding of such a specific landscape, the working methods and techniques have been improved steadily. Eight ore spots and seventeen mineralized spots have been discovered, of which there are seventeen silver zinc deposits and one gold deposit. The result of geochemical exploration is quite satisfactory and can objectively reflect the surface geochenmical characteristics of structures and rock-forming and ore forming processes in the working area, thus remarkably raising the reliability and truthfulness of geochemical information.
