新余式前寒武纪含铁石英岩型矿床的褶皱构造复杂、奇特、多样。介绍了矿田东段矿床勘查中的构造,阐述新余式变质铁矿勘查中构造分析的作用。勘查实践表明,对具复杂构造背景的新余式铁矿,单纯依赖工程加密并不一定能对矿术作出符合实际的评价,结合物探等综合手段可以在扩大老矿区资源潜力的新一轮勘查中发挥作用。 The fold structure of the Xinyu Precambrian iron-bearing quartzite deposit is complex, peculiar and diverse. The structure of the ore deposit in the eastern part of the orefield is introduced, and the role of tectonic analysis in the exploration of the Xinyu metamorphic iron ore is expounded. Exploration practice shows that for a new type of iron ore mine with complex tectonic setting, simply relying on engineering encryption may not be able to make a realistic assessment of the mineral resources. In combination with geophysical prospecting and other comprehensive measures, it can be used in a new round of exploration to expand the resource potential of old mining areas Play a role.
