河南省嵩县东湾—蛮峪金矿床地质特征及找矿意义

本文通过对东湾金矿矿区的地质概况、矿床地质特征的分析研究，得出东湾金矿是岩浆热液形成的构造蚀变岩型金矿，成矿时代属燕山晚期，燕山期岩浆活动不仅提供强大的热动力条件，而且还从矿源层中携带大量的成矿物质，在构造有利部位，尤其是NNE向断裂构造部位沉淀富集成矿，总结出了找矿标志和预测了今后的找矿方向。

Geological features and prospecting significance in Dongwan-Manyu gold deposit, Song County, Henan province

Based on the analysis and research on the geological setting and the geologic characteristic of mineral deposit in Dongwan gold deposit,it is concluded that the type of this gold deposit can be regarded as tectonically altered deposit formed by the activities of magmatic hydrothermal solutions, belonging to the Late Yenshan metallogenetic epoch. The magma activities not only provided thermodynamic energy, but also carried a great deal of metallogenetic materials from the source of ore-bearing layers to the tectonically favourable positions, especially in the NNE-trending faults, to precipitate, concentrate and form deposit. The prospecting criteria and the metallogenic prognosis are also summed up in the paper.
