摘要
Abstract
The Zhuyuangou Mo -deposit in Ruyang, Henan Province is a porphyry type molybdenum deposit. By nearly three years of exploration in this deposit, more than ten thousand meters of drilling was done, and 8000 samples were collected. The results show that the ore bodies occur in the inner contact zones between the first - intrusion medium - to coarse - grained biotite granites and the second - intrusion fine - grained granite (Huoshenmiao) , with layer - like or lens shape. The Mo mineralization is closely related to the development of fissures. The ore bodies are generally 50 - 150 m thick with maximum 205.36 m. All the ores are of fine - grained granite - porphyry type. Studies on the petrology, mineralogy, geochemistry and geological characteristics suggest that the mineralized alteration is similar to that of the typical porphyry deposits. And the geochemical anomalies and granite - porphyry rock bodies are the principle prospecting indicators, which will be helpful for prospecting ore bodies in the Taishanmiao granite body.关键词
