| 摘 要： | 本文在对小秦岭西南部灞源张家坪地区金矿形成地质背景的分析基础上，重点阐述了该区控制工业矿体的主要地质条件，包括控矿构造、岩浆岩、赋矿地层及热液活动等条件。最后通过对本区成矿地质条件及金矿化特征的总体评价，对金的成矿远景进行了地质预测，指出找到特大型或大型金矿床的希望不大，而可能在某些地带找到几处中等规模的矿床。

| Abstract: | In recent y6ars,a lot of goldr-ore deposits have been found among the Taihua group the Xionger group and the granitoids from the area of BayUan-Zhangjiaping in the southwestern of the Xiao Qinling ranges, but only a few of individual deposits have been initially ascertained about their scales. In order to prospect the minerogenetic prognosis of the gold-ore deposits, this paper deeply analyses the background of the goldore formation, and expounds the geological conditions, such as structures , maglnatic rocks, strata, active state of hydrothermal fluid and so on, which control the economic gold deposits. Lastly, according to the synthetic evaluation of both the metallogenitic conditions and the characteristics of gold minerolization, the gold minerogenetic prognosis has been made and the further directions and the sections for prospecting mineral deposits have been prospected in the paper. |
