| 摘 要： | 近年来经初步工作在陕西灞源地区查明、发现小型金矿床、矿点共31处，本文根据矿点本身的各种特征，用模糊综合评判法对矿点矿化强度进行了评价和排序，以此为基础建立单元含矿性变列，筛选出成矿环境变量16个，用逻辑信息法在区内圈出金矿远景区A类40km-2，B类46km-2.为本区金矿进一步勘查工作部署提供了依据。

| Abstract: | Bayuan region，shaanxi Provhce，is the southwest portion of the Xiaoqiding gold metal-logenic belt．Over the last several years 31 gold ore deposits and occurrences have been dis-covered in this region，In light of mainly indirect criteria，this paper makes an evaItiation and classification of the mineralization quality of the occurrences．Based on this，with 16 geologicvariables taken into account，the paper contructs variation sequences of ore-forming meritsof the cells and delineates gold prospective areas of various grades；The methods of ftizzy syn-thetical judgement and logic-informational analysis are employed. |

| Keywords: | Shaanxi Bayuan vein gold deposit metallogenic prediction fuzzy syn-thetical judgement logic-informational analysis |
