摘　　要：吉林省珲春东部地区是一个重要的金矿成矿区和生产区。我们首次在该区应用综合信息矿产预测理论和现代金矿成矿理论 ,建立了综合信息找矿模型 ;划分了 1 0个矿床地质单元 (找矿靶区 ) ,提取了 41个变量和赋值 ,利用多种数学模型刻划了单元的资源特征 ,对该区金矿进行了定量预测。我们将 1 0个地质单元划分为 6个 I级单元和 4个 级单元 ,确立了 6个 I级单元具有中大型金矿找矿前景。对 6个 I级地质单元进行了地质解释 ,提出了对找矿靶区进行勘查的有效程序和方法。The east of HunChun in Jilin province is one of the most important gold metallogenetic and producing district.Appling comprehensive information prognosis and gold modern theory of metallogeny,Authors set up the synthetic information model of prospecting gold deposits,and delineated ten geologic units of gold deposits(prospecting gold targets),and determined many geologic variables and their values,and described gold mineral resources of geologic units and rationally predicted gold mineral resources by many mathmatical methods.in this district for the first time.Ten geologic units are divided into six I grade units and four Ⅱ grade units.The six I grade units are gold prospecting targest with middle or large deposits.Moreover,the geologic units are interpreted,and we built up the effective course and methods of prospecting gold deposits in the targets.
