通过对吉林省内金英金矿床与松江河金矿床2个硅化蚀变岩型金矿床地质特征的“类比求同”，总结出该类型矿床共同特点为：都与大型区域性断裂构造有关，控矿构造为大型区域性断裂构造的次级断裂构造，赋矿层位为元古代地层中的特定“界面”；矿体品位与黄铁矿等金属硫化物无关，矿体与围岩界线不明显，金呈独立矿物出现且成色较高，围岩蚀变以硅化为主，并见有碳酸盐化、高岭土化、重晶石化等，呈现出中低温矿物组合特点。该类矿床地质特征的对比分析对寻找类似矿床具有重要意义。

Analogy is made between the characterisitics of Jinying Gold Deposit and Songjianghe Gold Deposit , two silicification altered rock gold deposits .It is concluded that the same type deposit has such common characteristics as close relation to large scale regional fracture structures ,ore-controlling structures being secondary ones to large scale regional fracture structures ,occurrence being specific plane among Proterozoic layers ,grade of orebodies having noth-ing to do with metal sulfide like pyrites ,blur in the boundary between orebodies and surrounding rocks ,gold displaying higher grades as independent minerals ,silicification dominating the alteration of surrounding rocks while carbonation , kaolinization ,baratization coexisting ,a characteristic of medium-low temperature mineral association .The analogical a-nalysis among this type of deposits'characteristics bears significance of finding similar deposits .
