对比研究是矿产勘查评价的有效途径之一，结合系统扎实的地质工作和辩证的对比研究思维，通过将云南大民太铜镍矿床与国内成矿条件相似的典型岩浆型 Cu-Ni-PGE 矿床进行对比研究，分析其地质特征、地球化学特征以及找矿潜力。结果表明：“小岩体成大矿”并非普适性规律，大民太铜镍矿床为岩浆单式侵位就地熔离成矿作用的结果，矿化表征出铜镍硫化物矿床与钒钛磁铁矿床的过渡类型矿床的特点，与香山西复合型矿床具有可对比性，具有一定的找矿潜力。

Comparative study is one of the effective ways to conduct mineral exploration and evalua-tion,combing with system and solid geological work and dialectical comparative study thinking,the Dam-intai Cu-Ni sulfide deposit in Yunnan province and the typical magmatic type Cu-Ni-PGE deposits with the similar ore-forming conditions in domestic are conducted comparative study to analyze the geological characteristics,geochemical characteristics and prospecting potential of the Damintai Cu-Ni sulfide deposit in Yunnan province.The results show that the law of small rock mass becoming great ore deposits is not u-niversal,the Damintai Cu-Ni deposit in Yunnan province is the product of place liquation mineralization by magma single-emplacement,the mineralization of the Damintai Cu-Ni deposit in Yunnan province with the transitional type deposit characteristics of Cu-Ni sulfide deposit and V-TI magnetite deposit,it is has a certain degree of comparability to Xiangshanxi composite type deposits,therefore,the mining area of the Damintai Cu-Ni deposit in Yunnan province has a certain prospecting potential.
