But the tragedies of virginia tech ? and columbine , and nickel mines , pennsylvania , where five girls were shot at an amish school last year ? are not the full measure of the curse of guns 但是，弗吉尼亚理工大学的惨剧、哥伦比恩中学的惨剧，去年宾夕法尼亚州镍矿阿米许学校内5名女童被枪杀的惨剧，所有这些，并非“枪支灾祸”的全部。
This paper researches the synthetical ore - forming feature of cu - ni sulfided mine of baimazai in jin ping county . this nine is the main force of ni manufacturer . it is exact to look for succeed resource because of the resource has been drying up 本文研究金平白马寨铜镍硫化矿综合信息成矿特征，该矿作为云南镍矿主力生产矿山，由于资源已尽枯竭，急需找寻接替资源。
Beginning with the minerogenetic theory of mantle plume , the basic geological conditions of this type deposit can be summarized through studying typical copper - nickel sulfide deposits which have close bearing on continental flood basalt . in contrast with high - mg volcanic magmatic activity , it can be found that some intrusive rock bodies have ni - minerogenetic geology condiction . xilaping rocks in binchuan - chenghai region has some basic geological condiction and reflects some extent minerogenetic . all these testify this region has very larger potentiality of finding copper - nickel sulfide deposits 通过对研究区内与峨眉山玄武岩活动有关的高镁火山岩进行研究对比，发现区内与峨眉山玄武岩同期形成某些侵入岩体具有成镍矿(化)的地质条件。研究区内的昔腊坪岩体除了具有这些基本地质条件外，还显示不同程度的矿化，说明该地区作为寻找镍矿的靶区是有很大的潜力。
