摘要
辽宁省是我国金刚石重要的产区之一，探明储量占全国第一。辽宁金刚石发现于１９７１年，主要产于辽东半岛南部瓦房店一带，以金伯利岩管（脉）产出。金伯利岩体多分布于凹陷与凸起的交接带，受近东西断裂控制，与北东向（北北东向）构造交汇部位多控制岩管产出。目前发现三个矿带。根据成矿地质条件分析，辽宁省可划出五个Ⅲ级成矿远景区带，即大连—铁岭带，大连—丹东带，鞍山—宽甸—新宾带，山海关—北镇带，建平一旧庙带。目前的工作表明，上述五个远景区带都有进一步发现金刚石矿的可能。
iaoning province is one of important sources of diamond in China,its proven reserves rank first in China,In 1971,it was first discovered in kimberlite pipes (veins) mainly at Wafangdian,South Liaodong peninsula. The kimberlite bodies distributed along the joning belt of downwraping and upwraping areas, which the bodies were controlled by near EWtrend faults, especially in connecting area with NE(or NNE)trend tectonics there occurred more kimberlite pipes. So far, at Wafangdian there has been discovered 3 diamond ore belts. Analysis on oreforming geological conditions show that there are 5 Ⅲgrade oreforming prospective zones:DalianTieling zone,DalianDandong zone,AnshanKuandianXinbin zone,SanhaiguanBeizhen zone and JianpingJiumiao zone.
