通过成矿地质条件分析，内蒙古自治区科尔沁右翼前旗刘店沟矿床的形成与晚侏罗世陆相中酸性火山岩及早白垩世黑云母花岗闪长斑岩、黄铁矿化花岗闪长斑岩关系十分密切，北东、北西向构造为区内主要的控矿构造，北东向构造为导矿构造、北西向构造为容矿构造，因此，地层、岩浆岩、构造“三位一体”控矿为本区控矿规律。成矿时代为早白垩世晚期。成因类型为岩浆热液型。
通過成礦地質條件分析，內矇古自治區科爾沁右翼前旂劉店溝礦床的形成與晚侏囉世陸相中痠性火山巖及早白堊世黑雲母花崗閃長斑巖、黃鐵礦化花崗閃長斑巖關繫十分密切，北東、北西嚮構造為區內主要的控礦構造，北東嚮構造為導礦構造、北西嚮構造為容礦構造，因此，地層、巖漿巖、構造“三位一體”控礦為本區控礦規律。成礦時代為早白堊世晚期。成因類型為巖漿熱液型。

Through the analysis of metallogenetic geological conditions, the formation of Liudiangou silver deposit in Horqin Right Front Banner of the Inner Mongolia related to the Late Jurassic continental facies intermediate acidity volcanic rock and the Early Cretaceous biotitic granodiorite porphyry, pyritized granodiorite porphyry. The NE, NW direction structures are the main ore-control structures in the region, the former is ore-bringing structure, the latter is host structure, therefore, strata, magmatic rocks, structures of“the Trinity”ore-controlling are ore-control regularity in this area. The metallogentic epoch is the late stage of the Early Cretaceous. Genetic type is a magmatic hydrothermal type.
