本义从产于石炭纪地层小的含银黄铁矿矿床的土要地质特征、侵入岩与成矿关系以及稳定冈位索特征等人面的研究提出，该类矿床具有明显的沉积特征；成矿元素流主要来自石炭纪海水，成矿金属元素主要来自下优地层，成矿流体以大气降水为主，成矿热动力主要是岩石中积累的热能和穿切地壳易透区下面而来的热能（包括海西期火山活动所形成的地热场）；矿床属海底喷气（热水）沉积成国．燕山期侵入岩对其有不同程度的叠加改造。同时阐述了该类矿床的成因机制。
Based on the study of the geologic features of the earthy deposits, the relationship between intrusive rocks and metallogenesis and the characteristics of stable Okazaki lines, the authors suggest that such deposits have obvious sedimentary characteristics; The ore element flow is mainly from the Carboniferous seawater. The metallogenic elements of the ore are mainly from the Xiaoyou Formation. The ore-forming fluid is dominated by atmospheric precipitation. The thermodynamic power of mineralization is mainly the accumulated thermal energy in the rock and the underlying peridotite permeable zone Thermal energy (including the geothermal field formed by the Hercynian volcanic activity); deposits belong to the oceanic jet (hot water) deposits into the country. Yanshanian intrusive rocks have different degrees of superposition and transformation. At the same time, the genesis mechanism of this kind of deposit is expounded.
