摘要
小佟家堡子金银矿床赋存在辽河群大石桥组ＰｔＬｄ５３和ＰｔＬｄ４３的互层带之中。矿体受层间滑脱构造控制。容矿岩石以白云石大理岩和硅质岩为主，矿体呈层状、似层状。矿石中的金以不可见金为主，金含量与毒砂关系最密切。成矿物质来源于地层———即海底火山喷气和喷流作用形成含矿热卤水，经运移在海盆边缘沉积形成矿源层或浓集区，经区域变质作用和岩浆作用的改造，在印支期就位。矿床成因类型为同生沉积变质岩浆热液叠加再造型金银矿床。
Xiao Dong Jia Bao Zi gold silver deposit occurs in interlay belt of PtLd 4 3 and PtLd 5 3,Dao Shi Qiao series,Liaohe group The orebody is controlled by interlayer slip tectonics.The ore containing rocks are mainly dolomite,marble and silicic rock and the orebody presents beddedness or likelihood stratification.The gold in ore are principally invisible.Its gold content is closely related to arsenopyrite The mineralized matter mainly stemmed from strata ,that is to say,the gas and fluid spraying process of seabed volcano formed ore containing hot brine,and the hot brine ,through movement,deposited on the fringe of sea basin to from ore source bed or concentration area,again,the ore source bed took its place in Indo Chinese epoch through the remoulding by metamorphic process and magmatic process.The genetic type of the ore deposit is regenerative type of contemporaneous deposition metamorphism superimposition of magmatic hydrothermalism
