肖板金矿床赋存于闽中前寒武系变质岩中 ,属于构造蚀变岩型金矿 .控矿构造是在变质岩构造基础上发育起来的蒲洋变质核杂岩构造系统之北西侧的剥离构造——低角度正断层系 .低角度断层不仅控制了矿体的形态、产状、规模和分布 ,其压扭性力学性质决定了交代为主的矿化蚀变类型 ,而且在成矿过程中也起到地球化学界面作用 .硫同位素、铅同位素、氢氧同位素、初始锶比值、稀土元素特征等资料反映出肖板金矿成矿物质主要来源于麻源群变质岩 ,并有少量岩浆物质的加入 ,成矿时代为燕山早期 .流体包裹体特征显示成矿流体主要来源于岩浆水 ,并有大气降水的混入 ,成矿温度 190～ 2 44℃ .结合构造演化和构造控矿特征分析认为肖板金矿床是受低角度正断层 (剥离断层 )控制的中低温岩浆热液型矿床 . The Xiaopan gold deposit occurs in the Precambrian metamorphic rocks in the Central Fujian and belongs to the structural altered rock type gold ore.The ore-controlling structure is the north west side of the structural system of the Puyang metamorphic core developed on the basis of the metamorphic rock structure The low-angle faulting not only controls the shape, shape, size and distribution of the ore body, but also the mechanical properties of the compression-torsion determine the type of mineralization alteration that is mainly accountable. In addition, The ore processes also play the role of geochemical interface.The data of sulfur isotope, lead isotope, hydrogen and oxygen isotope, initial strontium ratio and rare earth element characteristics reflect that the metallogenic material of Xiaopan gold deposit mainly comes from Mayuan group metamorphic rocks, The addition of a small amount of magmatic material, the mineralization age is the early Yanshan. The fluid inclusions show that the ore-forming fluid is mainly derived from magmatic water and mixed with precipitation, the metallogenetic temperature is 190-244 ℃ .Combining tectonic evolution and tectonic ore control The character analysis indicates that the Xiaopan gold deposit is a medium- and low-temperature magmatic hydrothermal deposit controlled by low-angle normal faults (pealed faults).
