| 摘 要： | 卢氏—栾川地体是一个独立而独特的成矿地质单元，通过研究认为地体内铅锌矿床(点)的空间分布与燕山期中酸性小岩体关系密切。首次提出区内铅锌矿除分布于远离燕山期中酸性小岩体并受中、上元古界大理岩地层控制的脉状铅锌矿床外，还有矽卡岩型铅锌矿床呈环带状分布于钼(钨)矿床外围，这三种矿床共同构成一个与燕山期中酸性小岩体有关的成矿系列。其中矽夕卡岩型铅锌矿床的找矿前景广阔，是进一步找矿的重要类型。

| Abstract: | Lushi-Lanchuan terrain is an independent and particular ore forming geological unit. The special distribution of the lead and zinc deposits or spots are closely associated with the small Yanshanian intermediate-acidic rock bodies. It is suggested for the first time that the vein type lead and zinc deposits in the area occur not only away from the small Yanshanian intermediate-acidic rocks but also controlled by the marble stratum of upper Proterozoic Suberathum and skarn type lead and zinc deposit occur surrounding the molybdenum (tungsten) deposit in a ring shape. The above three kinds of deposits jointly formed an ore forming series related to the small Yanshanian intermediate-acidic rocks. The skarn type lead and zinc deposit is an important promising deposit type for further prospecting. |
