摘要
成矿规律对指导找矿不仅具有重要的理论意义,更具有重要的实际意义,尤其在当前乃至今后攻深找盲的重点找矿时期,意义更显重要。铅锌硫化物矿床是自然界中铅锌矿床的最主要矿床类型,其中方铅矿与闪锌矿是该类矿床中的最主要矿物,也是自然界中分布最广的含铅与含锌矿物。他们在自然界中紧密共生,可称为孪生矿物。同时在成矿中还与部分金属硫化物矿物及非金属矿物紧密共生,且具明显的分带规律,很好地揭示了该类矿床的成矿规律。加之,方铅矿与闪锌矿为肉眼可辩矿物,因此,其成矿规律对铅锌硫化物矿床的找矿及预测具有极为重要的地质意义。
Regularity of ore formation not only has important theoretical significance but also has very valid practical significance for ore-prospecting work,especially in present times and future.Sulfide deposit is the main lead and zinc ore types in nature.Galena and sphalerite are the most main minerals in lead and zinc ore types and widely distributed in nature. They exist closely symbiotically in nature,called the twin minerals.At the same time they also exist with part of metal sulfide mineral and non-metallic minerals symbiotically and regularly.The appearance reveals the deposit metallogenic regularities primely.Because galena and sphalerite can be seen by naked eye,the regularity of ore formation is very important for prospecting and calculating of such deposits.
