以系统论思想对铅锌矿床类型进行划分。铅锌矿床分类的演化历史可分为两个阶段,目前或将进入以系统论、多成因、围岩、地球化学等特征相结合的第三阶段。在矿床成矿系列的系统论思想指导下,以多成因、围岩为主要分类因素,地质流体、成矿环境、成矿条件、地球化学特征等为次要因素,把铅锌矿矿床类型划分为4个矿床成矿系列和10个矿床类型(式):①热(卤)水成矿系列:海相沉积岩型(SEDEX)、海相碳酸盐岩型(MVT)、海相火山(-沉积)岩型(VMS);②岩浆成矿系列:花岗岩型、斑岩型、矽卡岩型、陆相火山岩型;③沉积成矿系列:砂(砾)岩型(TTS );④表生氧化成矿系列:残坡积型、砂矿型。该分类方案反映了矿床形成的客观规律和自然过程,揭示了区域内矿床之间的时空、成因关系以及成矿规律,扩展了思路,更符合实际情况。
以繫統論思想對鉛鋅礦床類型進行劃分。鉛鋅礦床分類的縯化歷史可分為兩箇階段,目前或將進入以繫統論、多成因、圍巖、地毬化學等特徵相結閤的第三階段。在礦床成礦繫列的繫統論思想指導下,以多成因、圍巖為主要分類因素,地質流體、成礦環境、成礦條件、地毬化學特徵等為次要因素,把鉛鋅礦礦床類型劃分為4箇礦床成礦繫列和10箇礦床類型(式):①熱(滷)水成礦繫列:海相沉積巖型(SEDEX)、海相碳痠鹽巖型(MVT)、海相火山(-沉積)巖型(VMS);②巖漿成礦繫列:花崗巖型、斑巖型、矽卡巖型、陸相火山巖型;③沉積成礦繫列:砂(礫)巖型(TTS );④錶生氧化成礦繫列:殘坡積型、砂礦型。該分類方案反映瞭礦床形成的客觀規律和自然過程,揭示瞭區域內礦床之間的時空、成因關繫以及成礦規律,擴展瞭思路,更符閤實際情況。

It is a controversial and inconclusive issue about the type division of lead-zinc ore deposit in China. There are two stages in the evolution of classification of lead-zinc mine.The first chassification stage is from 1900s to 1960s,based on magma monism,metallogenic temperature and surrounding rock.The second is from 1970s to 2000s,based on surrounding rock (ore-bearing rock series),multiple genesis and geochemistry.Present classification steps into the third stage,based on combined system with multiple genesis,surrounding rock and geochemistry.The system of metallogenic series is used as the guide,and based on mainly multiple genesis and surrounding rock,followed by geological fluid,metallogenic environment,metallogenic conditions and geochemis-try.The lead-zinc ore deposit types are divided into four metallogenic series of ore deposit and ten ore deposit types:① hot water (brine)metallogenic series:includes marine facies sedimentary rocks type (SEDEX),ma-rine facies carbonate rocks type (MVT)and marine facies volcanic (-sedimentary)rocks type (VMS);②mag-matic metallogenic series:includes granite type,porphyry type,skarn type and continental facies volcanic rocks type;③ sedimento-minerogenetic series:includes sandstone (conglomerate )-hosted type (SST);④ supergene oxidation metallogenic series:includes elluvial-deluvial type and placer type.The classification scheme of lead-zinc mine reflects objective law and the natural process of ore deposit forming,reveals space-time relations,origin relations and metallogenic regularity of ore deposit in the region,thus benefits the scientific research and indus-trial production.
