模糊ISODATA法在矿物包裹体成分研究中的应用

矿物包裹体是在成岩成矿过程中保留下来的原始物质，对其成分进行研究，可以提供诸如成岩成矿的物化条件、矿床成因、成岩演化等多方面的信息。就具体矿床而言，成矿物质常常具多源性，矿床的形成往往是各种因素共同作用的产物，其成因具有模糊性。如产于火山岩体或岩浆岩体附近的层控矿床，既具有沉积层控的特点，又受到火山活动或岩浆活动的影响，二者没有一个明确的成因界线。对此模糊现象，运用模糊ＩＳＯＤＡＴＡ法来讨论不同矿床矿物包裹体成分特点，以此探讨矿床的成因类型。

APPLICATION OF FUZZY ISODATA METHOD IN THE STUDY ON MINERAL INCLUSION COMPONENTS

Mineral inclusion is the primary matters preserved during diagenesis and mineralization.The study on the inclusion components can furnish various infomation such as physical chemical conditions of diagenesis and mineralization,deposit genesis and diagenetic evolution.On a specific deposit,its ore forming matters are often of the characters of various sources and the deposit formation is often contributed by various factors.The deposit genesis belongs to a fuzzy event.The stratum binding deposit occuring near volcanics and magmatites,for example,not only possesses sedimentary stratum binding characters but also is affected by volcanic activities or magmatic activities,that is ,the genesis is complex and fuzzy.Fuzzy ISODATA method is applied to discuss the characteristics of the inclusions of various deposits so as to explore the deposit geneses.
