From researches on volcanic rocks of a district and characteristics of mineral deposit, this paper analyses control factor of perlite and zeolite mineral deposit, and discusses about the origin of the deposit, as result, firmly determines that mineralizing primitive rock is vitreous rocks of acid volcanic formed by volcanic range, eruption of continental facies of marginal island-type. This Kind of rocks, in chemical element,is the one of extreme saturation in alkaline,among them the vitreous rocks of acid volcanic form perlite in certain conditions of temperature and pressure. Due to the differences in physical and chemical conditions, vitreous of volcanic clastic rocks forms zeolite and bentonite by way of volcanic glass remoulding.

本文从研究矿区火山岩矿床特征出发,分析了珍珠岩沸石矿床的控矿因素,并对矿床成因进行了讨论,认为矿区火山岩系一边缘岛弧型陆相喷发,由此所形成的酸性火山玻璃质岩石是成矿原岩,这种岩石在化学成分上属碱极度过饱和岩石,其中酸性火山玻璃质熔岩在特定的温度和压力条件下形成了珍珠岩;由于物理化学条件的差异,由熔结火山碎屑岩中的玻璃质形成了沸石和膨润土。

Western Tianshan, which is very rich in mineral deposits, is one of the most important metallogenic belts of Cu, Au and other ore deoposits in China The formation and characteristics of mineral deposits are intimately associated with the tectonic settings Under extensional tectonic background, the major ore deposits formed are Cu, Fe, Au and other deposits in intermediate basic and intermediate acid volcanic rorks with minor Cu, Mo, W, Pb Zn deposits related to intermediate acid intrusives and Cu Ni deposits associated with basic and ultrabasic intrusives And in expressive tectonic environment, the predominant ore deposits are porphyry, skarn and hydrothermal Cu and Au deposits associated with remelted granites, and small amount of reformed sedimentary Pb Zn and Cu deposits Further more, the principal characteristics of ore deposits formed in different epoches of the tectonic evolution are discussed And based on such features as tectonic settings, the target for mineral exploration is put forward in the north of the western Tianshan [

西天山金属矿产十分丰富,是我国重要的Cu、Au 等多金属成矿带。金属矿床的形成及其成矿特点与大地构造背景密切相关。在拉张大地构造背景下主要形成与中基性和中酸性火山岩有关的Cu、Fe、Au 等矿床,次为与中酸性侵入岩有关的Cu、Mo、W、PbZn 等矿床及与基性、超基性侵入岩有关的CuNi 矿床。在挤压大地构造背景下,主要形成与重熔型花岗岩有关的斑岩型、矽卡岩型和热液型Cu矿、Au 矿等,次为沉积改造型PbZn 矿和Cu 矿床。文中还讨论了大地构造演化的不同时期金属矿床形成的主要特点,并据大地构造背景等成矿条件对西天山北部进行了找矿预测。

National-class mineral resources geological materials are those that reflect the characteristics of mineral deposit formation of China and the levels of national mineral exploration and scientific and technological work.The mineral resources geological materials are permanently stored in the national geological material depository;so they need to be sifted.The sifting has two connotations:one is sifting of mineral deposits,i.e.the selected mineral deposits must be typical,representative and special ones;and the other is sifting of drill cores,i.e.the drill cores from the selected mineral deposits must be most representative.The paper illustrates the two connotation of sifting respectively and formulates the sifting criteria and work method so that the sifting of national mineral resources geological materials is regulatory and maneuverable.Finally,suggestions about the management are put forward.

国家级矿产实物地质资料是反映中国矿产资源成矿特点、展现全国矿产勘查与科技工作水平的实物地质资料。国家级矿产实物地质资料由国家实物库永久收藏管理,因此实物地质资料需要筛选。筛选包含2层含义,一是矿床的筛选,即具有典型性、代表性、特殊性的矿床;二是钻孔实物的筛选,即入选矿床最具有代表性的钻孔岩矿心。笔者对2层含义的筛选分别进行了阐述并制定了筛选依据和工作方法,使国家级矿产实物地质资料的筛选有章可循,具可操作性。最后,对全国矿产实物地质资料的管理提出了建议。
