At the late stages of the ore_forming process, the main ore_forming fluid was NaCl_H2O. According to characteristics of the fluid inclusions, high 3He/4He ratios and the existence of lots of mafic microgranular inclusions, the authors consider that the ore_forming materials of the Longshang tin_polymetallic deposit were derived from multiple sources. The ore_forming fluids were mixed with mantle, crust and atmospheric water. Under the control of igneous and surrounding rocks, the mantle ore_forming fluids played a key role in mineralization at the early stage of the ore_forming process.

根据流体包裹体特征，结合高3He/4He比值以及在锡田花岗岩中存在大量镁铁质微粒包体，笔者认为：锡田垄上锡多金属矿床成矿物质是多来源的，成矿流体为地幔、地壳和大气水的混合产物；锡多金属来源受岩浆和围岩控制，而在成矿作用过程中尤其是成矿早阶段，地幔成矿流体可能起到了积极的甚至关键的作用。

Kalamaili suture zone is an important plate boundary in north Xinjiang, and there are plenty of Neopaleozoic volcanic rocks around itThese volcanic rocks are enriched in LILEs and relatively depleted in HFSEs, and they are also characterized by high Nb, Zr, TiO2 contents and Zr/Y, Nb/Y ratios, and depleted SrNd isotopesThe characteristics of these volcanic rocks suggest that they were produced in postcollisional periodThe postcollisional volcanic rocks around Kalamaili suture zone become younger from west to east, which indicates that this suture zone entered postcollisional period gradually from west to east, and reflects that the Kalamaili Ocean had been closed gradually from west to eastAs to the Kalamaili suture zone in postcollisional period, the lithosphere extended and thinned, and the asthenosphere materials upwelled and melted partially, and intensive mantle convection occurred, leading to a plenty of mantlederived magmas underplating the suture zoneThe lithospheric mantle metasomatized by fluid in subduction period melted partially under decompression and high temperature, the resulting melts contaminated the underplating asthenospheric materials, and the erupted lavas became the Neopaleozoic postcollisional volcanic rocks

卡拉麦里缝合带是北疆的一条重要界线，沿该带广泛发育晚古生代火山岩。这些火山岩具有LILE相对富集、HFSE相对亏损的特征，且具有较高的Nb、Zr、TiO2含量和Zr/Y、Nb/Y比值，SrNd同位素主要表现出亏损的特征。综合分析表明，这些火山岩形成于后碰撞期。对卡拉麦里缝合带而言，从西向东后碰撞火山岩的时代逐渐变新，表明该缝合带从西向东逐渐演化进入后碰撞期，这从侧面反映了卡拉麦里洋盆是从西向东逐渐关闭的。对卡拉麦里缝合带而言，在后碰撞期，岩石圈伸展减薄，软流圈地幔物质上涌并发生部分熔融，加上地幔对流作用强烈，使得缝合带下产生了大规模的幔源岩浆底垫；先前在洋壳消减期被流体交代提取过的岩石圈地幔也在低压高温下发生部分熔融，形成的熔体混染了底垫的软流圈物质并喷发，形成了晚古生代的后碰撞期火山岩。
