摘要
赵卡隆铁铜多金属矿床位于我国著名的“三江”成矿带上,有着长期找矿勘察的历史。本文在收集相关文献和资料的基础上,结合系统的野外地质调查和室内岩矿地球化学分析,对矿床形成的区域地质背景和成矿条件进行了研究,对该矿的成矿物质来源以及成因类型进行了探讨,从而进一步总结了矿床的成矿规律,建立了矿床的成矿模型。通过本文的研究,得出以下认识:
     1.通过搜集矿区资料及相关文献,结合矿区岩石地球化学特征,认为赵卡隆矿区处在北羌塘-昌都陆块北东边缘的江达-德钦岛弧带之中,成矿地质背景为弧后盆地。
     2.通过对矿区地质图的修测工作,确定了矿区地层新的层序关系,对矿区的构造系统及岩浆岩分布特征进行了研究。
     3.通过矿石地球化学特征的研究,认为矿区成矿物质主要来源于火山喷发活动,部分来源于地层,成矿母岩源区以壳源为主,成矿流体主要为岩浆水、地层水和循环海水的混合。
     4.结合矿区的成矿地质条件,分析了矿床的成因类型,并进一步探讨了矿床的成矿中心及分带特征。赵卡隆矿床属于海相喷流沉积-改造型铁铜多金属矿床。
     5.根据矿床地质特征和矿床成因分析,建立了矿床的双喷系统成矿模型,同时把成矿过程分成火山喷流沉积期和改造期两个期次。
The Zhaokalong iron-copper polymetallic deposit is located in the famous Sanjiang metallogenic belt, has a long history of the exploration and prospecting. Based on the collection of relevant literature and data, combined with systematic field investigation, petrographic study and geochemical analysis, this paper studied the regional geological setting of the deposit and its geological conditions, discussed the ore sources and the type of the deposit. Furthermore, it summarized the mineralization law, established the mineralization model. The major achievements as follows:
     1. by collecting data and literature, analyzing the geochemical characteristics, it showed that the deposit is located in the Jiangda-Deqin island arc, which is in the northeast edge of the northern Qiangtang-Changdu landmass, and its regional geological setting is back-arc basin.
     2. through the revision of the geological map, it identified the new sequence relationship of mining stratum, and studied the structure system of the mine and the distribution of igneous rocks.
     3. through the geochemical characteristics of ore, it showed that the ore sources mainly from volcanic eruption, partly from the stratum, the main source of the ore rock is the crust, and ore-forming fluid is a mix of magmatic water, formation water and circulating seawater.
     4. combined with the geological conditions, it analyzed the genetic type of the deposit, and explored the mineralization centers and zoning characteristics. The Zhaokalong deposit is a SEDEX-reworked deposit.
     5. according to the analysis of the geological characteristics and genesis, it established a deposit metallogenic model of double vents, while the ore-forming process is divided into two times, which are deposition of volcanic sedimentary exhalation and transformation.
