| 摘 要： | 本文基于萨吾尔地区目前发育的主要矿床(点)吐尔库班套铜镍矿点、阔尔真阔腊金铜矿床、布尔克斯岱金矿床、罕哲尕能铜矿床、塔斯特金矿床、黑山头金矿点、那林卡拉铜钼矿点等的研究,分析了区域矿化类型及成矿规律。认为萨吾尔地区矿床成因类型可分为三类,岩浆Cu-Ni硫化物矿床、斑岩型-浅成低温热液型Au-Cu-Mo矿床、与中酸性侵入岩有关的构造蚀变岩型Au矿床。矿化以Au、Cu矿化为主,Cu-Ni、Mo矿化次之。成矿时代分布在中泥盆世、早石炭世、晚石炭世,集中于早石炭世(354~336Ma)。空间上,岩浆Cu-Ni硫化物矿床分布于萨吾尔北部科克森套地区,斑岩型-浅成低温热液型Au-Cu-Mo矿床、与中酸性侵入岩有关的构造蚀变岩型Au矿床主要分布于萨吾尔山南部。成矿构造背景分别对应于区域中泥盆世岛弧环境、早石炭世岛弧环境、晚石炭世碰撞造山后环境。区域成矿规律显示了进一步的找矿潜力:萨吾尔北部科克森套地区发育的镁铁-超镁铁岩体的岩浆Cu-Ni硫化物矿床的找矿潜力;阔尔真阔腊-布尔克斯岱地区斑岩型-浅成低温热液型金铜矿床的找矿潜力;区域晚石炭世-早二叠世斑岩型Cu-Mo矿床的找矿潜力;萨吾尔断裂及其次级断裂控制范围内的Au-Cu找矿潜力。

| Abstract: | Since the 1980s, many new ore deposits (or occurrences) have been found in the Sawuer region of the West Junggar, but the geological characteristics, spatial and temporal distribution, tectonic setting and metallogenic regularity of the deposits are poorly studied, which constraints the further exploration works. This paper summarized metallogenic regularity of the deposits in the Sawuer region based on the research of the ore deposits (occurrences) in this area, including the Tuerkubantao Cu-Ni ore spot, the Kuoerzhenkuola Au-Cu deposit, the Buerkesidai Au deposit, the Hanzheganeng Cu deposit, the Tasite Au deposit, the Heishantou Au ore spot, the Nalinkla Cu-Mo ore spot. According to the genetic type of ore deposits, the deposits in the Sawuer region can be divided as following: the magmatic Ni-Cu sulfide deposit, the porphyry-epithermal Au-Cu-Mo deposit, and the tectonic-altered rock type Au deposit related to intermediate-acid intrusive rocks. The metallogenic elements mainly include Au and Cu, followed by Cu-Ni and Mo. These deposits were formed in the Middle Devonian, the Early Carboniferous, the Late Carboniferous, and manly concentrated in the Early Carboniferous (354~336Ma). Spatially, the magmatic Ni-Cu sulfide deposits are distributed in the Kekesentao region of the northern Sawuer, the tectonic-altered rock type Au deposits related to intermediate-acid intrusive rocks are distributed in the northern Sawuer region, while the porphyry-epithermal Au-Cu-Mo deposits are located at the southern margin of the Sawuer region. The deposits in this area were formed in Middle Devonian island-arc setting, Early Carboniferous island-arc setting, and Late Carboniferous post-collision environment. The metallogenic regularity implies that the Sawuer region has potential for further prospecting. The mafic-ultramafic intrusion in the Kekesentao region of the northern Sawuer should be regarded as favorable exploration target of magmatic Cu-Ni sulfide deposit. There has potential to further prospecting for porphyry-epithermal Au deposits in the Kuoerzhenkuo-Buerkesidai area. The Late Carboniferous-Early Permian intermediate-acid intrusive rocks in the Sawuer region have potential to further prospecting for porphyry Cu-Mo deposits. The area which developed the Sawuer fault and its secondary fault is favorable exploration target of Au-Cu deposits. |
