新疆阿尔金山喀腊大湾整装勘查区位于阿尔金山山脉东段,北接塔里木地块,南邻柴达木地块(盆地)。大地构造位置属塔里木克拉通与阿尔金造山带的结合部位。在这一整装勘查区内,分布了大中型铁矿六处、中型铅锌矿3处。在2014-2015年的工作中,我们重点对喀腊达坂铅锌矿进行了调查。喀腊达坂铅锌矿产于寒武纪—奥陶纪拉配泉组二段火山—沉积岩系中。长期以来被认为是与火山喷流作用有关的层控铅锌矿床。我们通过野外构造蚀变填图(图1),发现矿体主要受到构造蚀变带控
The Xinjiang Arganye Ka lai Bay integrated prospecting area is located in the eastern part of the Altun Mountains with a northern boundary of Tarim and a south Qaidam parcel (basin). The tectonic location is a combination of the Tarim Kratong and the Altyn Tagh orogenic belt. In this wholly-owned exploration area, six large and medium-sized iron mines and three medium-sized lead-zinc mines are distributed. During the 2014-2015 work, we conducted a survey of the lead-zinc mine in Kaladabana. The Kaladabaran Pb-Zn deposit is found in volcanic-sedimentary rocks in the second member of the Cambrian-Ordovician Lazimequan Formation. It has long been considered as stratabound lead-zinc deposit related to volcanic jet flow. We constructed alteration maps (Figure 1) in the field and found that the orebodies are mainly controlled by tectonic alteration
