Annotatsiya
The article summarizes the petrographic, mineralogical and geochemical features of the Bokali granitoid intrusion situated within the Northern Bukantau structural-formational zone (Central Kyzylkum, Uzbekistan). Four intrusive phases were distinguished, from quartz diorite to fine-grained trondhjemite, plagiogranite and aplitic granite, with a four-impulse dyke complex. The hypabyssal level is confirmed by widespread hornfels development, the absence of potassic metasomatism and high magnetic susceptibility. ICP-MS analysis of 116 samples revealed a strongly contrasting geochemical field: Cu up to 3062 g/t, Mo up to 536 g/t, W up to 249 g/t and Au up to 0.104 g/t. The most reliable productive association is Cu-Mo-Au-As, whereas Mo-W-Re characterizes the high-temperature intrusive-contact stage. The deep, unoxidized stockwork zones of the south-western exocontact are identified as a priority exploration target.
