| 中文摘要:贝勒库都克锡矿带是我国新发现北方地区第一条独立锡矿带．由与S型黑云母花岗岩有关的石英脉型锡矿及与A型花岗岩伴生的锡矿床和砂锡矿组成其成矿系列。成矿时代属海西晚期。准噶尔与野马泉两地块相撞焊接．于碰撞褶皱带形成区域造山期花岗岩．热量聚集熔化产生改造型含矿花岗岩株，局部拉张产生含矿A型花岗岩，二者经碱质交代-酸性淋滤成矿作用，使锡活化迁移集中富集而形成有关锡矿床。 |

| THE GEOLOGICAL FEATURES AND ORIGIN OF THE BEILEKUDUK TIN METALLOGENIC BELT |
|
|
| Abstract:The Beilekuduk tin metallogenic belt is the first independent tin metallogenic belt discovered in northern China, in which there occur the Beilekuduk, Sareshik, Kamst and Ganliangzi tin deposits and several tin occurrences. It extends a NW direction in the Kalamaili deep fault. Tin-bearing granites are mainly represented by highly differentiated ultraacid and akalirich S-type biotie granite sotcks of Late Hercynian age, but the Sareshik tin deposit is an independent tin deposit related to Hercynian A-type granites discovered for the first time in China. |
