苏联图瓦自治共和国东南桑吉连高原地区,发现了大约20个霞石岩岩体,其时代为中-晚古生代。其中一部分岩体是铝工业的优质霞石矿床。碱性霞石岩侵入体产于前寒武纪古老基底的桑吉连中间地块。该岩体为以北西向为主的断裂破坏系统所复杂化。岩体的地质位置主要受深大断裂弱化带所控制,多半是在弱化带与近南北向局部断裂的结合部位。岩体呈板状或层状,形成1～20
Some 20 nepheline rocks were found in the Sangjili plateau in the southeast of the Tuva Autonomous Republic of the Soviet Union. Its era was Meso-Late Paleozoic. Some of these rock masses are high-quality nepheline deposits of the aluminum industry. Alkaline nepheline intrusions occur in the middle of the Sangjilian block of the ancient Precambrian basement. The rock mass is complicated by the northwest-oriented fracture failure system. The geological location of the rock mass is mainly controlled by the deep fault weakening zone, mostly in the weakening zone and the near southern-northern part of the fracture site. Rock was plate or layered, forming 1 ~ 20
