  1. Lithogeochemistry of the sulfide - bearing mafic - ultramafic rock at baimazhai, jinping, southern yunnan

    超鎂鐵質巖石有關的礦床類型
  2. These deposits, which can be obviously divided into basic and acid volcanic types, are present in the carboniferous bi - model volcanic series and occur along two horizons, i. e., the lower carboniferous mafic volcanic rock and the upper carboniferous felsic volcanic rock

    這些礦床產在石炭系雙峰式火山巖系之內，沿著下石炭統基性火山巖和上石炭統酸性火山巖兩個層位產出，分別以玄武巖和流紋巖為容礦主巖，可以明顯地分成基性火山巖型和酸性火山巖型兩種類型。
  3. Wenquan granite is composed of two end - member rocks, one is the host rock of the acid end - member, and the other is the microgranular mafic enclave

    摘要溫泉花崗巖體由酸性端元的寄主巖石和暗色微細粒鎂鐵質包體群及基性巖墻群組成。
  4. Throughout researching it has been found that three main types of copper deposits, which mafic - ultramafic rock, marine volcanic rock and porphyry, with middle proterozoic, paleozoic and mesozoic in gansu, china. the cu - bearing formation, deep major faults and late structural - magmatic zones formed in specific geotectonic setting are main ore - controlling and metallogenic factors for copper, gold and polymetallic minerals in this area, and their convergent positions are effective ones formed ore bodies in space

    通過研究認為：鎂鐵質-超鎂鐵質巖型、海相火山巖型及斑巖型三種銅礦類型，是甘肅的主要銅成礦類型，其主成礦階段為中元古代、古生代以及中生代；特定大地構造背景下形成的含礦建造、區域性深大斷裂以及後期斜向構造-巖漿活動帶，是該區銅、金及多金屬成礦的主要控礦因素，三者在空間上的復合是礦床體形成的有利部位。
