摘要:
四川省雷波地区位于康滇古陆东缘,该区峨眉山玄武岩为典型陆相喷发玄武岩，属喷溢-溢流相。根据峨眉山玄武岩的分布特征，在全区选取3条具有代表性的地层剖面为研究对象，通过剖面测量、样品测试及显微镜下观察，对雷波地区纤维用玄武岩的找矿远景进行了初步分析，认为：①雷波地区峨眉山玄武岩岩石类型主要为致密块状玄武岩、杏仁状玄武岩及斑状玄武岩，其中致密块状玄武岩是本区主要的纤维用玄武岩矿石类型；②雷波地区致密块状玄武岩主量元素特征为：w(SiO2) =49.81%，w(Al2O3) =13.15%，w(CaO)=7.71%，w( MgO)= 4.32%，w(Fe2O3+FeO) =12.66%，w(K2O+Na2O) =4.25%，w(TiO2) =3.93%；与邻区同构造位置成功拉丝的纤维用玄武岩对比，其岩石学及主量元素特征基本一致，符合拟定工业指标，能够进行连续纤维拉丝，厚度191.77~886.60 m，具有较大的找矿远景，对四川省尤其雷波地区玄武岩纤维产业发展起积极推动作用。
Abstract:Leibo area is located in the eastern edge of KangDian palaeocontinet, Emeishan basalts in the area are formed probably by typical terrestrial eruption, effusive facies. According to the distribution characteristics of Emeishan basalts, select 3 representative stratigraphic sections in the whole area as the research object, through profiling, sample test and microscope observation, the prospecting prospect of fiber basalt in Leibo area has been preliminary analyzed, It is suggested that: ①The rock types of Emeishan basalts in Leibo areamainly include compact basalt, amygdaloidal basaltand porphyritic basalt, the compact basalt is the main type of fiber-produced basalt in this area; ②The results show that major elements of compact basalt in Leibo area are composed of 49.81% SiO2, 13.15% Al2O3, 7.71% CaO, 4.32% MgO, 12.66% Fe2O3+FeO, 4.25% K2O+Na2O, and 3.93% TiO2; Compare with the fiber-produced basalt that has been successfully drawn in the same structural position and the neighboring area, the petrology and major element characteristics are basically the same, in line with the proposed industrial standard, they are capable of continuous fiber drawing, and the thickness:191.77~886.60 m, It has a great prospecting potential, It will play an active role in promoting the development of basalt fiber industry in Sichuan Province, especially in Leibo area.
