A Prospective Appraisal for the Exploration of Fiber-applied Basalts in Leibo Area, Sichuan Province

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.
