Basalts of the Khodzhirbulak suite and assessment their feasibility for basalt fiber (Surkhantau mountains, southwestern shoots of the Hissar ridge)

The results of preliminary assessment of basalt of the Khodzhirbulakskoy Suite of Surkhantau Mountains for the basalt fiber production are presented. According to petro-graphic study, the rocks are described as basalts of amygdaloidal structure. On the base of content of the amount of glassy form and nodular calcite, three groups of basalts were identified. The inverse relationship between the bulk content of the volcanic rock and the content of calcite: the greater volume of volcanic rocks, the less content of cal-cite, and vice versa. The basalt material demonstrates average pH module of 3.52.
