All rights reserved F Plagioclate Sodium-rich Biote Amphibole Color of rocks becomes increasingly dark Increasing silica content Ругскеле STUDENT SURNAME ..INITIALS STUDENT NO. Basalt Gabbro Peridotite Calcium-rich Olivine 1. BRIEFLY discuss the (i) environment and formation history (ii) rock texture, as well as (iii) exemplary rock indicated by the different arrows shown in diagram A. (12 marks) 2. Using diagram B, explain ALL the differences between the rocks formed by the two crystallization lines (black = dacite and red = dolerite) in terms of composition and texture. Mineral module abundance should be considered. (10 marks) 3. BRIEFLY describe what the Bowen's reaction series is, and how it is different from diagram B. (8 marks)
