Fig. S3: Petrology and Nd–Sr isotopic composition of alkaline lamprophyres from the Early to Late Cretaceous Mundwara alkaline complex, NW India: evidence of crystal fractionation, accumulation and corrosion in a complex magma chamber plumbing system

Selected major oxide bivariate plots for the Mundwara lamprophyres and their comparison with other plutonic and volcanic rocks of the complex demonstrating a clear fractionation trend: (A) MgO (wt%) v. SiO₂ (wt%), (B) MgO (wt%) v. Al₂O₃ (wt%), (C) MgO (wt%) v. Fe₂O₃ (wt%), (D) MgO (wt%) v. TiO₂ (wt%), (E) MgO (wt%) v. CaO (wt%), (F) MgO (wt%) v. K₂O (wt%), (G) MgO (wt%) v. Na₂O (wt%) and (H) MgO (wt%) v. CaO/Al₂O₃. Data sources: essexite and gabbro (Pande et al. 2017) and mugearite and hawaite (Subrahmanyam and Leelanandam 1989)
