In situ 87Sr/86Sr composition, trace element composition and U-Pb ages of apatite of Kamthai (N25º38ʹ00ʹʹ, E74º55ʹ50ʹʹ) and Amba Dongar (N22º00ʹ, E74º05ʹ) carbonatite complexes, India

Supplementary materials 1 and 2 include one excel data file and a pdf file. The excel file contains eight data sheets that contain analytical condition for EPMA analysis, trace element data for standards/reference material run as unknowns with samples to calculate RSD during measurement using LA-ICPMS, U-Pb data for apatite form Kamthai and Amba Dongar, Sr isotope composition of apatite reference material with sample analysis using LA-MC-ICPMS, major oxide data, and Sr isotope composition of apatite in carbonatite and silicate rocks from Kamthai and Amba Dongar complexes analyzed in this study. The pdf file contains figures to show spot locations on apatite grains, and Sr isotope composition, PM and CM normalized trace element patterns for apatite to support the discussion part.
