Piecing together the puzzle of Pangea

Researchers aimed to investigate Pangea’s plate thickness.

Thick black and magenta lines show northern boundaries of India and Arabia and southern boundary of Eurasia. Dashed light-green line marks outer margin of Pangeides active margin. Dashed yellow line shows approximate boundary between active margin and arc of thick lithosphere. Dashed dark-green line outlines area underlain by thinner lithosphere that now underlies North Africa, Arabia, and western Europe. Inset shows same reconstruction without any lithospheric thickness contours. NA--North America;, Eu--Eurasia; SA--South America; Af--Africa; An--Antarctica; Au--Australia. Click image to expand.
