Figure F28. Complex intrusive contacts. A. Composite dike. The chilled margin forms a convex lobe, indicating that the host rock was still ductile during the intrusion (interval 309-1256D-155R-1, 8390 cm). B. An inner sparsely phyric dike intrudes a sparsely phyric spherulitic chilled margin, which is different from the aphyric host rock. Therefore, in this piece, two subsequent intrusive contacts are recorded (interval 309-1256D-161R-2, 08 cm). C. Lobate contact with brecciation of the external chilled margin and dispersion of the small clasts in the host rock observed (interval 309-1256D-163R-1, 112122 cm).
