Fig. 2From: Lithological structure of western Pacific lithosphere reconstructed from mantle xenoliths in a petit-spot volcanoPetit-spot knoll and sample descriptions. a The small conical petit-spot knoll and sampling point of the 6K#1466 dive by SHINKAI 6500 (pink stars). Three basaltic lavas, 6K#1466R6-001, R7-001, and R7-003, were collected from locations near the western slope of the knoll. b, c The representative basalt sample (6K#1466R6-001) and its photomicrograph. d–g The occurrence of ultramafic xenoliths: d MPSX-PR1, e MPSX-PR2, f MPSX-PX1, and g MPSX-PX5Back to article page
