Figure F32. Close-up of alternating darker and lighter seams in a grainstone turbidite. The grain size varies smoothly through this grainstone; the color banding is thought to result from diagenesis, including compaction and incipient pressure solution, rather than being a primary depositional feature. With further compaction, these seams would likely develop into stylolites similar to those found deeper in the succession at Site 1276 (Unit 2: interval 210-1276A-12R-3, 77-90 cm).
