Abstract

We report an exhaustive list of coring disturbances from the entire collection of piston cores collected during Integrated Ocean Drilling Program (IODP) Expedition 340. Expedition 340 cores contain numerous coring disturbances resulting from the particularly thick and coarse granular material cored. Overall, 23%32% of the recovered core length is disturbed. Here, coring disturbances are grouped into fall-in and flow-in classes, and uncertain intervals are distinguished from those with clear evidence of coring disturbances. Fall-in corresponds to fallen material atop the core, chiefly from hole collapse. Flow-in includes basal flow-in, which occurs at the bottom of a core, and midcore flow-in, which corresponds to injection of sand into the in situ core stratigraphy. Basal flow-in is likely to occur in conditions of partial stroke, whereas midcore flow-in seems to occur where the core material was stretched during recovery.
