Lithology and environment
| Primary lithology: | bioturbation,concretionary,volcaniclastic,shelly/skeletal,gray carbonaceous mudstone |
| Secondary lithology: | gray argillaceous mudstone |
| Includes fossils? | Y |
| Lithology description: "a 40-cm-thick, heavily trampled, light gray (N6) carbonate mudstone...The matrix is dominantly Ca-Mg smectite with a minor component of bioclasts and volcanic airfall ash material including zircons, plagioclase, and minor amounts of olivine. Darker gray, clay-rich (5GY4/1) mudstone infills the lowest levels of undulations in the trampled surface. Barite nodules are closely packed around bone material...The nodules have a granular texture with sparry calcite in dilational fractures." | |
