The significance of iron-stained foraminifera off SE Trinidad, West Indies, western central Atlantic Ocean Available to Purchase

BRENT WILSON
Published: 10 February 2010
Geological Magazine (2010) 147 (5): 728–736.
DOI: https://doi.org/10.1017/S0016756810000026
...BRENT WILSON Abstract Eleven samples of seafloor sediment were taken from water depths of 78–90 m within the Savonette Field, off SE Trinidad, western Atlantic Ocean. This surface sediment is relict, having been deposited during an early Holocene transgression. The samples yielded much iron-stained...

Distribution of iron-stained features in the Chalk based on re-logging chalk cores (Harris, 1998) compared with the stratigraphic ground model (Mortimore 1993b, 1994). This illustrates the concentration of such features associated with slickensided fractures in the Newhaven Chalk Formation and the fault zones, and the concentration of stained subhorizontal features in the Seaford Chalk formation that had been suggested by Mortimore (1993b).
