Figure 3.
Backscattered electron (BSE) images and energy-dispersive x-ray spectroscopy (EDS) spectrum of authigenic kaolinite (kaol) books. (A, B) Increasing magnification (mag) of the same location. (A) A BSE image of books filling a large void between detrital quartz (qtz) grains. The mag is 1600×. (B) Higher mag of (A) showing books truncated by adjacent aggregates of books. The mag is 6000×. (C) A BSE image of kaol books annotated to show crystal size. The mag is 2400×. (D) The EDS spectrum typical of authigenic kaol taken from an area in image (B). det = detector; HV = high voltage; vCD = low voltage–high contrast detector; WD = working distance.
