It is an awkward group, stocked with blurry, elemental figures often battling their way forward through a welter of abstraction.

The focal length of the lenslet array is 1 cm and the pixel number of each elemental image is 75 × 75. Figure 5 shows the EIAs captured by the pickup system.
The dark grains indicate the absence of elemental Zn (Figure 4c) and the presence of Se and Pb (Figure 4d, e).
XRF offers the possibility of mapping and localizing pigments, thereby producing an elemental map (Figure 3).
The same evaluation was carried out using spectral data instead of elemental compositions (Figure 3).
Inspection of an Eh-pH diagram for the S-H2O system indicates that the low-pH microcosms are in fact near the stability field for elemental sulfur (Figure 5).
Elemental maps (Figure 7) of C, O and Fe for the samples prepared from composite targets containing 1 wt.% (B) and 5 wt.% (C) γ-Fe2O3 are also shown.
In the following Au and Ag elemental mapping (Figure 4b,c), it is observed that both Au and Ag disperse in or on these nine nanodisks, suggesting that no singular Ag nanodisks were formed.
Based on the major elemental compositions (Figure 4b), we also obtained an emergence age (i.e., the transition from marine to freshwater) of 3,382 to 3,560 cal BP (2σ); the median age of 3,471 cal BP occurs at a depth of 46 to 49 cm.
