The last two fibrous zones differ only in coloration, but show the same orientation of fibers or even their continuation. Generally, fibers are perpendicular to the dRAF zone, as in TD region in other corals discussed here ( -Fig. 7C, D +Fig. 7C, D ). Fractures and/or very distinct natural borders occur between some bundles of fibers ( -Fig. 7C +Fig. 7C , red arrows).

In SEM ( -Fig. 7A +Fig. 7A ), polished and etched sections show distinct negative relief of the dRAF zone (ca. 15–20 µm wide, often differentiated into dCRA), whereas fibrous zones show generally positive etching relief, except for the borders between layers of fibers. Fibers enclosing the dRAF zone form a distinct region ca. 20 µm wide, beyond which layers of fibers show much smaller (ca. 5 µm wide) growth increments. Longitudinal−radial sections .—In TLM, sections made in RAF plane show narrow dark brown “strands” (ca. 10–15 µm wide) arranged fanwise in the plane of the section ( -Fig. 7F +Fig. 7F ). Similarly, as in the longitudinal sections of the above described corals, the undulating course of the RAF in radial and longitudinal directions makes the dRAF visible only in some surfaces. In higher magnification, extremely fine (ca. 2 µm long), regular constrictions of “strands” are visible; however, perhaps because of the standard (not ultra−thin) thickness of the section, it cannot be clearly stated whether constrictions correspond to regular alternations of transparent colorless and more opaque brownish layers as in other corals. Also inconclusive in this respect were observations in MFM, however, similarly as in other corals investigated, only the areas of brownish “strands” exhibited bright green−yellow fluorescence ( -Fig. 7G +Fig. 7G ). In SEM, polished and etched sections show ca. 10–15 µm wide “strands” ( -Fig. 7B +Fig. 7B ) that generally have a negative etched relief; occasionally individual “strands” are not clearly delimited from each other, but rather form broader areas of negative relief. In the longitudinal direction “strands” show the alternation of zones more and less susceptible to etching. In places this alternation is very dense and regular (every 2 µm), and occasionally are less regular with wider zones more susceptible to etching (ca. 10 µm and more). diff --git a/data/65/55/80/655580222366FFDF3F730454FB2E9179.xml b/data/65/55/80/655580222366FFDF3F730454FB2E9179.xml index dfd35ba227a..0d1a96b9195 100644 --- a/data/65/55/80/655580222366FFDF3F730454FB2E9179.xml +++ b/data/65/55/80/655580222366FFDF3F730454FB2E9179.xml @@ -1,40 +1,44 @@ - - - -Three-dimensional micro- and nanostructural characteristics of the scleractinian coral skeleton: A biocalcification proxy + + + +Three-dimensional micro- and nanostructural characteristics of the scleractinian coral skeleton: A biocalcification proxy - - -Author + + +Author -Stolarski, Jarosław +Stolarski, Jarosław -text - - -Acta Palaeontologica Polonica +text + + +Acta Palaeontologica Polonica - -2003 - -2003-11-30 + +2003 + +2003-11-30 - -48 + +48 - -4 + +4 - -497 -530 + +497 +530 -journal article -1732-2421 +journal article +301807 +10.5281/zenodo.13388790 +81cfefb7-ec3a-4704-9df2-3ec6605154fd +1732-2421 +13388790 - + @@ -65,8 +69,8 @@ and .
