limestone (biosparite). Figure

shows 'Petit Granit'
(Carboniferous), a hard polishable, grey fossiliferous
limestone from Belgium. Figure
64
shows 'Jura'
limestone, which is a hard compact, beige biopelmicrite.
Figure
65
shows 'Caliza Capri' from Spain, which is a
cream/buff limestone (oobiosparite). Figure
66
shows
'Moleanos' from Portugal, which is a compact, buff-
coloured limestone (oosparite). Figure
67
shows 'Rossa
Verona' from Italy, which is a hard polishable, orange
limestone (biosparite) with occasional stylolites.

'Petit Granit' limestone (Belgium) consisting of
bioclasts (mainly crinoids and shells) that are well
cemented by sparry calcite; XPT, ×35.

64
'Jura' limestone (Germany) consisting of small shell
fragments (pink) and micritic peloids (brown), cemented
by microcrystalline calcite (brown). A vein of coarsely
crystalline calcite is seen in this view; XPT, ×35.
65
'Caliza Capri' limestone (Spain) consisting of
rounded ooliths and bioclast allochems (brown)
cemented by sparry calcite (pink); XPT, ×35.

'Moleanos' limestone (Portugal) consisting of
ooliths (brown) cemented by sparry calcite (pink);
XPT, ×35.
67
'Rossa Verona' limestone (Italy) consisting of fine
shell fragments supported by a matrix of
microcrystalline calcite (brown). A stylolite running
across the field of view is filled by red iron compounds
and rhomb-shaped dolomite crystals; XPT, ×35.
