The fine breccia limestone was mostly composed of calcite oolites with tuff debris (Fig.
This is supported by the wide distribution of clastic carbonate material, oolites, stromatolites and vertical branching channels (burrows or 'rhizoid' structures), sometimes even at a distance from reconstructed sea shores.
But Minagish oolites contain high-sulphur oils with toxic hydrogen sulphide.
The studied succession consists of 7 lithofacies expanded from Barnolas and Simo (1987) including: boulder-pebble conglomerates, graded pebble conglomerates, graded peloidal-ooid packstones, graded oolites, calcilutites, Posidonia coquina and cherty mudstones.
The south, meanwhile, is a low flat rocky plain, composed by Pliocene through Quaternary limestone and oolites covered by dense forests and bushes.
Upper Paoli beds reveal a well developed oolite bar containing large undeformed oolites with thick cortical rinds, in a very clear spar cement.
This is not necessarily the case for higher parts of the deposits, comprising unaltered calcite oolites (Fig.
Larsen (1942b) made a detailed study of the paragenetic relationships in the evolution of variscite nodules in the Clay Canyon deposit, identifying six stages: (1) variscite formation, followed by fracturing and the introduction of thin black quartz veinlets; (2) banded minerals, primarily crandallite, millisite and wardite, replacing and enclosing variscite while opening up cavities through shrinkage (some variscite nodules were entirely replaced by crandallite); (3) formation of free-growing crystals of gordonite, englishite, montgomeryite and probably overite and kolbeckite in cavities; (4) a minor reversion to crandallite formation from solution as isolated oolites; (5) apatite-group minerals; and finally (6) the limonitic phase (limonite is not present inside any of the nodules).
In the Smackover oolites, which were used to construct the porosity/depth curves in Figure 3, physical and chemical compaction combined account for a loss of 33% of the original 45% porosity (Heydari, 1997).
The oolites at Cedar Hill and Russell Mountain laed us to the conclusion that these bedded ores are of undoubted sedimentary origin.
(6) 1.2 m--dark brown varigrained pelletal-biodetrital dolofloatstone with oolites, small pebbles of light grey dolomudstone and rounded bivalves, gastropods, ostracods (Herrmannina), intercalated with light grey dolomudstone.
