Samples for thin section
production were taken from the reddish upper part of the Yarabee parna deposit and from the centre of the Willis parna deposit (Table 1).
Carbonate cements were investigated by using epoxy-impregnated thin sections
, cathodoluminescence, and SEM/EDX images.
They are relatively small and difficult to recognize in the thin sections
. In the described section of SML they have a low abundance.
The microstructures were counted in the thin section
area of 23 mm x 16 mm.
groenlandicus: (1) reading the external rings on the shell, (2) counting the growth rings on thin sections
of the chondrophore, and (3) counting growth rings of whole shell sections.
A microtome blade was used to produce thin sections
of southern pine sapwood about 200 to 250 [micro]m thick.
Sample 40PK27-1--The sherd from which this thin section
was made was initially described, in hand sample, as having a plain (non-decorated) outer surface tempered with limestone grit, primarily sand-size particles of crushed rock.
A detailed study was conducted after collecting systematically more than 30 rock samples in vertical thickness of aprox.31.45m and studying selecting more than 30 thin sections
A similar procedure was adopted for the thin section
examination of the xenoliths revealed pyroxenes intermix with olivine.
Under the thin section
, quartz and dolomite were found in trace amount in the form of fine-grains while chalcedony, crystobalite and other deleterious minerals were not observed.
Decreasing the amount of venting in the thin section
of the pattern had a dramatic influence on the occurrence of voids in that area.
However, all these parameters were not observable in thin sections
simultaneously; therefore, the identification is supported further by comparing the foraminiferal specimens of the Mughal Kot Formation with thin section
illustrations of the same species in standard literature (e.g.
