A slice of an object or substance that can be viewed under a microscope. Where is the thin section of that mineral specimen? I want to take a look at it under the microscope.

As the flow advances, the plastic reaches the thin section in Part B and therefore the required pressure to push past the thin section increases.
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.
Granulometric analysis of the thin section excerpts by QEMSCAN shows that, in aggregated form, the Bomen Yarabee and Bomen-Brucedale samples are comprised of a bimodal particle size distribution of very coarse sand ([greater than or equal to] 1000 [micro]m) and very fine sand to coarse silt.
Simple image analysis is used to acquire microfabric data and the microfabric distribution over the selected area of the thin section is visualized to compare it directly with till microstructure.
In the thin section some dolomite rhomb show zoning, filling showing dedolomitization in upper part.
A similar effect can occur with thick and thin sections because the thick section will typically be hotter on demolding than the thin section, even if the mold temperature is consistent.
The diagenetic fabric and its implications for the thin section porosity in carbonate facies of the Margala Hill Limestone in the Haripur area of North Pakistan is documented here.
1c), provided the angle of taper is sufficient and the source of the feed metal is at the heaviest section, Under these conditions, a favorable freezing pattern is assured because the metal that has flowed the farthest (and is therefore the coldest) is deposited in the thin section. In contrast to a heavy section, the thin section of molten metal has less heat to transmit to the mold before freezing can start.
The thin section freezes off fast to isolate the risers from the gating.
The thin sections preserved the internal structures of important larger foraminiferas and different genus of benthonic foraminifers such as Lockhartia, Operculina, Assilina, Miscellanea, Ranikothalia and Discocyclina.
They are relatively small and difficult to recognize in the thin sections. In the described section of SML they have a low abundance.
The metalcaster was afraid of the thin sections of the proposed casting and declined to quote.
The heating chamber has six independently controlled heating zones that surround the profile so more heat can be focused on areas with greater mass and less on the thin sections that are susceptible to over curing.
