Patrick Quinn comes, in part, from that tradition and in his graduate textbook Ceramic petrography: the interpretation of archaeological pottery and related artefacts in thin section
, under review here--and in an earlier edited volume, Interpreting silent artefacts (Quinn 2009)--he addresses the need to train ceramic petrographers and to present examples of best practice.
In only one hotspot in the thin section
was Fe found in a phosphate binding (vivianite).
Silverthin provides a complete line of slewing ring turntable bearings and manufactures a wide range of thin section
ball bearings for the commercial, industrial, aerospace, and military markets.
Overlapping photographs covering a 3 mm x 4 mm large area of the thin section
were mounted in mosaic image using Adobe[R] Photoshop[R].
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.
The porosity determined from thin section
point counting is generally about 5% lower than that measured by the He-gas expansion.
In order to compare the kinetics of coalescence in bulk (annealing of granules) and in a thin section
an evaluation of the light micrographs [ILLUSTRATION FOR FIGURE 10 OMITTED] was attempted.
Petrographic thin sections
were taken from selected rock types and the results were used to complement the visual descriptions.
JPL engineers decided early on that thin section
bearings were the best way to handle the load in the small space available, and built the design around them.
For the rest of the analysis the chondrophore thin section
method was chosen as the aging method for the Greenland smoothcockles.
examination of the xenoliths revealed pyroxenes intermix with olivine.
