grain size analysis

Grain size analysis of well core or cuttings sample images.

This distribution was confirmed by the grain size analyses.

All sieves used in sample preparation and grain size analysis are made of metal rather than disposable nylon.

At a few places we were able to get samples for grain size analysis and to find enough charcoal for radiocarbon dating.

Grain size analyses confirm a predominantly medium and coarse sand size distribution.

Pe-Piper supervises students who prepare the samples for mineralogical, geochemical, and grain size analysis.

Grain size analysis; specific gravity; pH and grain size test in laboratory.

Grain size analysis.

Grain size analyses of screened fines closely parallel the native material used as cover material, as expected.

This is because sediment grain size analysis throughout a profile allows inference into the erosion or accretion rates possible if shore dynamics are modified.

In consequence some authors suggest that the conventionally applied log-normal probability law is not suitable for universal applications in grain size analysis.

The average grain size of the sediments disposed of at the five sites can be calculated using the grain size analyses conducted over the years.

Fifty seven samples were collected for grain size analyses, petrographic analyses, placer gold measurement, and indicator mineral identification.

Atterberg limits tests, water content measurements, and grain size analysis, for example, may be performed on disturbed samples obtained from thick walled soil samplers.

Keywords: closure, compaction, construction, dam, diversion, earth and rockfill, glacial till, grain size analysis, gravel, river, sand.

Our plan for today was simple: to see if we could map offset in any terraces, get stuff to date and get more samples for grain size analysis.

I managed to take one optically stimulated luminescence (O.S.L.) sample at the suspected delta, as well as a few samples for grain size analysis.

• Pebble counts, carbonate content analysis, geochemistry, grain size analysis, soil classification, cosmogenic dating and radiocarbon dating will be completed in 2002.

Since laser diffraction analysis is not the sole way of measuring particles it has been compared to the sieve-pipette method, which is a traditional technique for grain size analysis.

Laboratory techniques: CL and optical microscopy, SEM and EDX analysis, bulk-rock and clay XRD, soft sediment grain size analysis.

In order to plot the results of grain size analysis using the ratio scale it is necessary to use logarithmic scale graph paper for size so that visual equality is given to the scale divisions.

Grain size analyses showed that the thin varves were significantly finer than the thick varves and are inferred to reflect changed sediment inflow patterns that altered deposition and reduced the fidelity of the model.

The deposits appear better sorted than magmatic deposits in the field because of their fine nature, but grain size analysis reveals that the deposits are much more poorly sorted than their magmatic counterparts.

Grain size analysis of experimentally deformed Black Hills quartzite (see 4.2) shows that the recrystallized grain size is constant, i.e., the volume of recrystallized grains increases as recrystallization progresses but not the grain size itself.
