Micrographs from those working in Soil Micromorphology will be dispalyed on this page.
It is hoped that this will be a regular feature and perhaps
something which will promote discussion. Contributions for future
months are welcome.
[for details -see below]
The first micrograph from Paul Goldberg was displayed for the
first time on 27th November 1997. This is a test to check that
the system works, - in particular to assess whether there are
difficulties encountered by those overseas because of the size of
the image.
All the images will be displayed in miniature form on this page.
Please click on the miniature to display the full image. It
should also be possible for you to download the image in the
normal way.

Micrograph supplied by Dr Paul Goldberg: Department of
Archaeology, Boston University, 675 Commonwealth Ave, Boston,
MA2215, USA: Email: paulberg@bu.edu
The micrograph shows reworked hearth material (charcoal,
burned clay soil pellets and some ash) from Dust Cave, Alabama.
This is a Palaeoindian through Archaic site in Northern Alabama,
excavated by Dr. Boyce N. Driskell, University of Alabama,
Tuscaloosa.
This is quite
a large image and may take a little time to load. It is displayed
in full 16.7 million colours. If problems of loading arise, it
will be possible to reduce the size by about 40% by reducing the
number of colours to 256. Please inform geo.micro@uea.ac.uk, and we
shall attempt to put an alternative format.

The micrograph shows effect of image analysis on a sample of
consolidated kaolin. The analysis is automatic and delineates
regions of similar orientation.
We wish to encourage people to submit examples of their micrographs for display as future Micrographs of the Month.
The preferred method is to submit the micrograph in digital
form attached to an Email to geo.micro@uea.ac.uk
