CFC - Clay Database - Tabular Display (Condensed)

This is a condensed tabular display of the data in Clay Database. It is condensed in the sense that it contains only a subset of the full set of fields in the database that are apt to be of interest to users seeking a general view of the data for multiple clay specimens. For a display presenting the full set of fields for a single clay specimen users can go to Record Display (see below). The NAA data for the clay specimens are presented separately on the CFC - NAA Data page.

Users can sort in ascending or descending numerical or alphabetical order on the Clay Number, Comune, Provincia, Regione, Date Acquired or Geologic Origin column by clicking on the column header. They can filter the dataset on the basis of Comune, Provincia, Regione or Geologic Origin by clicking on one of the values appearing in the appropriate scroll-down menu in the set of menus located immediately above the table and then clicking the Apply button situated immediately to the right of these. They can filter by two or more values by holding down the Control key, clicking on each of the desired values in the scroll-down menu and then clicking the Apply button. They can return the table to its default arrangement after sorting or filtering by clicking the Reset button.

Clicking on the content in a cell in the Clay Number column opens the display for that clay specimen in Record Display. Clicking on the content in a cell in the Comune, Provincia, Region, Date of Acquisition or Geologic Origin column generates a list of all of the clay specimens that have the same value as the one that appears in that cell. Clicking on any of the items in this list opens the record for the associated clay specimen in Record Display. To return from Record Display to Tabular Display (Condensed) users should employ the Back arrow.

Record Display presents the full set of fields for a single clay specimen arranged by subject in groups and sub-groups. (Fields that are empty for that specimen, however, do not appear in the display.) All of the groups and sub-groups other than the Provenience group that appears at the top of the record are shown in a collapsed view. This can be expanded to show the fields contained in the group/sub-group by clicking on the group/sub-group heading. The thumbnails of photomicrographs and diffractograms that appear in the Texture and Mineralogical Composition sub-groups for many of the specimens can be expanded to a full-size image by clicking on the thumbnail. The full-size image can be restored to thumbnail size by clicking on the X that appears at its lower right corner.

Record Display does not permit users to step directly from the record for one clay specimen to that of another. To do this users should use the Back arrow to return to Tabular Display (Condensed) and then click on the cell in the Clay Number column for the desired clay specimen.

The CFC - Products - Data page contains a link to a downloadable spreadsheet that contains all of the data included in this database other than the images.
