Fast access:

Shows all (or last 20, 10, 5 added) thumbnails without any query (download time depends on the number of images held).








To search the database do the following:

Limit the category by an expression given in the pull-down-menu or leave it blank if you don't want to limit the category.

Click the checkbox of the category which should be listed in the result table (only two categories are listed in the result table). If you don't sort any category, the results will be sorted by default by "natural / experimental" and "scale" category.

  primary / secondary search description  
  rock type      
  overprinted structure      

Example: You are looking for images of natural mesoscale Structures in magmatic rocks and you want the result table sorted by primary and secondary structures (like primary folds, secondary faults ...). Limit the "natural / experimental" category to natural, limit the "scale" category to meso, limit the "rock type" category to magmatic and click the checkboxes of the "primary / secondary" category and "structure" category.

Additionally you can search the description by typing any string (Example: search description = tectonic.  The result is limited to images containing the word "tectonic" in the description).

You can specify your selection in the category "structure" by clicking on the Specify button (Example: isoclinal folds).
