Atlas of sediments and sedimentary structures

Continually under construction!

Scroll down to access image categories. There are 900 images so far; more to come.

Over the years I have collected 1000s of geological images: Black and white prints from negatives (does anyone remember these?), that morphed to 35mm colour slides, and thence to various digital formats. I have displayed some of the better images here – better in the sense of what they convey scientifically, and their aesthetic appeal. They are organised according to broad environmental categories, and each category includes modern analogues and ancient examples. Each has a brief explanation (that tends to be more technical than my other posts).

The Atlas is a living document – I will add (or delete) images as they come to hand.

Feel free to use these images in your school-university projects, blogs, or whatever takes your fancy, BUT they are NOT to be used for remunerative or commercial gain without permission.  I hope students of geology – earth sciences will find them useful.

The Atlases, as are all blogs, are a publication. If you use the images, please acknowledge their source as indicated below (it is the polite, and professional thing to do).  I retain copyright of all images presented herein; there are a few exception and these are indicated in the captions as image credit.
