Amir Akhavan, born 1964 in Germany, PhD in biology.

I am very interested in both chemistry and geology, and minerals to me are where these topics meet.

A few years ago I started a web site on quartz. My interest in that mineral is very broad, to me a chert is just as interesting as a gwindel. For some time all my collecting activities and trips had to do with filling the "virtual quartz museum" with photos, figures and computer renderings. During that time I have acquired a good knowledge about that mineral and how it behaves in different environments.

As a Mindat manager I work on all that is related to silica minerals and their varieties, as well as silicious rocks.

Other special interests: petrology, microscopy (thin sections), photography.
I love to field-collect and explore.

Concretion, Flint Run, Franklin Co., Ohio

Flint Run Ravine, Sharon Township, Franklin Co., Ohio, USA

A second photo from a bit of a distance. Big old 5' wide Ohio shale concretion hanging in the wall of Flint Run ravine in northern Franklin Co., Ohio. Notice the shale arched around this calcareous concretion. The calcareous concretions may contain a diversity of minerals filling interior septarian voids: among them, baryite, quartz, dolomite, calcite, and whewellite. Near these massive concretions are smaller sulfide concretions of pyrite and marcasite (shown in another photo from this location).
