Miargyrite

Formula:
AgSbS
 
2
System:MonoclinicColour:Black with dark red ...
Hardness:
Name:From Greek "meion" (less) and "argyros" (silver), for it contains less silver than pyrargyrite which it was often mistaken for.
Dimorph of:Cuboargyrite


The monoclinic dimorph of Cuboargyrite.

Black blocky often striated xls with dark red internal reflections to a cm. The crystals are difficult to orient and often form balls to a few cm.

About Crystal Atlas

You may need to scroll this box using your mouse to view the full instructions.

The mindat.org Crystal Atlas allows you to view a selection of crystal drawings of real and idealised crystal forms for this mineral and, in certain cases, 3d rotating crystal objects. You need Java to see these. You can download Java for free - click here to download Java

The 3d models and java code are kindly provided by www.smorf.nl. You can control the movement of the models by holding down the left mouse-button over the 3d model and moving your mouse. Keyboard controls are:

: default positions
t/T: decrease/increase transparency x/X: next/previous texture
b/B: next/previous background w: toggle wireframe
s: toggle sticks m: toggle miller indices
k: toggle crystallographic axes =/-: zoom in/out
r: stop/start rotation 1/2/3


Note: You will not be able to switch between different crystal models using the Opera 8.5x web browser due to a bug in Opera - you need to use either Firefox or Internet Explorer 6/7 or Opera 9.
