How to use the mindat.org media viewer

Click/touch this help panel to close it.

Welcome to the mindat.org media viewer. Here is a quick guide to some of the options available to you. Different controls are available depending on the type of media being shown (photo, video, animation, 3d image)

Controls - all media types

Zoom in and out of media using your mousewheel or with a two-finger 'resize' action on a touch device.

Use the mouse or your finger to drag the image or the view area of the image around the screen.

< and > at the left and right hand side of the screen move forwards and backwards for the other images associated with the media you selected. Usually this is for further photos of the same specimen. Keyboard shortcuts: use the left and right arrow keys.

> in the bottom center, raises the information box giving details and further options for the media, < at the top of this box then hides it. Keyboard shortcuts: use the up and down arrow keys.

? opens this help window. Keyboard shortcuts: use the H key or the ? key.

Other keyboard shortcuts:

1Fit image to screen
2Fill screen with image
5Display at full resolution
<Make background darker
>Make background lighter
spaceHide/dim titles and buttons

Controls - Video

Video files have a standard set of video controls: - Reset to start, - Skip back, - Play, - Pause, - Skip forwards. Keyboard shortcuts: You can stop/start video play with the P key.

Controls - Animation (Spin Rotation)

Animation (usually 360 degree spin rotations) have their own controls: - enable spin mode. Note that while images are loading this option will not be available but will be automatically activated when the animation has loaded. Once active you can spin the image/change the animation by moving your mouse or finger on the image left/right or by pressing the [ or ] keys.

The button switches to move mode so that you can use your mouse/fingers to move the image around the screen as with other media types.

The button, or the P key will start playing the animation directly, you can interrupt this by using the mouse or finger on the image to regain manual movement control.

Controls - 3D Stereoscopic images

Stereoscopic 3D image viewing requires a suitable 3D television or monitor correctly configured for your computer. Passive 3D systems such as LG 3DTVs are the easiest to configure for this.

To enable/disable 3D stereo display of a compatible stereo pair image press the 3 key. If the left/right images are reversed on your display (this often happens in full-screen mode) press the 4 key to reverse them.

Copyright © photo by and specimen in the collection of Charles Creekmur  - This image is copyrighted. Unauthorized reproduction prohibited.

A single crystal of brown kimzeyite resting between cleaved masses of pink eudialyte in a carbonitite matrix consisting of calcite and aegirine from Magnet Cove. This specimen was collected in the company of Lawton Kimzey (brother of Joe Kimzey)of Magnet Cove, Arkansas in the mid 1950's. Overall size of specimen is 18 pounds and the field of view is about 1 1/2 inches. Collection of and photo by Charles Creekmur.

I cannot see any isometric crystal on this picture.

My knowledge about Kimzeyite from Magnet Cove is different. Am I wrong?

Maybe those broken pinkish sections are distorted kimzeyite crystals and the black crystals are aegerine.

It appears they are describing the brown crystal at the top center of the photo

Exactly. Upper center, but it looks like 2 or 3 tiny dark brown kimzeyites grown together, hence the aparent un-isometric elongation.

The photo is very badly and inadequately described and should be sent to user only until it is done correctly.

Actually, I was in the company of Joe Kimzeys brother, Lawton when we collected this specimen in the mid 1950's so I am pretty sure the identification is correct. As you probably know, Joe was connected with the state geology bureau and owned the land that the good magnetite was found on. Lawton had a house there in the Cove made out of native rock with a wide band of syenite lining the top layer just under the roof line. The exposed face of the syenite blocks was a thin veneer of sodalite from the Diamond Joe Quarry. Pretty impressive to see a wide blue band ringing the house
