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.

Tetrahedrite : Cu6(Cu4X2)Sb4S13, Chalcopyrite : CuFeS2, Siderite : FeCO3, Quartz : SiO2

Dimensions: 6.7 cm x 4.3 cm x 3.4 cm

6.7 x 4.3 x 3.4 cm. Tetrahedrite is rare from the historical mines at Neudorf, renowned for world-class galena, siderite and bournonite specimens. Textbook sharp metallic-gray tetrahedral crystals, to 4 mm, are aesthetically clustered in vugs in the sculptural sparkly quartz crystal matrix. Golden chalcopyrite and tan siderite rhombs are classic and excellent accessories to this rare combination. This exceptional old-time specimen has a fine provenance: The antique tetrahedrite was once in the collection of Colonel Joseph Neeld, 1789-1856 (# 1775) and was found before 1835. He was a Member of Parliament of the United Kingdom and a Colonel in the Royal Army. This collection, long forgotten and lost track of, resurfaced in England in the early 1980s and was purchased by Richard Barstow (no Neeld labels survived). It also comes with a century-old (late 1800s/early 1900s) torn and faded Ward's label, indicating that the piece was probably deaccessed from the Neeld Collection at an earlier date. Ex Kay Robertson Collection # 8846 and acquired in October, 1979 from Brian Lloyd. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). The Neudorf mines closed in 1903.
