3D Igneous Rock Gallery

Put on your 3D glasses to see the rocks.

1. Granite is an intrusive igneous rock with phaneritic texture and felsic minerals.

 

 

2. Rhyolite is an extrusive igneous rock with aphanitic texture and felsic minerals.

 

 

3. Diorite is an intrusive igneous rock with phaneritic texture and intermediate minerals.

 

 

4. Andesite is an extrusive igneous rock with aphanitic texture and intermediate minerals.

 

 

5. Gabbro is an intrusive igneous rock with phaneritic texture and mafic minerals.

 

 

 

6. Basalt is an extrusive igneous rock with aphanitic texture and mafic minerals. Some basalts contain gas vesicles.

 

 

 

7. A porphyry is an igneous rock with mixed cooling history and texture. The coarse grains embedded in the fine grained matrix are called phenocrysts.

 

 

 

8. A pegmatite is an extrusive igneous rock with phaneritic texture and felsic minerals containing some very large crystals.

 

 

9. Obsidian is volcanic glass that forms when magma cools so quickly that it does not crystallize.
