Basalt extrusive Pahoehoe is a feature that forms on the surface of very fluid basalt flows. Much like the skin on a bowl of tomato soup – the surface in contact with the air begins to crystallize, while the fluid lava below continues to flow. This drags the upper, still plastic, surface into a .

 · (B) Lava eruption – A slight increase in the microwave power may elevate the pressure inside the stone and induce cracks from which the lava erupts and flows out, onto the basalt surface.

It will not be porous like lava rocks are. It may have small round structures like tiny balls showing on the broken surface. These are called chondrules and many stone meteorites (the chondrites) will have them. But it will not have holes inside if it is a meteorite. Most stone meteorites will not have shiny crystals in .

The terms lava stone and lava rock are more used by marketers than geologists, who would likely say "volcanic rock" (because lava is a molten liquid and rock is solid). "Lava stone" may describe anything from a friable silicic pumice to solid mafic flow basalt, and is sometimes used to describe rocks that were never lava, but look as if they were (such as sedimentary limestone with ...

Basalt is the most common rock on Earth's surface. Specimens are black in color and weather to dark green or brown. Basalt is rich in iron and magnesium and is mainly composed of olivine, pyroxene, and plagioclase. Most specimens are compact, finegrained, and glassy. They can also be porphyritic, with phenocrysts of olivine, augite, or ...

Lava Flows and Vesicular Basalts. Some newly erupted lava flows contain abundant dissolved gas. The gas bubbles in the flow move upwards towards the surface in an attempt to escape while the lava is still molten. However, once the lava starts to solidify, the bubbles are trapped in the rock. These trapped gas bubbles are known as vesicles.

Basalt porphyrite from the Isle of Mull, Scotland with many plagioclase phenocrysts. The rock is 8 cm in length. Porphyritic basaltic rock from Tenerife. Phenocrysts are plagioclase (white) and augite (black). Width of sample 14 cm. Magnetite crystals are always microscopic in basalt, but sometimes they form black stripes in lightcolored sand.
