Good question! According to Dana's Manual of Mineral Science (The Bible of minerals, in a way) a mineral must be solid. So, lava, which is not solid, is not a mineral. Once lava hardens into a solid, it becomes a rock made of different types of minerals.

There is a variety because of the origin of the lava itself. Some lava originates at a spreading ridge, other types at a subduction zone. All minerals can potentially be present in lava.

But in actuality, lava is more like a soup containing the ingredients for minerals along with already solidified minerals.The mineral composition of solidified lava will vary greatly depending on the source of the molten material, but common minerals present would be quartz, feldspars, olivine, pyroxene, biotite and muscovite micas, amphibole, and hornblende.

What is melted rock?
Melted rock is that hasn't surfaced is "Magma".If the melted rock already has surfaced, it is called "Lava".
What is hardened lava called?

Type of rocked formed when lave or magma cools?
A rock that is formed when magma cools is called a igneous rock.
Is lava a plasma?
Magma is not plasma since plasma is neither solid ,liquid or gas while magma is always solid when cool and liquid when hot.
What is the chemical makeup of a rock?
The rocks you see around you - the mountains, canyons & riverbeds, are all made of minerals. A rock is made up of 2 or more minerals. Think of a chocolate chip cookie as a rock. The cookie is made of flour, butter, sugar & chocolate. The cookie is like a rock and the flour, butter, sugar & chocolate are like minerals. You need minerals to make rocks, but you don't need rocks to make minerals. All rocks are made of minerals.
How can rock minerals form?
Rock minerals form from lava, magma or solutions.
Is hardened lava a mineral?
Hardened lava is considered igneous rock, composed of minerals.
What happened to lava when it cools?
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
Minerals in rock near a volcano recrystallize as lava covers the area--the minerals change due to the lava's?
The minerals in the country rock might change due to the effects of the heat in a process known as contact metamorphism.
What is the substance called that reaches earths surface and is made up of molten rock gases and minerals?
Lava.
How are minerals formed from magma and lava?
'fraid not. some minerals form from magma, which is hot, liquid rock material INSIDE Earth's surface. Not on Earth's surface.
An igneous rock with very small minerals crystal most likely formed from?
lava
How did the lava cool from hot lava to hard rock?
The minerals in magma form crystals when solidifying, giving igneous rocks their characteristic hardness.
What does pumice mean for rocks and minerals?
Pumice is an extrusive igneous rock which forms when the lava is very frothy from a lot of gas exsoliving out of the lava, it is sort of like an extrime vesicular rock.
What is formed by magma cooling?
Intrusive igneous rock is formed when magma or lava cools quickly.
What type of rock do all rocks start as?
they r pressed together from smaller particles
Is a rock with visible layers and no minerals likely to have formed lava hardening on Earth's surface?
yes
