It seems like you're asking about igneous rocks which are formed from the cooling and solidification of magma or lava. The term "ingenious" doesn't exist in geology.

Here's the breakdown:

* Igneous rocks are one of the three main rock types, along with sedimentary and metamorphic rocks.

* Magma is molten rock found beneath the Earth's surface.

* Lava is magma that has erupted onto the Earth's surface.

Any rock type can be transformed into an igneous rock through the following processes:

1. Melting: Existing rocks, whether sedimentary, metamorphic, or even other igneous rocks, can melt under intense heat and pressure deep within the Earth.

2. Cooling and Solidification: The molten rock (magma or lava) then cools and solidifies, forming new igneous rocks.

Examples of how rocks are transformed into igneous rocks:

* Sedimentary rocks: Limestone, sandstone, and shale can melt and solidify into igneous rocks like granite.

* Metamorphic rocks: Marble, slate, and gneiss can melt and solidify into different types of igneous rocks.

* Other igneous rocks: Existing igneous rocks can be melted and re-solidified, forming new igneous rocks with different compositions and textures.

So, any rock type can be the source material for an igneous rock, but it's not a process of "changing" one type of rock into another. It's about melting and re-crystallization.
