What mountain ranges are made from igneous rock?

I don't know exactly what you mean.

If you are asking about specific mountain ranges, some are:

The Organ Mountains in Brazil

Some of the Rocky Mountains in the West US

If you are talking in general, the mountain ranges made of igneous rocks are the ones formed from volcanoes. For example: most of the mountains in Hawaii are made of igneous rock because the island themselves are formed by volcanoes.
