Igneous Rocks:

* Granite: A common, coarse-grained igneous rock that often forms deep within the Earth's crust. Its high quartz and feldspar content makes it quite ductile at high temperatures.

* Gabbro: A dark-colored, coarse-grained igneous rock that is often found in oceanic crust. Its high mafic mineral content (pyroxene and olivine) contributes to its ductility.

* Diorite: An intermediate igneous rock with a composition between granite and gabbro. Its ductility is influenced by its mineral composition, temperature, and pressure.

Metamorphic Rocks:

* Schist: A metamorphic rock with a foliated texture, often formed from shale or other sedimentary rocks. Its high mica content and pressure-induced recrystallization make it ductile.

* Gneiss: A metamorphic rock with a banded texture, often formed from granite or other igneous rocks. Its layered structure and mineral composition make it ductile.

* Marble: A metamorphic rock formed from limestone or dolostone. While not as ductile as schist or gneiss, it can deform under high pressure.

Other:

* Salt: Salt is a relatively weak rock but can be very ductile under pressure. It often deforms through flowage, creating salt diapirs.

Factors Affecting Ductility:

* Temperature: Rocks become more ductile at higher temperatures.

* Pressure: Higher pressures can increase ductility.

* Mineral Composition: The type and abundance of minerals in a rock significantly influence its ductility.

* Strain Rate: Rocks deform more readily at slower strain rates.

Note:

* Ductility is a relative term. Even "ductile" rocks can behave in a brittle manner under certain conditions (low temperature, high strain rate).

* The specific behavior of a rock will depend on the combination of these factors.
