The type of rock pictured is igneous rocks by origin.
Intrusive igneous rocks, formed beneath the Earth's surface through the slow cooling and solidification of magma, exhibit a coarse-grained texture due to the extended period for mineral growth.
Several common examples of these rocks include granite, gabbro, and diorite.
Granite, a prevalent intrusive rock, boasts a light-colored appearance and comprises quartz, feldspar, and mica.
This unique combination of minerals contributes to its durability and aesthetic appeal, making granite a popular choice in construction applications such as countertops and monuments.
Gabbro, another intrusive igneous rock, is typically dark-colored and consists mainly of plagioclase feldspar, pyroxene, and sometimes olivine.
It shares similarities with basalt, a fine-grained extrusive rock.
Gabbro's durability and suitability for construction materials have led to its use in projects ranging from buildings to harbor walls.
Diorite, with its medium-colored composition of plagioclase feldspar, hornblende, and biotite mica, is commonly found in various geological settings.
It serves practical purposes in the construction industry, contributing to the production of materials like road aggregate.
Without visual reference, pinpointing the specific type of intrusive igneous rock in an image can be challenging.
