Igneous Rocks

 · Igneous rocks (from the Greek word for "fire") form when hot, molten rock (magma) crystallizes and solidifies. Magma originates deep within the Earth, near active plate boundaries or hot spots.

Characteristics of Igneous Rocks

Igneous rocks are very hard (harder than sedimentary rocks) and resistant to elevated temperature conditions. Resistance to extreme heat is understandable from the fact that these rocks are formed from the hot and molten magma (625-1200° C), which occur beneath the earth''s surface.

Igneous Rocks | National Geographic Society

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. ...

The Relationship Between Igneous Rocks & Tectonic Plates

Igneous rocks can also form where plates bump up against each other. Sometimes when tectonic plates converge they create an area where one tectonic plate is pushed under another plate. This area is referred to as a subduction zone. The subducting plate is pushed into the hotter, deeper layers of the Earth, where it melts.

Igneous Rocks | Earth Science

Igneous rocks form when molten material cools and hardens. They may form either below or above Earth''s surface. They make up most of the rocks on Earth. Most igneous rock is buried below the surface and covered with sedimentary rock, and so we do not often see just how much igneous rock there is on Earth. In some places, however, large areas ...

 · Abandoned mines and quarries are dangerous places! In a typical year, several people die in accidents that occur in abandoned mines across the United States. Some of these deaths can be prevented if citizens know the danger of these properties; if landowners make better efforts to warn and limit access; and, if governments have improved programs for reclaiming or regulating them.

The Quarry Story

Igneous rocks – A type of rock that forms from hot magma or lava that comes from deep within the earth. As it slowly cools it becomes rock such as granite, basalt, or gabbro. Metamorphic rocks - A type of rock that develops from the alteration of sedimentary, igneous, or other metamorphic rocks due to extreme heat and/or pressure.

Nearly 5,000 years after prehistoric engineers built the mysterious circle in the south of England, the rocks that make up Stonehenge continue to fascinate people around the world. Scientists have determined that the largest of Stonehenge''s sandstone blocks, each weighing about 25 tons, were hauled 30 kilometers (18.6 miles) from where they were quarried.

Geological landmarks

Igneous rocks can be identified by their characteristics which are hard, strong and have interlocking crystals. Their colour, crystal size and texture can vary. An igneous rocks colour is determined by the minerals that it contains, dark coloured rocks have more dark (mafic) minerals than light (felsic) minerals.
