What is Basalt? Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.It has a composition similar to gabbro.The difference between basalt and gabbro is that …
The Bateman project is an underground gold development in Ontario, Canada. It is owned by Battle North Gold, a Canadian gold miner.

Greenstone belts are interpreted as ancient volcano-sedimentary basins that are sandwiched between granitic rocks. These belts occur on most continents within cratons – fragments of old continents that have been stable for a long time and are Archean in age, i.e., 2.5-4.0 billion of years (Figure 1). They have undergone recrystallization at ...

Basalt is known for its dark color, typically ranging from black to dark gray, and its fine-grained texture. It is composed mostly of minerals such as pyroxene, plagioclase feldspar, and sometimes olivine. Basalt can have a range of compositions, but it is typically rich in iron and magnesium, and low in silica.
