Overview:Basanite is an igneous, volcanic (extrusive) rock, of felsic composition, with aphanitic to porphyritic texture. Mineral assembly is usually abundant feldspathoids and plagioclase, and lesser alkali feldspar. Pyroxenes (clinopyroxenes) and olivines are common accessory minerals. Most basanite is produced in the same manner as basalt. When divergent plate boundaries are pulled apart and erupt on the oceans floor basanite is a by- product of this procedure. Hot basanite that comes into contact with the water quickly cools and it forms into the dark black to dark gray colored rock.With oceanic fissure eruptions which are hotspots, eruptions continually occur and basanite continually piles up from the ruptures with basalt. This process continues until an island is formed. This is how the island state of Hawaii was created.

Usage: Electromagnetic and environmental pollution, radiation, stress, prolonged illness or hospitalization, circulation,

digestive and sexual organs, balancing mineral content of the body.A black flinty jasper used for estimating the purity of precious metal alloys.

In addition to carrying the generic properties of Jasper,

Black Jasper or Basanite is a useful scrying stone that

takes you deep into an altered state of consciousness

and brings about prophetic dreams and visions. It can

call up your power animal and has strong links to the Black Panther shamanic line.


Basanites occur both on continents and on ocean islands. Also in Poland, USA and Spain.
