Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Artuqids
The Artuqid dynasty (alternatively Artukid, Ortoqid, or Ortokid; , pl. ; ; ) was a Turkoman dynasty originated from tribe that ruled in eastern Anatolia, Northern Syria and Northern Iraq in the eleventh through thirteenth centuries.

Artuk's sons and descendants ruled the three branches in the region: Sökmen's descendants ruled the region around Hasankeyf between 1102 and 1231; Ilghazi's branch ruled from Mardin and Mayyafariqin between 1106 and 1186 (until 1409 as vassals) and Aleppo from 1117–1128; and the Harput line starting in 1112 under the Sökmen branch, and was independent between 1185 and 1233.
