Luster means that something has a shiny or glossy surface. Basalt is a rock that does not have a luster at all.
On a fractured surface, no. If polished, yes.
No, basalt is usually rough and pitted.
metallic
== == Some basalts may be older than some sandstones, but ages of sandstones and basalts vary tremendously. Some sandstones are therefore older than some basalts. Oceanic basalts are rarely over 200 million years in age.
Basalt does not have cleavage, it has fracture.
Basalts and Andesites
Luster of tin
Graphite is black and posseses dull appearance

flood basalts and volcanoes
Flood basalts build volcanic cones because flood basalts are believed to originate when the head of a mantle hotspot first arrives beneath the base of a plate. Because of this, they are unable to build volcanic cones.
A factor that determines crystal size in igneous rocks is the speed in which the lava/ magma crystallised or froze. As pillow basalts form at mid ocean ridges where magma is erupted into direct contact with the cold sea water the crystals form very fast and are therefore small. Other basalts erupted on land still have relatively small crystals and crystallised relatively fast but overall slower then pillow basalts.
