Basalt - University of Auckland

Basalt. Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances. It is also found as intrusive dikes and sills.

Silica dust Cancer Council

Silica dust (crystalline silica) is found in some stone, rock, sand, gravel and clay. The most common form is quartz. Silica dust can also be found in the following products: bricks; tiles; concrete; some plastic material. When these materials are worked on, silica is released as a fine dust known as respirable crystalline silica or silica dust.

Basalt - Wikipedia

Basalt is an aphanitic (fine-grained) igneous rock that is relatively low in silica and alkali metals.Of its total content of quartz, feldspar, and feldspathoid (QAPF), less than 10% by volume is feldspathoid and less than 20% is quartz, with plagioclase making up at least 65% of its feldspar content. This places basalt in the basalt/andesite field of the QAPF diagram.

RESPIRABLE CRYSTALLINE SILICA: THE FACTS

Often referred to as ‘silica’, silicon dioxide chemically comprises a silicon atom bonded with two oxygen atoms. It can exist either in the form of a crystal, where the atoms are arranged in a regular lattice structure, or in an unstructured amorphous form. The crystalline forms of silica are much more hazardous than the amorphous forms.

Basalt is dark, fine-grained and often vesicular (having gas pockets). The pockets may be filled with secondary minerals, e.g. quartz, zeolite minerals, calcite, opal, etc. and then it is called amygdaloidal (a-mig-duh-loy-dal) basalt. The name may have originated with Pliny who used the Ethiopian word basal for iron-bearing rocks. (*) Basalt ...

What Colour is basalt rock? - findanyanswer

Basalt is a hard, black extrusive igneous rock. Extrusive means it comes mainly from volcanic eruptions. It has a low silica content which enables this lava to flow quickly and allows volcanic gases to escape without explosive events. It is a fine grained rock and is the most common rock type in the Earth's crust.
