ज्वालामुखी-कांच इसके अंग्रेजी अर्थ का उदाहरण

Apatite, sphene, zircon, micas and volcanic glass typically contain enough uranium to be useful in dating samples of relatively young age (Mesozoic and Cenozoic) and are the materials most useful for this technique.

Pyroxenes were named this way because of their presence in volcanic lavas, where they are sometimes seen as crystals embedded in volcanic glass; it was assumed they were impurities in the glass, hence the name "fire strangers".

The shells reflect one of the earliest major imports into the interior of northern Guatemala, and Richard Hansen believes they and similar exotic imports, such as jade and obsidian (a volcanic glass from which sharp tools could be fashioned), played an important role in the formation of an increasingly complex society.

Monte Arci was one of the most important Mediterranean centres for mining and processing of this volcanic glass in the area.

It can be defined as volcanic glass fibers or thin strands of volcanic glass.

Feldspar, amphiboles, pyroxenes, and volcanic glass are the principle donors of clay minerals.

The natural volcanic glass obsidian can achieve a nearly molecular edge (high achievable sharpness) and only requires Stone Age technology to work, but is so brittle that it cannot maintain that sharpness for very long.

Axiolitic texture results from spherulitic growth along fractures in volcanic glass, often from invasion of water.

Some fiamme are formed from flattened hot, relatively low viscosity, high porosity fragments of volcanic glass or pumice.

Photogrammetry organizations Pele's tears (closest Hawaiian translation: "nā waimaka o pele") are small pieces of solidified lava drops formed when airborne particles of molten material fuse into tearlike drops of volcanic glass.

Pele's tears are also found entangled within fine strands of volcanic glass known as Pele's hair and it was considered that they formed together under similar conditions.

The volcanic glass bubbles burst and are dispersed by the wind, showering flakes of glass downwind.
