2017-2-17 The basaltic magma started to crystallize around ∼1250–1200 ∘ C. Bubble initiation to growth in the fast ascending magma may have taken in ∼3 hr. The Vastan pumice thus serves as a pointer to active spreading centres and transport directions during the opening of the Arabian Sea and resultant submarine mafic volcanism.

2020-5-18 There are two types of pumice: acidic and basaltic (scoria). Acidic pumice (AP) has a density between 0.5 and 1 g/cm 3, while that of basaltic pumice (BP) is higher, 1.2–2 g/cm 3. BP has darker color and thicker bubble walls than AP. In Turkey, about 4 million metric tons of pumice is mined annually, which accounts for a quarter of world production . Pumice has a hardness value of about 6 in Mohs

2007-6-1 The basaltic pumice cone deposits of Quaternary age are located in the Cukurova region (Southern Turkey). There are estimated reserves of approximately 1000 million tonnes. The pumice comprises an average 85% volcanic glass and 15% phenocrystic feldspars, along with traces of spheroid hematite minerals, determined by microscopy.

2021-5-31 Born of Fire. These pumice were rounded not by any efforts of man but aerodynamically by nature on eruption. Formerly under enormous pressure, trapped gases in frothy molten lava globules, flung miles high, make bubbly escape, creating new-born foamy stones by fast-drying into rounded form by time they hit earth -- or almost dry, often flattening into eggs or oval bars or, very rare, pancakes.

Pumice is composed of highly microvesicular glass pyroclastic with very thin, translucent bubble walls of extrusive igneous rock. It is commonly,but not exclusively of silicic or felsic to intermediate in composition (e.g., rhyolitic, dacitic, andesite, pantellerite, phonolite, trachyte), but basaltic

Basalt is the most common rock on Earth’s surface. Specimens are black in color and weather to dark green or brown. Basalt is rich in iron and magnesium and is mainly composed of olivine, pyroxene, and plagioclase. Most specimens are compact, fine-grained, and glassy. They can also be porphyritic, with phenocrysts of olivine, augite, or ...
