  2. Engineered stone - Wikipedia

    en.wikipedia.org/wiki/Engineered_stone

    Engineered stone. Engineered stone is a composite material made of crushed stone bound together by an adhesive to create a solid surface. The adhesive is most commonly polymer resin, with some newer versions using cement mix. This category includes engineered quartz (SiO 2), polymer concrete and engineered marble stone. [1]

  3. Shocked quartz - Wikipedia

    en.wikipedia.org/wiki/Shocked_quartz

    Shocked quartz is a form of quartz that has a microscopic structure that is different from normal quartz. Under intense pressure (but limited temperature), the crystalline structure of quartz is deformed along planes inside the crystal. These planes, which show up as lines under a microscope, are called planar deformation features (PDFs), or ...

  4. Countertop - Wikipedia

    en.wikipedia.org/wiki/Countertop

    Countertop. A countertop, also counter top, counter, benchtop, worktop (British English) or kitchen bench (Australian or New Zealand English), bunker (Scottish English) is a raised, firm, flat, and horizontal surface. They are built for work in kitchens or other food preparation areas, bathrooms or lavatories, and workrooms in general.

  5. Granite - Wikipedia

    en.wikipedia.org/wiki/Granite

    Granite (/ ˈɡrænɪt / GRAN-it) is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.

  6. Sinkhole - Wikipedia

    en.wikipedia.org/wiki/Sinkhole

    Sinkhole. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet. [1][2][3][4] A ...

  7. Cuban underwater formation - Wikipedia

    Hypothetical ruins. Public access. Yes. The Cuban underwater formation is a site thought to be a submerged granite structural complex off the coast of the Guanahacabibes Peninsula in the Pinar del Río Province of Cuba. [1][2][3]

  8. Dendrite (crystal) - Wikipedia

    en.wikipedia.org/wiki/Dendrite_(crystal)

    A crystal dendrite is a crystal that develops with a typical multi-branching form, resembling a fractal. The name comes from the Ancient Greek word δένδρον (déndron), which means "tree" [citation needed], since the crystal's structure resembles that of a tree. These crystals can be synthesised by using a supercooled pure liquid, however ...

  9. Quartz monzonite - Wikipedia

    en.wikipedia.org/wiki/Quartz_monzonite

    Quartz monzonite. Quartz monzonite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase.
