Definition of silicify in English: silicifyverbsilicified, silicifying, silicifies sɪˈlɪsɪfʌɪsəˈlɪsəˌfaɪ [with object]Convert into or impregnate with silica. the calcareous skeleton has been silicified Example sentencesExamples - Bedding planes in the enclosing limestones do not bend around the nodules, and any brachiopods, corals, or other fossils that are in them have been silicified.
- The limestones, which have been silicified near the granodiorite contact, have in places been intensely metamorphosed into a typical contact-metasomatic assemblage.
- Morphologically, it is difficult to relate the silicified microbes to the unsilicified or partly silicified microbes.
- For most large deposits of agate or silicified wood, silica was derived from the decomposition of volcanic rocks.
- Where the Zeederbergs-Cheshire contact lacks ironstone horizons, the contact is variably sheared, and adjacent rocks are silicified and characterized by mostly oxidized sulphide impregnation.
- Highly silicified stalks to 10 cm in diameter have been found at this locality.
- In many places, the top of the ‘lower Gasconade’ is marked by a heavy chert zone comprising silicified algae and/or stromatolites.
- The nodules are approximately spherical in shape and have an exterior shell of rhyolite that is more silicified than the host rock.
- Mite wood borings in the Paleozoic are primarily known from coal ball permineralizations and silicified peat which was deposited in swampy environments.
- However, it has been pointed out that the presence of the articulamentum layer is often difficult to detect in the early fossils, since many Paleozoic polyplacophorans are silicified and incompletely preserved.
- Silica cells were silicified in the first year, and the frequency was not significantly different among the three leaf ages.
- Later, authigenic quartz was precipitated and carbonate phases were partly silicified.
- In the high - porosity laminae, individual silicified microbes remain clearly visible and their general morphology and size readily apparent.
- Trace amounts of iron oxide impart vibrant red, red-orange, orange, and yellow colors that sometimes contrast markedly with browns and blacks in these silicified trunks.
- The entire fragment is silicified and details of its skeletal structure have been destroyed.
- This highly silicified cycad contained bright red-orange to black, diamond-shaped leaf bases of chalcedony up to several centimeters across separated by zones of greenish-yellow chalcedony.
- They are largely silicified replacements of the once opaline skeletons, but details of their spicular and skeletal relationships are moderately well preserved.
- Cooccurring macrofossils include 18 species of agnostoid and polymeroid trilobites, some of which are partly silicified.
- The discovery that silicified trilobites could be dissolved out of limestone in dilute acid added more knowledge more quickly than years of patient preparation from crack-out specimens.
- Bryozoan and trilobite fragments, brachiopod spines, turrilepadid plates, and multiplacophoran spines are silicified.
