Formation (stratigraphy)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Period (geology)
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Eucommia
''Eucommia'' is a genus of small trees now native to China, with a fossil record that shows a much wider distribution. The single living species, ''Eucommia ulmoides'', is near threatened in the wild, but is widely cultivated in China for its bark, and is highly valued in herbology such as traditional Chinese medicine. Description Modern ''Eucommia'' trees grow to about 15 m tall. The leaves are deciduous, arranged alternately, simple ovate with an acuminate tip, long, and with a serrated margin. If a leaf is torn across, strands of latex exude from the leaf veins and solidify into rubber and hold the two parts of the leaf together. It flowers from March to May with the flowers being inconspicuous, small, and greenish. The fruits ripen between June and November and are a winged samara with one seed, very similar to an elm samara in appearance. The modern fruits are long and broad, while fruits of the extinct species range up to long. ''Eucommia'' is dioecious, with sepa ...

Cissus
''Cissus'' is a genus of approximately 350 species of lianas (Woody plant, woody vines) in the grape family (Vitaceae). They have a cosmopolitan distribution, though the majority are to be found in the tropics. Uses Medicinal ''Cissus quadrangularis'' has been evaluated for potential medical uses. As a source of carotenoids, triterpenoids and ascorbic acid the extracts may have potential for medical effects, including "gastroprotective activity" and benefits in terms of "lipid metabolism and oxidative stress". ''Cissus quinquangularis'' was used by the Maasai people of Kenya to relieve some of the symptoms of malaria. Ornamental ''Cissus antarctica'', ''Cissus alata'' and ''Cissus incisa'' are cultivated as garden plants, depending on area of the world. Succulent members of the genus such as ''Cissus quadrangularis'' are also found in the nursery trade but tend to be frost tender and are thus not widely cultivated.

Cercidiphyllum
''Cercidiphyllum'' is a genus containing two species of plants, both commonly called katsura. They are the sole members of the monotypic family Cercidiphyllaceae. The genus is native to Japan and China and unrelated to ''Cercis'' (redbuds). Description The type species, ''Cercidiphyllum japonicum'', can reach in height, and is one of the largest hardwoods in Asia. The other species, ''Cercidiphyllum magnificum'', is much smaller, rarely reaching over in height. ''Cercidiphyllum'' produces spurs along its twigs. These are short stems with closely spaced leaves. The foliage is dimorphic. According to a recent description "short shoots bear broadly cordate or reniform, palmately veined leaves with crenate margins; long shoots bear elliptic to broadly ovate leaves with entire or finely serrate margins."Peter K. Endress. 1993. "Cercidiphyllaceae" pages 250-252. In: Klaus Kubitzki (editor). ''The Families and Genera of Vascular Plants''. volume II. Springer-Verlag: Berlin; Heidelber ...

Carya Antiquorum
Hickory is a common name for trees composing the genus ''Carya'', which includes around 18 species. Five or six species are native to China, Indochina, and India ( Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada. A number of hickory species are used for products like edible nuts or wood. Hickories are temperate forest trees with pinnately compound leaves and large nuts. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, long and diameter, enclosed in a four- valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (''C. illinoinensis''); it is divided into two halves, which split apart when the seed germinates. Etymology The name "hickory" derives from a Native American word in an Algonquian language (perhaps Powhatan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betula Stevensoni
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech-oak family Fagaceae. The genus ''Betula'' contains 30 to 60 taxonomy of Betula, known taxa of which 11 are on the IUCN Red List, IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaf, leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara (fruit), samara, although the wings may be obscure in some species. They differ from the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ampelopsis
''Ampelopsis'', commonly known as peppervine or porcelainberry, is a genus of climbing shrubs, in the grape family Vitaceae. The name is derived from the grc, ἅμπελος (''ampelos''), which means "vine". The genus was named in 1803. It is disjunctly distributed in eastern Asia and eastern North America extending to Mexico. ''Ampelopsis'' is primarily found in mountainous regions in temperate zones with some species in montane forests at mid-altitudes in subtropical to tropical regions. ''Ampelopsis glandulosa'' is a popular garden plant and an invasive weed. Species ''Plants of the World Online'' currently includes: # ''Ampelopsis aconitifolia'' Bunge # '' Ampelopsis acutidentata'' W.T.Wang # ''Ampelopsis bodinieri'' (H.Lév. & Vaniot) Rehder # '' Ampelopsis chondisensis'' (Vassilcz. & V.N.Vassil.)

Curculio
''Curculio'' is a genus of weevils belonging the family Curculionidae and subfamily Curculioninae. Members of the genus are commonly referred to as acorn weevils or nut weevils as they infest the seeds of trees such as oaks and hickories. The adult female weevil bores a tiny hole in the immature nut to lay her eggs, which then hatch into legless grubs. In autumn, the grubs bore holes through the shells from the inside to emerge into the soil where they may live for a year or two before maturing into adults. Species Species of ''Curculio'' include: See also * ''Curculigo ''Curculigo'' is a flowering plant genus in the family Hypoxidaceae, first described in 1788. It is widespread across tropical regions of Asia, Africa, Australia, and the Americas. Curculin is a sweet protein that was discovered and isolated in ...''
