Flint is a hard, sedimentarycryptocrystalline form of the mineralquartz, categorized as a variety of chert. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones. Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. From a petrological point of view, "flint" refers specifically to the form of chert which occurs in chalk or marly limestone. Similarly, "common chert" (sometimes referred to simply as "chert") occurs in limestone.
The exact mode of formation of flint is not yet clear but it is thought that it occurs as a result of chemical changes in compressed sedimentary rock formations, during the process of diagenesis. One hypothesis is that a gelatinous material fills cavities in the sediment, such as holes bored by crustaceans or molluscs and that this becomes silicified. This hypothesis certainly explains the complex shapes of flint nodules that are found. The source of dissolved silica in the porous media could be the spicules of silicious sponges. Certain types of flint, such as that from the south coast of England, contain trapped fossilised marine flora. Pieces of coral and vegetation have been found preserved like amber inside the flint. Thin slices of the stone often reveal this effect.
Baggage cannot be checked at this location; however, up to two suitcases in addition to any "personal items" such as briefcases, purses, laptop bags, and infant equipment are allowed on board as carry-ons.
This is at least the fourth station along the Grand Trunk Western Railroad (GTW) line through Flint. The railroad arrived from Port Huron in 1871 and originally a wooden structure served as the passenger station. A 1905 stone and brick station was moved to Muskegon in 1927. The third GTW depot, located at 120 East 14th Street, was used by Amtrak until 1989 and demolished thereafter. The current station on Dort Highway provides easy access to I-69.
From its first known general election in 1542 until 1918, the constituency consisted of a number of boroughs within the historic county of Flintshire in north-east Wales. The seat should not be confused with the county constituency of Flintshire, which existed from the 16th century until 1950.
After 1918 Flintshire was represented in Parliament by the single member county constituency, which included all the boroughs formerly in the Flint District of Boroughs.
On the basis of information from several volumes of the History of Parliament, it is apparent that the history of the borough representation of Wales and Monmouthshire is more complicated than that of the English boroughs.
