Mistaken Point was so named because sailors found it a navigational hazard on the foggy tip of Newfoundland's Avalon Peninsula. The site is on Canada's Tentative List for proposed UNESCO World Heritage Sites. No-one can visit the fossil site without an official guide; collecting actual fossils may not be done.
The fossils are in Mistaken Point's tilted and faulted mudstone and sandstone. They are exposed, visible on the surface. They are part of the Ediacaran biota, the oldest complex (multicellular) life forms. The Ediacaran is the last period in the Proterozoic eon. They date to 579 to 542 million years ago, when all life was in the sea.
The Reserve is the only place in the world where you can see a 565-million-year-old sea floor which preserves the ecology of these ancient deep sea communities.
This lagerstätte includes over 30 types of ancient creatures, most of them extinct groups unknown in our modern world.
The creatures lived on the bottom of a deep ocean, below the depths that light could reach. What is now Newfoundland was then between latitudes 40°–65° South.
The imprints of the soft-bodied animals were preserved in place on the muddy sea floor when they were suddenly buried by repeated volcanic ash-falls. The ash (tuff) layers contain zircon, which makes it possible for geologists to accurately date the fossil layers by radiometric dating. Fossils of similar age are found in Russia and Australia, but the variety found at Mistaken Point make the site unique.
Period (geology)
A period in geology is a main subunit of an era.
Thus the Mesozoic era is divided into three periods: the Triassic, the Jurassic and the Cretaceous. These periods are then further subdivided into epochs.
Bismuth(III) chloride
Bismuth(III) chloride, also known as bismuth trichloride, is a chemical compound. Its chemical formula is BiCl. It has bismuth and chloride ions in it. The bismuth is in its +3 oxidation state.
Bismuth(III) chloride is a pale yellow solid. It reacts with water to make bismuth oxychloride and hydrochloric acid. It dissolves in acids like hydrochloric acid. It reacts with reducing agents to make bismuth metal.
It is made by reacting bismuth with chlorine. It can also be made by dissolving bismuth(III) oxide in hydrochloric acid. Bismuth can be dissolved in nitric acid to make bismuth(III) nitrate, which reacts with sodium chloride to make bismuth(III) chloride.
It is used as a catalyst in organic chemistry. It is a good source of bismuth and is used to make other bismuth compounds.
Bismuth(III) chloride can cause burns on skin because it makes hydrochloric acid when it reacts with water. It irritates the gastrointestinal tract.
Incheon
Incheon (officially, Incheon Metropolitan City) is a major port city in South Korea and famous for Incheon International Airport.
Incheon is 28 km from the nation’s capital, Seoul. It is at 126° 37´ east longitude and 37° 28´ north latitude, the same latitude as San Francisco, Washington, Madrid, and Teheran. Incheon is the third largest city in South Korea, after Seoul and Busan and 2.6 million people lives in Incheon (2009).
There are ten administrative districts in Incheon and it is divided into 8 wards ("gu") and 2 counties ("gun").
Incheon Subway and Seoul Metropolitan Subway is linked (line number 1) and it takes approximately an hour from Incheon subway station to Seoul Station.
The history of Incheon started from the Goguryeo Kingdom in 475 AD, under the reign of King Jangsu. Its original name was Michuhol and it changed several times and renamed to Incheon-gun in the 13th year of King Taejong’s reign during Joseon period. In 1949, after Korea`s 1945 liberation, Incheon City reorganized. It was finally renamed to Incheon Metropolitan City in 1995.
During the Korean War, there was the battle of Incheon led by an American general of UN Douglas MacArthur and the battle resulted in a decisive victory. It was also a strategic reversal in favor of the United Nations(UN). In a show of gratitude to the American soldier, Koreans in the late 1950s erected the bronze statue of MacArthur in a central park at Incheon that overlooks the sea area through which his troops came ashore.
Incheon is famous for 17th Asian Games,Incheon International Airport, Incheon Port, Songdo International City, Incheon Subway, and Munhak Worldcup Stadium are five major cites of Incheon.
Ganghwa-county (Ganghwa Island) is famous for dolmens registered as one of the World Heritages by UNESCO.
Hwamunseok mats are Incheon's famous local products, a figured mat. The beauty of these hand-woven mats has made them one of the most famous specialty products of Ganghwa-gun, and one of the most beloved traditional Korean crafts.
Wolmido was once a military base of Japanese Army during the Japanese colonial period and a outpost of the battle of Incheon. Nowadays, Wolmido is one of the most famous tourist spots near the Metropolitan area. Along the 1 km-long Wolmido Street of Culture, there are lots of beautiful cafes and restaurants. Wolmido is also famous for street performers, portrait artists and Wolmi Festival.
To become an international economic hub and a center of business and service industry of Asia, Incheon is developing free economic zone in the three regions of Songdo, Cheongra, and the island of Yeongjong. Incheon's Free Economic Zone, the first in Korea, was officially designated by the Korean government in August 2003 and it is planing to 2020.
Bismuth fluoride
Bismuth fluoride can mean either of these chemical compounds:
Bismuth(III) oxychloride
Bismuth(III) oxychloride is a chemical compound. Its chemical formula is BiOCl. It has bismuth, oxide, and chloride ions in it. The bismuth is in its +3 oxidation state.
Bismuth(III) oxychloride is a whitish solid. It is a weak oxidizing agent. It is somewhat shiny. It does not dissolve in water. It makes a very complicated molecule when it is heated.
It is made by reacting bismuth(III) chloride with water.
It is used in cosmetics as a pearlescent coating.
Don Poile
Donald B. Poile (born June 1, 1932 in Fort William, Ontario) is a retired professional ice hockey player who played 66 games in the National Hockey League with the Detroit Red Wings.
