Rai Stone
A rai stone ( yap, raay), or fei stone, is one of many large artifacts that were manufactured and treasured by the native inhabitants of the Yap islands in Micronesia. They are also known as Yapese stone money or similar names. The typical rai stone is carved out of crystalline limestone and is shaped as a disk with a hole in the center. The smallest may be in diameter. The largest extant stone is located on Rumung island, near the Riy village; it is in diameter and thick, and weighs . Rai stones were quarried on several of the Micronesian islands, mainly Palau, but briefly on Guam as well. The practice stopped in the early 20th century. Today there are around 6,000 large rai stones outstanding in the island, and several can be seen in museums around the world. The stones were highly valued by the Yapese, and used for important ceremonial gifts. The ownership of a large stone, which would be too difficult to move, was established by its history as recorded in oral tradi ...

Yap Stone Money
Yap ( yap, Waqaab) traditionally refers to an island group located in the Caroline Islands of the western Pacific Ocean, a part of Yap State. The name "Yap" in recent years has come to also refer to the state within the Federated States of Micronesia, inclusive of the Yap Main Islands and its various outer islands, the Yap Neighboring Islands. For specifying the island group, the name ''Yap Main Islands'' is most exact. Geography Yap is actually made up of four separate islands: Yap Proper (''Marbaaq''), Gagil-Tamil, Maap ( yap, Maap′), and Rumung. The four islands are separated by relatively narrow water features, and the islands are surrounded by a common coral reef. Gagil-Tamil was once connected to Yap Proper, but a canal, ''Tagireeng Canal'', less than 10 meters wide, was constructed that separated the two landmasses in 1901. Yap was formed from an uplift of the Philippine Sea Plate, and is referred to as a "high" island as opposed to atolls. The land is mostly rolling hil ...

Anagumang
Anagumang was a legendary Yapese navigator who led an expedition in rafts and canoes five or six hundred years ago. On this expedition he discovered the islands of Palau and brought stones from Palau to Yap. Expedition Anagumang hired seven men with him for his journey, with the help of his mother, Le-gerem. Stones First Anagumang ordered his men to cut stone into the shape of fish, then a crescent moon, and then a full moon with a hole in it for transport. He fashioned other stones so they could be slipped onto a trunk of a betel-nut tree. The stones came in different sizes. The smallest were 7-8 centimeters long, and the longest were 3.6 meters in diameter and 0.5 meters thick and weighed four tons. Currency These stones were called "Rai stones A rai stone ( yap, raay), or fei stone, is one of many large artifacts that were manufactured and treasured by the native inhabitants of the Yap islands in Micronesia.

Stone Money Of Uap, 1903, Jayne, String Figures, P
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existing rocks. M ...

Babeldaob
Babeldaob (also Babelthuap) is the largest island in the island nation of the Republic of Palau. It is in the western Caroline Islands, and the second largest island (after Guam) in the Micronesia region of Oceania. Palau's capital, Ngerulmud, is located on Babeldaob, in Melekeok State. Babeldaob is one of the most underdeveloped populated islands in the Pacific Ocean. The area of Babeldaob, , makes up over 70% of the land area of the entire Republic of Palau. It has about 30% of the country's population, with about 6,000 people living on it. Geography Babeldaob is located northeast of Koror Island, and its northern portion contains the site of the new national capital, Ngerulmud. The southern end of the island is in Airai State, Palau's second-most populous state. The Airai Airport on the island is the nation's principal airport. The Koror-Babeldaob Bridge links Babeldaob Island at Airai to Koror Island. Unlike most of the islands of Palau, Babeldaob is mountainous. It conta ...

Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or Dolomite (mineral), dolomite. Marble is typically not Foliation (geology), foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for Marble sculpture, sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; Robert S. P. Beekes, R. S. P. Beekes has suggested that a "Pre-Greek origin is probable". This Stem (linguistics), stem is also the ancestor of the English language, English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French language, French , most other European languages (with words like "marmoreal") more closely resemb ...

Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...
