Mother Lode
Mother lode is a principal vein or zone of gold or silver ore. The term is also used colloquially to refer to the real or imaginary origin of something valuable or in great abundance. Term The term probably came from a literal translation of the Spanish ''veta madre'', a term common in old Mexican mining. ''Veta madre,'' for instance, is the name given to an silver vein discovered in 1548 in Guanajuato, New Spain (modern-day Mexico). California Mother Lode In the United States, ''Mother Lode'' is most famously the name given to a long alignment of hard-rock gold deposits stretching northwest-southeast in the Sierra Nevada of California, bounded on the east by the Melones Fault Zone. It was discovered in the early 1850s, during the California gold rush. The California Mother Lode is a zone from wide and long, between Georgetown on the north and Mormon Bar on the south. The Mother Lode coincides with the suture line of a terrane, the Smartville Block. The zone contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Nugget
A gold nugget is a naturally occurring piece of Native metal, native gold. Watercourses often concentrate nuggets and finer gold in placer deposit, placers. Nuggets are recovered by placer mining, but they are also found in residual deposits where the gold-bearing vein (geology), veins or lodes are weathered. Nuggets are also found in the tailings piles of previous mining operations, especially those left by gold mining dredges. Formation Nuggets are gold fragments weathered out of an original lode. They often show signs of abrasive polishing by stream action, and sometimes still contain inclusions of quartz or other lode matrix material. A 2007 study on Australian nuggets ruled out speculative theories of supergene (geology), supergene formation via ''in-situ'' precipitation, cold welding of smaller particles, or bacterial concentration, since crystal structures of all of the nuggets examined proved they were originally formed at high temperature deep underground (i.e., they wer ...

Smartville Block
The Smartville Block, also called the Smartville Ophiolite, Smartville Complex, or Smartville Intrusive Complex, is a geologic terrane formed in the ocean from a volcanic island arc that was accreted onto the North American Plate during the late Jurassic (~160–150 million years ago). The collision created sufficient crustal heating to drive mineral-laden water up through numerous fissures along the contact zone. When these cooled, among the precipitating minerals was gold. Associated with the Western Metamorphic Belt of the Sierra Nevada foothills it extends from the central Sierra Nevada mountain range, due west, under a section of the Central Valley and California Coast Ranges, in northern California. The ophiolitic sequence found in this terrane is one of several major ophiolites found in California. Ophiolites are crustal and upper-mantle rocks from the ocean floor that have been moved on land. Ophiolites have been studied extensively regarding the movement of crustal rocks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Country
The Gold Country (also known as Mother Lode Country) is a historic region in the northern portion of the U.S. state of California, that is primarily on the western slope of the Sierra Nevada. It is famed for the mineral deposits and gold mines that attracted waves of immigrants, known as the 49ers, during the 1849 California gold rush. History When gold was first discovered in 1848, many people came from all over the world to find gold. The migration into California also brought diseases and violence. There were 500 mining camps of which 300 are still undocumented. There was $400 million in gold mined between 1849 and 1855. In 1942 most of the mines shut down due to World War II. The transportation in Gold Country grew rapidly due to the Gold Rush. The first railroad in California ran through Gold Country. There were 250 different stage coach companies formed by 1860.

Mega Man Legends
''Mega Man Legends'' is a sub-series in the ''Mega Man'' franchise. While the main series is known for its 2D side-scrolling platformer gameplay with story that is told through cutscenes, this series instead features 3D action-adventure gameplay and a more detailed story. Plot overview The games are set in the distant future; a time when the planet Earth is mostly ocean, leaving some islands left for civilization to prosper on. Based on the in-game dialogue, the series takes place at least in the 6th millennium. By this time frame, the original humans have been replaced by artificial lifeforms almost identical to them which can produce offspring with almost no effort. The player controls Mega Man Volnutt, a teenage digger and archaeologist of sorts who searches underground ruins mainly for Quantum Refractors, which are the civilization's primary source of energy. He was found as a baby on Nino Island at the bottom of the closed-off Nino Ruins and was raised by Professor Barrel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cheating In Video Games
Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay, usually in order to make the game easier. Cheats may be activated from within the game itself (a cheat code implemented by the original game developers), or created by third-party software (a game trainer or debugger) or hardware (a cheat cartridge). They can also be realized by exploiting software bugs. History The first cheat codes were put in place for play testing purposes. Playtesters had to rigorously test the mechanics of a game and introduced cheat codes to make this process easier. An early cheat code can be found in ''Manic Miner'', where typing "6031769" (based on Matthew Smith's driving license) enables the cheat mode. Within months of '' Wizardry: Proving Grounds of the Mad Overlord''s 1981 release, at least two commercial trainers appeared. 1983 advertisements for "The Great Escape Utility" for ''Castle Wolfenstein'' (1981) promised that th ...

Lode
In geology, a lode is a deposit of metalliferous ore that fills or is embedded in a fracture (or crack) in a rock formation or a vein of ore that is deposited or embedded between layers of rock. The current meaning (ore vein) dates from the 17th century, being an expansion of an earlier sense of a "channel, watercourse" in Late Middle English, which in turn is from the 11th-century meaning of ''lode'' as a "course, way". The generally accepted hydrothermal model of lode deposition posits that metals dissolved in hydrothermal solutions (hot spring fluids) deposit the gold or other metallic minerals inside the fissures in the pre-existing rocks. Lode deposits are distinguished primarily from placer deposits, where the ore has been eroded out from its original depositional environment and redeposited by sedimentation. A third process for ore deposition is as an evaporite. A stringer lode is one in which the rock is so permeated by small veinlets that rather than mining th ...

Bedrock
In geology, bedrock is solid rock that lies under loose material ( regolith) within the crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave it susceptible to erosion. Bedrock may also experience subsur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
