The Important Role of Underground Metal Detector in Archeolo

Metal detectors can detect not only arms, but also can detect coins, keys and other metal objects.
In Battlefield Archaeology, most exhibits are metals, such as guns warheads, cartridges, bullets, artillery and shells, shrapnel and / or swords, etc., depending on the specific battle took place which exhibits historical period. Therefore, it is the most important tool Battlefield archaeologist.
For decades, as was rightly considered to be the Tomb of the "weapon", metal detector has been battered by criticism. Until 1983, Richard Fox and later Douglas Scott (Douglas Scott) through the Little Bighorn battlefield proved, through the system of metal detection surveys, archaeological decades of hard work in a very short period of time completed within. According to their estimates, the metal detector at the Little Bighorn battlefield who uncovered 5,000 pieces of ancient artifacts in the traditional way may only find one of the 10 or so.
Today, skilled staff with metal detector by an archaeologist and heritage conservation work in the archaeological field plays an important role in conservation is responsible for accurately recording the location of artifacts found, and a "package, as well as labeling Mark. " In other words, each piece of ancient artifacts have been packaged up, labeled and put it out when digging the hole drilled in order to remove it before for future research to identify its precise location and plotted into the map .
Metal detectors are increasingly being used to assist the surface penetrating radar (SPR, Surface Penetrating Radar) and other ground-penetrating radar system to work. Originally developed by the United Kingdom (Britain) developed for detecting plastic landmines SPR system is able to locate the surface 30 m below the abnormal objects. The system also provides a series of clues to help users identify not yet dug up the evidence.
But even find the location of the metal artifacts, it is only half the battle. Sometimes, metal artifacts left half of the original look. Mid-1990s, Plymouth on Man Battle (Battle of Monmouth) analysis of the process, the U.S. archaeologists have discovered many guns mottled surface warheads will be kept as thin as chewing gum. In order to determine the size of the original, a Ming Jiaodan. Sivilich (Dan Sivilich), engineer-turned archaeologist invented a formula that combines the physics and chemistry, is used to calculate any non-spherical musket The original bullet diameter. It (well-deserved) is called "Sivilich formula" (Sivilich Formula), now in the archaeological field throughout the world use every day.
