Archaeologists and geologists in Spain studying Las Mdulas, the largest known open-cast gold mine of the Roman Empire, have discovered it was a much bigger operation than previously thought. The mines, located in the province of Len, form a unique cultural landscape that was designated by UNESCO as a World Heritage Site in 1997. The mining technique used by the Romans known as ruina montium, Latin, wrecking of mountains created a challenging terrain for later archaeological exploration, and the full extent of the mining operation had been underestimated, until now.

Using a Light Detection and Ranging LiDAR laser device attached to an aircraft, the researchers have identified a larger, more complex system used by the Romans to extract gold in the 1st century BC. It was an ancient Roman gold mine operation that, according to one contemporary record, involved a slave labor workforce of 60,000 men.
8220The volume of earth exploited is much greater than previously thought and the works performed are impressive, having achieved actual river captures, which makes this valley extremely important in the context of Roman mining in the north-east of the Iberian Peninsula,8221 says Javier Fernnde Loano, a geologist at the University of Salamanca.
8220We have established that the labor that went into extracting the resource until its exhaustion was so intensive that after removing the gold from surface sediments, operations continued until reaching the rocks with the auriferous quart veins underneath,8221 explains Fernnde Loano.
According to the research team, this study of ancient Roman gold minesin the Eria valley is the first piece of 8216geo-archaeology8217 performed with LiDAR in Spain.
The Roman Project property is located directly south of the existing Trend Mine. Coal seams of economic interest are located in the Gates and Gething Formations as at the Trend Mine. The structure of the Roman Project coal seams consists of a large syncline the axis of which strikes northwestsoutheast.

The Romans extracted gold from mines at Wales, Devon and Cornwall. The price of mining gold took a leap when the Romans developed hydraulic mining in the Spanish mines. Rivers were re-channeled and destroyed. Strabo wrote that this method produced more gold than the deep mines. Some of the Roman mines in Spain were 650 feet deep.
A historic site in Spain, Las M233dulas was once the most important gold mine in the Roman Empire. Named a World Heritage Site by UNESCO, the area, which is near the town of Ponferrada in the.
The main period of working began in 1933 with the formation of Roman Deep Ltd. At least some gold was produced about this time as gold from Roman Deep together with the Dolgellau mines, Prince Edward Mine and Marina Mine provided gold for Princess Marinas wedding ring in 1935 gold from the bar produced was also used for other royal rings.

Las Meacutedulas is a natural environment that is considered one of the most singular in Spain.nbsp.
Therefore, it was declared World Heritage Site by UNESCO in 1997 and Natural Monument in 2002.
Originally Las Meacutedulas were a mining site. Considered the biggest gold mine built by the Roman Empire, it was abandoned in the 3rd century after extracting 800,000 kg gold.
Thereafter, the native vegetation began to gradually cover the hills of red sand. These hills were formed in Roman times by turning over the interior layers of the earth. Thus, they created galleries in which they injected pressuried water with which they crumbled the slopes of the mountains, bringing the mineral to the surface.
The result is an environment with a beautiful landscape in which the ground has been shaped over time in fanciful reddish formations that contrast with the green of the forest that partially cover them.
There are some spots of great beauty such as the lake of Carucedo it is believed it was made up of stagnant water during mining or the viewpoint of Orellaacuten, from which you can get a good view of this peculiar environment of the province of Leoacuten.
As architectural remains from its industrial and ethnographic past, you can visit the remains of the metallurgic village of Orellan. The vegetation mainly consists of forests of holm oaks, oaks, kermes oak and chestnut.

Sep 20, 2014nbsp018332Mining in Spain began as early as 25 BC, and was done primarily in the Las Medulas area. As prospectors fanned out and explored new areas, gold was soon found in the Almeria area in the Northeastern corner of Spain. Mining activity really got started in Spain after the Roman invasion. Wanting to increase their.
