Перевод: auriferous
[прилагательное] золотоносный; золотосодержащий; златоносный
Тезаурус:
- At Glenhead and Moorbrock Hill, adjacent to the Loch Doon granodiorite (MRP 48; MEG 261), and in the Leadhills area, quartz veins and disseminated arsenopyrite zones are auriferous (MEG 230 and 260).
- The most important have been the Dolgellau area of North Wales, where auriferous quartz veins in Cambrian shales have yielded a total of about 4 tonnes of gold, and the Pumpsaint area of Central Wales where auriferous quartz veins cut pyritic Silurian shales.
- In terms of regional structural controls most of the auriferous deposits in the project area are spatially related to first-order faults and shear zones within the belt and along its margins; to major anticlinal fold axial traces and limb shears; or to the fracture envelopes around the major granitoid intrusions Follow-up geochemical field testing of soils for arsenic over selected targets outside the known gold mining districts was 60-;70% successful in demonstrating that certain predicted structural settings would be mineralised.
- Not all the quartz veins are auriferous and the Tyndrum Main Vein, previously worked for lead and zinc, does not carry significant gold.
- The veins are often auriferous where they cut graphitic shales but not where the host rocks consist of non-graphitic arenites.
- In the Suchna-Rudna area, they sampled auriferous quartz veins hosted by carbonaceous Upper Palaeozoic flysch-type sediments in order to make fluid-inclusion studies for comparison with gold deposits in Spain, Portugal and the United Kingdom.
- Prehistoric communities and pioneers in new territories concentrated on auriferous alluvial deposits which they could work in small groups or even as individuals with only the most rudimentary equipment.
