The placer deposits dominated Neendakara-Kayamkulam sector along the Kerala coast on the southwest coast of India may be characterized as a dynamic, unstable beach based on shoreline oscillations observed over the past years. Both long-term and short-term shoreline variations can be easily linked di...

Alaxadrite deposit in the country is located in the southeast of the city of Kandy 60 kilometers, more than 2000 years of mining history, is a large comprehensive placer. The plateau group containing gems is composed of granulite facies metamorphic rocks with a mineralized area of about 2000 ...
Duobuza Copper Deposit was discovered by the Fifth Geological Team of Tibet Bureau of Geology and Mineral Exploration during survey and assessment of placer gold in 1997. With continuous investment in geological survey in the area, a new batch of mineral localities have been found around Duobuz...
In most cases, the economic viability of the deposit depends upon the presence of other valuable minerals. The mines are usually underground operations that follow the veins and cavities where the native silver occurs. Native silver is usually without a characteristic crystal habit. When it forms ...
3. Geology of the ore deposit It took more than half a century after the discovery of the Dachang gold deposit to accomplish detailed exploration. In 1956, placer gold was discovered, and prospecting was carried out. Until the 1970s, the inferred placer gold reserve was 2.88 tons in the up...
The dominant alteration is sericite-quartz-feldspar, with a lower proportion of Fe-carbonate than the KCD deposit (Allibone et al., 2020). In contrast, the KCD deposit mainly displays mineralisation controlled by chemical-stratigraphy (BIF layers), particularly when these are cut by fold and ...
