Much of the geological and gold prospecting I undertake is within the Central Gold Field.

 

Evidence for gold mineralisation in the Dalradian, the main host rock in the Central Gold Field,  comes from the work being undertaken  around Tyndrum where Scotgold are currently planning a mine development at Cononish.

 

The vein at Cononish comprises a  central ore bearing quartz vein which is surrounded by pink orthoclase feldspar. These are common in the Tyndrum region although further veins have thus far not been discovered to the same extent as the Cononish vein.

 

Evidence of such mineral veins exist within the Dalradian Supergroup in the Angus and Kincardineshire region although on a much smaller scale. Without divulging too much about specific localities metasomatised Dalradian quartz veins have been found in association with small amounts of gold.  Examples of such veins are depicted on the top right photograph.

 

Lamprophyres common in the Tyndrum area are also present in the Angus and Kincardineshire region and  although the exact relationship to gold mineralisation is un clear, lamprophyres appear to be commonly associated with gold deposits. 

 

An Angus Glen lamprophyre is shown in the lower photograph and is similar in mineralogical appearance to those found in the Tyndrum area.
