Coat of arms of Cyprus Coat of arms of Cyprus The coat of arms of the Republic of Cyprus depicts a dove carrying an olive branch (a well-known symbol of peace) over “1960”, the year of Cypriot independence from British rule. The background is a copper-yellow colour; this symbolises the large deposits of copper ore on Cyprus (chiefly in the form of chalcopyrite, which is yellow in colour). The arms is not violating the rule of tincture, since the dove is not argent (silver) but blazoned as of the colour proper, i.e. it has the colour it would have in nature, in this case white.
Carbonate-hosted lead-zinc ore deposits brines (10-30 wt.% NaCl equivalent) with pH's of 4.5-5 (buffered by host carbonates). This hydrothermal fluid may or may not carry the required sulfur to form sulfide minerals. Mobile hydrocarbons may have played a role in delivering reduced sulfur to certain MVT systems, while methane and other organic matter can potentially reduce sulfate carried by an acidic fluid. The ore fluid is suspected to be derived from clastic red bed sequences (potential metal source) that contain evaporites (potential sulfur source). Two potential transportation mechanisms for the metal-bearing ore fluid have been proposed. The first involves compaction of sediments in basins
