Rum part of this blending process, light rums may be filtered to remove any colour gained during ageing. For darker rums, caramel may be added to adjust the colour of the final product. Artificial ageing attempts to match the molecular composition of aged rum using heat and light. Besides rum punches, cocktails such as the Cuba libre and daiquiri have well-known stories of their invention in the Caribbean. Tiki culture in the U.S. helped expand rum's horizons with inventions such as the mai tai and zombie. Other well-known cocktails containing rum include the piña colada, a drink made popular in America
Ita Mai Tai sometimes reach thicknesses of over , with geochemical differences between the various sectors of the seamount. These ferromanganese crusts have aroused scientific interest in the seamount. Some evidence of hydrothermal alteration has been found in the form of barite deposits within the ferromanganese crusts. Ita Mai Tai erupted first during the Albian and Aptian periods. Another episode of volcanic activity may constitute late stage volcanism; it might be represented by Campanian volcaniclastic rocks, an Eocene dome and Pliocene cones on Gelendzhik seamount. such late volcanism has been observed in other neighbouring seamounts as well. An uplift episode took place during
