Minerals of the atacamite group from ores at the bottom of the Atlantic Ocean

The study of samples with minerals of the atacamite group from the ore fields of the Atlantic Ocean made it possible to reveal their genetic features and hydrothermal nature. The objects were observed with the help of underwater television directly on the ocean floor. The lifted samples were initially studied under binoculars aboard the R/V Professor Logachev. Due to their characteristic rich bluish-green color, atacamites were easily recognized among other minerals, and their diagnosis was further confirmed by the results of studying optical properties in transparent polished sections, under an electron microscope, and during X-ray diffraction analysis.
