Placer of agates at Vertikalny Cape, Eastern Kamchatka
In the area of the city of Petropavlovsk-Kamchatsky, field work was carried out, which included routes through hard-to-reach bays along the coastal cliffs of Avachinsky Gulf. Agates and chalcedony were collected in a boulder and pebble placer southwest of Cape Vertikalny. Their source is volcanic st...

In the area of the city of Petropavlovsk-Kamchatsky, field work was carried out, which included routes through hard-to-reach bays along the coastal cliffs of Avachinsky Gulf.

Ornamental stones are observed among the pebbles and boulders of volcanics. Gray monochromatic chalcedony and low-contrast agates prevail among them, but there are also agates with a contrasting and complex pattern, as well as «moss» and «landscape» agates. The length of the coastal placer, separated by rocky cliffs, is about 2 km. Some agates have inclusions of native copper, from a fraction of mm and rarely up to 5 mm in size, which is of interest for mineral collectors. |
