Thanks for the help!

I looked up all the information about the volcanic rocks from 55 leg DSDP, but unfortunately, there is not any information on the gold content.

Inna Safonova

Про золотоносность OIB упомянуто в автореферате Голубевой Э.Д. из ДВГИ ДВО РАН со сылкой на работы Говорова. Если надо могу выслать автореферат. Также этот вопрос обсудаетс в Webber et al., 2012, Geology (Golden plumes: Substantial gold enrichment of oceanic crust during ridge-plume interaction). У меня нет доступа к Geology.

Инна, огромное спасибо за помощь.

В монграфии и.я. Некрасова "геохимия, минералогия и генезис золоторудных месторождений" есть данные по содержанию золота в базальтах гавайских островов и ссылка на тезисы китайского автора за 1987 год. Вот ищу более свежие работы.

Еще раз благодорю за помощь!

Удачи, павел! Тема - интересная. Будем ждать ваших публикаций.

I recorded Au concentration of up to 11.7 ppm in basaltic intrusion cutting granite in south Western Australia.

Thank you Walid!

I found many information about land gold deposits of Pacific ring

Hawaiian basalts are contain 2.4-2.7 ppb of Au. I can not find concentration of gold in intraplate basalts of the Pacific (seamounts of the Emperor volcanic chain (N-W Pacific)).
