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.
