Аннотация
На основе результатов дискриминантного анализа близких по геохимическим характеристикам выборок фанерозойских внутриплитных и постколлизионных гранитоидов А-типа предлагается диаграмма, позволяющая типизировать, по крайней мере, часть образцов А-гранитоидов. Показана применимость предложенной диаграммы для типизации не только фанерозойских, но и докембрийских гранитоидов А-типа.
