The CaO concentrations of the garnet are decreased from the core to the rim, while its MnO concentrations are increased, suggesting the retrograde origin of such CaO—MnO zoning.

Spatially resolved Sm–Nd dating of garnet single crystals has been conducted previously (e.g. [12], [13], [14], [15]). However, these studies. An alternative approach is to use Lu–Hf and/or Sm–Nd isotopic systems to date garnet, which is a common porphyroblast phase that can.

Garnet geochronology provides important information on the timing and conditions of metamorphism.

Lutetium—hafnium dating is a geochronological dating method utilizing the radioactive decay system of lutetium — to hafnium — The trace concentration of the Lu and Hf in earth materials posed some technological difficulties in using Lu—Hf dating extensively in the s. Lutetium is a rare-earth element , with one naturally-occurring stable isotope Lu and one naturally-occurring radioactive isotope Lu.

We present coupled Lu—Hf and Sm—Nd dates from multiple growth zones within a single large garnet porphyroblast in an eclogite from the Huwan shear zone in the Hong’an orogen, central China. The eclogite sample contains large garnet porphyroblasts up to several centimetres in diameter and a second major population of smaller, millimetre-sized garnet grains.

The sample containing the garnet is a coarse-grained pegmatite from the Campo basement unit northern Italy , part of the Austroalpine realm.

Но этот голос был частью его. Слышались и другие голоса – незнакомые, ненужные. Он хотел их отключить. Для него важен был только один голос, который то возникал, то замолкал. – Дэвид, прости. Он увидел пятна света. Сначала слабые, еле видимые на сплошном сером фоне, они становились все ярче.

Но он настолько устал, что ему было не до любопытства. Сидя в одиночестве и собираясь с мыслями, Беккер посмотрел на кольцо на своем пальце. Зрение его несколько прояснилось, и ему удалось разобрать буквы. Как он и подозревал, надпись была сделана не по-английски. Беккер долго вглядывался в текст и хмурил брови.

Мидж, ну пожалуйста, успокойся. Ты знаешь, что я не могу… Она фыркнула и снова повернулась к клавиатуре. – Я распечатаю список. Войду, возьму его и тотчас выйду. Давай ключ.

На экране Танкадо рухнул на колени, по-прежнему прижимая руку к груди и так ни разу и не подняв глаз. Он был совсем один и умирал естественной смертью. – Странно, – удивленно заметил Смит.  – Обычно травматическая капсула не убивает так. Иногда даже, если жертва внушительной комплекции, она не убивает вовсе.

– У него было больное сердце, – сказал Фонтейн.
