片麻岩

The granite vein which width is about 0.5m filled in banded amphibole-gneiss along the tension crack. The milk-white vein strides over ghyll like a white dragon crossing river.

岩岩脉，走向45°，宽0.5米，沿张节理充填条带状角闪斜长片麻岩中,乳白色岩脉跨过溪流，犹如白龙过江。

The SHRIMP age data and geochemical results of the Palaeoarchaean dioritic gneiss and fine-grained trondhjemite of the ancient Dongshan rock belt from the Anshan area are reported in this paper.
