The epidermic structure of Solenites murrayana in Yaojie Formation is similar to that of Solenites murrayana in Yorkshire Jurassic of UK by cuticular analyses.

作者在兰州-民和盆进行环境古植物学的研究中,于中侏罗统窑街组发现了中生代银杏类植物化石的重要代表穆雷似管状叶Solenitesmurrayana L.et H。,通过分析S.murrayana的表皮构造,得出与英国约克郡侏罗纪的S.murrayana具有明显相似性的特点。

Petrologic and geochemical investigations of mafic dikes in detail were concentrated in north Gangdong from southeast China so far, a few half-backed study on mafic dikes of south Hainan and coastal belt of Fujian and southeast Hunan and ore region of some hydrothermal deposits, so systemically and large area investigations of mafic dikes from southeast China is still few and need to undertake in the future.
