Ten embedded fossil logs sampled in situ from the middle Eocene volcano‐sedimentary rocks close to Suffield Point in the Fildes Peninsula, King George Island, Antarctica, are assigned to Protopodocarpoxylon araucarioides Schultze‐Motel ex Vogellehner, Phyllocladoxylon antarcticum Gothan, Agathoxylon antarcticum (Poole & Cantrill) Pujana et al., A. pseudoparenchymatosum (Gothan) Pujana et al. and an unidentified angiosperm wood. Differences in the taxonomic representation and growth‐ring characters of the Eocene woods on King George Island and coeval assemblages from Seymour Island, on the western and eastern sides of the Antarctic Peninsula respectively, are interpreted to result from environmental and climatic gradients across the Peninsula Orogen during the early Palaeogene. In particular, a precipitation gradient inferred across the Peninsula at that time might have been induced by a rain‐shadow effect.

乔治王岛菲尔德斯半岛下新生代火山沉积岩中的新化石木材及其对南极半岛始新世气候梯度的影响

采样十大嵌入式化石记录原位从菲尔德斯半岛，乔治王岛，南极的中始新世火山沉积岩靠近萨菲尔德点，被分配到Protopodocarpoxylon araucarioides舒尔茨，汽车旅馆前Vogellehner，Phyllocladoxylon antarcticum Gothan，Agathoxylon antarcticum（普尔＆ Cantrill）Pujana等，A。 假parenchymatosum（Gothan）Pujana等。和一个不明的被子植物木材。南极半岛西侧和东侧的乔治国王岛上的始新世森林和西摩岛的后代组合的分类学表征和年轮特征的差异被解释为是由半岛造山带上的环境和气候梯度造成的在古近纪早期。特别是，当时在整个半岛上推断出的降水梯度可能是由雨影效应引起的。
