Abstract

Abstract: For the first time the plants that gave rise to the Early Cretaceous coals of Transbaikalia (Khilok, Chita‐Ingoda, Bukachacha, and Turga‐Kharanor basins), Amur River region (Bureya Basin), and Primorye region (Razdolnaya River and Partizansk River basins) have been obtained. The plants that produced coals mainly belong to the ginkgoaleans ( Pseudotorellia, Sphenobaiera, and Baierella ), bennettites, and conifers having pinaceous, taxodiaceous, araucariaceous affinity, as well as extinct cheirolepidiaceous and miroviaceous plants. A parallel palynological study has identified a number of the same elements in addition to the cyatheaceous, gleicheniaceous, osmundaceous, and schizaeaceous ferns.

Abstract : バイカル周辺地域 (ヒロク, チタ − インゴダ, ブカチャチャ, タルガ − ハラノールの各堆積盆), アムール川地域 (ブレア堆積盆), 沿海州地域 (ラズドルナヤ川とパルチザンスク川の堆積盆)から前期白亜紀の石炭層を形成した植物化石が初めて得られた. 石炭を生成した植物は主に, イチョウ類( Pseudotorellia, Sphenobaiera, Baierella ), ベネチテス類, そして絶滅したケイロレピス科, ミロビア科植物に加え, マツ科, スギ科, ナンヨウスギ科などを類縁とする球果植物に属している併用した花粉学的研究では, ヘゴ科, ウラジロ科, ゼンマイ科, フサシダ科のシダ植物に加えて, 多くの同様の要素が同定された.
