LM and TEM Investigations on Hungarian Neogene lignites.

Summary: The LM and the TEM structure of the secondary wood of two lignite samples and the spore-pollen data of two Upper Pliocene Formation (Tihany and Torony) are presented in this paper. The ultrastructure of the (Sequoia) wood remains was investigated on non-experimental and partially dissolved samples with diethylamine and merkaptoethanol. The different layers (S3, S2, S1) of the secondary wall were well perceptible on some samples after dissolution with diethylamine. The spore-pollen composition of the Tihany Formation was investigated on two localities (Szombathely and Iharosberény), and the Torony Formation from one locality. The association of vegetation was different on the investigated localities. [Acta Palaeobot. - Supplementum No. 2]
