Abstract

The marine Quaternary (Chaudian) terrace V in the outskirts of Sudak accommodates layers saturated with lenses and fragments of fossil coal scrutinized by the lithological, coal petrographical, and paleobotanical methods. The results show that this brown coal of the vitrinite composition can be defined as gagate (or jet), a variety of the humic coal formed mainly from the remnants of Araucariaceae or similar coniferous taxa. In terms of the microtexture and composition of plant remnants, this coal is similar to that in the basement bed of terrace V and was likely redeposited from sediments of the Callovian (Middle Jurassic) Kopsel Formation.

摘要

苏达克郊区的海相第四纪（Chaudian）阶地 V 容纳了通过岩性、煤岩学和古植物学方法仔细研究的透镜体和化石煤碎片的饱和层。结果表明，这种具有镜质组成的褐煤可以定义为gagate（或jet），一种主要由南洋杉科或类似针叶类群的残余物形成的腐殖质煤。就植物残余物的微观结构和组成而言，这种煤与阶地 V 的基底层中的煤相似，很可能是从 Callovian（中侏罗世）Kopsel 组的沉积物中重新沉积的。
