Abstract：
Of the early Eocene amber deposits known across the world, Belgian amber has been mostly absent from the relevant literature. We reinvestigated amber held in the palaeobotanical collection of the Royal Belgian Institute of Natural Sciences, Brussels, which derived from three localities in Belgium that originated from two geographical areas (Leval-Trahegnies and Orp-le-Grand). Using Fourier transform infrared (FTIR) spectroscopy we show the close chemical relationship of Belgian amber to the early Eocene Oise amber from the Paris Basin, and highlight the potential effect of weathering on the amber chemistry. The amber derives from a very similar botanical source as the Oise amber (Combretaceae or Leguminosae-Caesalpinioideae), but from different coeval basins. The two Leval-Trahegnies localities provided amber that exhibit different stages of weathering (heavily fissured and crazed, darkened) and lacking any inclusions. The Orp-le-Grand locality provided the least weathered amber, with one amber piece containing two inclusions: a mite and a new genus and species of hemipteran (Cativolcus uebruum gen. et sp. nov.), and a second one that preserved the impression of insect wings pressed into the surface.
摘要：
在全世界已知的早期始新世琥珀矿床中，相关文献中大多没有比利时琥珀。我们重新调查了比利时皇家自然科学研究所的古植物学收藏中的琥珀，布鲁塞尔,源自比利时的三个地区，分别来自两个地理区域（Leval-Trahegnies和Orp-le-Grand）。使用傅立叶变换红外（FTIR）光谱，我们显示了比利时琥珀与巴黎盆地早期始新世Oise琥珀的化学关系，并强调了风化对琥珀化学的潜在影响。琥珀来自与Oise琥珀（Combretaceae或豆科-Caesalpinioideae）非常相似的植物来源，而是来自不同的中世纪盆地。两个Leval-Trahegnies地区提供的琥珀表现出不同的风化阶段（严重裂隙和疯狂，变暗)，没有任何夹杂物。Orp-le-Grand地区提供了最少的风化琥珀，一个琥珀色的作品包含两个内含物：一个螨和一个新的半翅目属和物种（Cativolcusuebruumgen。等sp.11月。),第二个保留了昆虫翅膀压入表面的印象。
