摘要

Valdres群（？成冰纪）已在几个关键地点（Grønsennknippa、Mellane、Ormtjernkampen）进行了沉积学和地层学研究和取样。在选定的地层中寻找化石一直是目标，发现了一个已确定的棘皮形肢端化石，以及其他更不确定遗产的有机物。除了瓦尔德雷斯群演替中存在的杂岩/钛铁矿外，这有助于与东部著名的赫德马克群进行对比。

Sedimentological and palynological investigations of the Neoproterozoic Valdres Group

The Valdres Group (?Cryogenian) has been sedimentologically and stratigraphically studied and sampled in a few key sites (Grønsennknippa, Mellane, Ormtjernkampen). The search for fossils in selected formations has been the target and one identified acantomorphic acritarch was discovered along with other organic matter of more uncertain heritage. In addition to the diamictite/tillite present in the Valdres Group succession, this facilitates a correlation with the well-known Hedmark Group to the east.

期刊介绍： The Norwegian Journal of Geology publishes high-quality, fully peer-review papers from all geoscientific disciplines. Papers are commonly based on regional studies and should emphasise the development of understanding of fundamental geological processes. More specialised papers can also be submitted, but should be written in a way that is easily understood by nonspecialists, and illustrate the progress being made within that specific topic in geosciences. We also encourage initiatives for thematic issues within the scope of the Journal.
