ABSTRACT: The Environments of Deposition of the Triassic, Main Buntsandstein Formation, in the P and Q Blocks, Offshore, Netherlands

The Main Buntsandstein Formation in the study area consists of intercalated sandstones, claystones, and siltstones, which are subdivided into five members: the Volpriehausen Sandstone, the Volpriehausen Clay/ siltstone, the Detfurth Sandstone, the Detfurth Claystone, and the Hardegsen Sandstone. These were deposited by coexisting, continental depositional systems, including extensive sand seas, muddy wadis, and braided stream/fluvial systems. Core data and log analyses were used to quantify and map the relative abundance and distribution of these environments of deposition within each of the five members. The maps show the subtle migration of these systems across the study area, possibly in response to climate changes.
