• Late carboniferous praat met me

  Ice house world south pole covered with huge ice sheet gondwana and laurussia had collided to form pangea

• Nederland in late carboniferous

  land locked between mountain ranges tropical climate at equator

  Sediments from the Variscan mountain range in the south 

  were deposited in a large, fast subsiding, foredeep basin

• Zechstein Play elements

  HC-source rock: Westphalian coals, 

  Kupferschiefer & ZE high TOC 

  carbonates. 

  - Migration routes: permeable rock or 

  faults of/in the Carboniferous and 

  Rotliegend. 

  - Reservoir rock: porous and fractured 

  Zechstein carbonates and sandstones 

  - Seal: Zechstein evaporites. 

  - Structure: fault-dip closures at base

• Precipitation model of the zechstein evaporites?

  anhydrite deposition margin os shallow basin-> subsidence -> more anhydrite -> further subsidence -> creates deep basin where halite can percipitate
