Procedure for approval of new lithostratigraphic units or amendments

A proposal can be submitted in electronic format to the secretary of the NCS and the subcommissions (text .doc and figures .jpg 96 dpi). The proposal will follow the structure adopted in the Geologica Belgica 2001 volume 4 (1-2) (Guide to a revised lithostratigraphic scale of Belgium).

The subcommissions discuss the new proposal and in case an agreement is reached, its secretary submits this proposal to the NCS secretary for review and insertion in the webpage as “proposals and discussions”. Decisions in the subcommissions are taken preferably by consensus within 3 months after the submission.

During a period of 3 months after insertion in the webpage, comments, disagreements or amendments regarding new units have to be addressed to the secretary of the corresponding subcommission.

After that period, the subcommission re-examines the proposal and requests eventual modifications. Delay should not exceed 3 months.

When a final agreement is reached in the subcommission, the new or modified unit is submitted to the NCS secretary who shall adapt the status of the proposition.

The NCS will then accept or reject the proposition at its next annual meeting, if the proposition can be placed at the website at least two months before the meeting. If accepted the unit receives an official statute and will be added to the revised text.
