Wrekin terrane
inferred basement rock terrane of the southern United Kingdom
The Wrekin terrane is one of five inferred fault bounded terranes that make up the basement rocks of the southern United Kingdom. The other notable geological terranes in the region are the Charnwood terrane, Fenland terrane, Cymru terrane and the Monian Composite terrane. The Wrekin terrane is bounded to the west by the Welsh Borderland fault system and to the east by the Malvern lineament. The geological terrane to the west is the Cymru Terrane and to the east is Charnwood Terrane. The majority of rocks in the area are associated with the outcrops that are evident at the faulted boundaries.
Intrusive geology
The older rocks of the terrane rest in the Precambrian with younger Cambrian rocks resting unconformably upon them. The Precambrian rocks are noted to be calc-alkaline plutonic intrusions dated to approximately 700-600 Ma (Phase 1 to Phase 2 Neoproterozoic). These have associated (younger) volcanics that dominate the overlying sedimentary rocks that date between 570 and 560 Ma. The signatures of the rocks are interpreted as having an intra-plate geochemical signature that may be attributed to arc-rifting. The diachronous formations of the bedded Uriconian and Coomb Volcanic Formation.
This brief starts where responsible research should: with the source description of “Wrekin terrane” as inferred basement rock terrane of the southern United Kingdom. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as inferred basement rock terrane of the southern United Kingdom. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q16258617. Authority coordinates are 52.669, -2.552. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
